If you are using Smart Dialing, the dialing rules may have changed or you used the wrong dialing plan code. See the section in the User's Guide or Advanced Set Up guide regarding Smart Dialing.
It is also possible that Tel-Lynx is dialing too fast for your phone service. You can set the dialing speed as follows (higher speed numbers slow the dialing down):
At the dial tone, press FLASH, then 7, then enter your secret code (1234 by default), then press 1, then 9, then 6 to change the dialing speed. Valid speeds are 1 to 9:
|Speed||Tone On Time||Tone Off Time|
Tel-Lynx maintains all of its settings and phone book through power interruptions. When the power is restored, the date will be set to the date when the power was interrupted and the time will be set to 12AM. To warn you of this condition the blue 'M' light on Tel-Lynx will flash repeatedly, and when you go to make a call Tel-Lynx will say "The power was interrupted".
You can ignore this message and make calls like normal.
The first incoming call on the landline will restore the date and time and Tel-Lynx will resume normal operation. You can also press FLASH at the dial tone when you hear this message and Tel-Lynx will guide you to set the clock.
Tel-Lynx keeps a history of the last 50 or so incoming calls regardless of whether they are blocked or not.
To see the history of the caller ID using your telephone, at the dial tone press # # 5. The latest call will be displayed on your telephone's caller ID screen first. Tel-Lynx wil say the date and time of the call and tell you if the call was blocked.
To see the history of the caller ID using the PC software, use the #history command. This will create a file in the SupportFiles folder called "history.txt" with the caller ID history. The first digit of every line is the outside line the call came in on. The outside line number is followed by up to three characters: "?" means that the caller ID had a checksum error, "W" means the call was a waiting call, and "*" means the call was blocked.
Yes. All you have to do is add the phone number of the gate's call box to Tel-Lynx's phone book. If you are using Distinctive Ringing, make sure the contact for the gate has its preferred user set to "Anyone Only".
If you're receiving unwanted calls after you've set up Tel-Lynx, you may have accidentally set Tel-Lynx into Ring-through mode. To put Tel-Lynx back into Personal Assistant mode so that calls will be screened, pick up the handset, and at the dial tone, press Flash, then 7, then your secret code (default 1234), then 1 (set up answer and call out modes), then enter your Personal Assistant mode (press 1 for mode I, 2 for mode II, or 3 for mode III). Note: Firmware prior to 1.3.X had a different key pad assignment (1 for Ring-through, 2 for Personal Assistant mode I, etc).
You can also cancel a temporary Ring-through mode as follows: At the dial tone, press #6#.
Another possibility is that you have added a wildcard whitelisted contact that has too broad a range. For instance, adding 011* so that all international calls at allowed through may allow a lot of improperly formatted calls through. Unfortunately many times the prefix '+' is left off international phone numbers in the caller ID making the caller ID improperly formatted. In order for Tel-Lynx to allow these legitimate, but improperly formatted calls through or to be qualified it must add the '+' back in for these improperly formatted calls or they would be rejected as spam calls. So be careful when adding wildcard whitelist contacts to not make the range to broad.
If you have traditional phone service from your local telephone company and have multiple telephones connected to wall jacks throughout your house, we have a Wall Jack Kit available for exactly that purpose. The Wall Jack Kit allows you to use your telephones, with TLC or the Guardian, on the second (unused) line in your wall jacks.
You must have only one phone service connected to your house to use the Wall Jack Kit. For each telephone, you'll plug an adapter into the wall jack, and using your telephone's phone cord, connect your telephone to the L2 jack on the adapter.
To hook up the Guardian, plug an adapter into a wall jack, and using the provided phone cord, connect Guardian's LANDLINE jack to the adapter's L1 jack. Then connect one of the Guardian's PHONE jacks to the L2 jack on the adapter. Then connect a telephone's phone cord to the other PHONE jack on the Guardian.
To hook up TLC, plug an adapter into a wall jack, and using the provided phone cord, connect TLC's LANDLINE jack to the adapter's L1 jack. Then connect TLC's '2' jack to the L2 jack on the adapter. Then connect a telephone's phone cord to the '1+2' jack on TLC.
Please watch our video on the Tel-Lynx website that shows you how use the second line in your wall jacks.
Yes. Tel-Lynx is compatible with your existing telephones: single-line telephones for Guardian, and single or two-line telephones for Guardian Plus, TLC and TLC Plus. It's even compatible with old-time rotary dial telephones!
Tel-Lynx is not a phone service. It uses your existing phone services, and you can change services at any time. And there is no additional monthly fee for using Tel-Lynx.
If the power is out, you must call 911 by picking up your mobile phone and dialing directly, or by using a wired telephone connected directly to your landline service. Tel-Lynx will not work if the power is out unless is it plugged into a working UPS. Please see the Tel-Lynx User's Guide for more information.
Tel-Lynx can detect three different incoming ring patterns on the landline, and can then automatically select the user who will receive the call.
Yes, Tel-Lynx works with fax machines in two ways. The fax machine and Tel-Lynx can share the landline, or you can attach your fax machine to one of Tel-Lynx's inside lines.
Fax Sharing the Landline with Tel-Lynx:
In this method, both Tel-Lynx and the fax machine are attached to your landline. There are two ways this can work. The easiest way is if your fax machine is designed to work with a telephone answering machine/device (TAM / TAD). HP, Panasonic, Brother, and others have fax machines that have this capability. Check your fax machines user's guide to be sure. If you have a fax machine that works with answering machines make sure you have set it up to work with an answering machine (TAM / TAD) as described in the fax machine's user's guide. Tel-Lynx can be set up to answer calls on the first ring, but will release the telephone line to the fax machine seven seconds after it hears the fax tone (CNG). This allows the fax machine to hear the fax tone (CNG) and take over the call.
If your fax machine is not able to work with an answering machine, you will need a separate fax phone number using a service like RingMaster® to be able to share the phone line with Tel-Lynx. Calls made to the fax number will have a different ring pattern than calls made to your primary phone number. Set up Tel-Lynx to ignore the ring pattern for calls to the fax number, and set up your fax machine to answer calls with that ring pattern (or to not answer a call for several rings).
Fax Attached to One of Tel-Lynx's Inside Lines:
In this method, the fax machine is connected to one of Tel-Lynx's inside lines (just like your telephones are). Set up a user on Tel-Lynx with the name "fax" (case insensitive) and set up the fax user as follows:
• Set Ring Pattern to two rings,
• Set Ring Mode to ring only the inside line attached to the fax machine, and
• Set Select Outside Lines to be the landline only.
Set up your fax machine to only answer a two-ring pattern. When a call from another fax machine comes in and Tel-Lynx hears the fax tone (CNG), it will skip the qualification process and immediately ring the inside line for the fax machine with the two-ring pattern. When the fax machine answers, it will be immediately connected to the calling fax machine. In this method, you do not need a service like Ring Master or a separate phone number for your fax machine.
When sending a fax, Tel-Lynx will bypass the Auto Create Contact option (if enabled) as soon as it hears the fax tone.
Tel-Lynx supports seven users plus a general user called "anyone". Each user is assigned a mailbox and can be assigned one of nine ring patterns.
There are several ways. If your telephones have a Visual Message Waiting Indicator, it will show when new messages are waiting. In addition, when you pick up the telephone to make a call, you'll hear a stuttered dial tone. On the Tel-Lynx box, the message light ('M') in the 'Status' section will also be flashing.
You can press # 8 at the dial tone to listen to your voice mail message(s).
It's natural to pick up a telephone and dial when you're at home, and our Dial-By-Name is fast and easy. You just dial a few letters of someone's first and last names followed by the star key, and then press the key for their phone type (Home, Mobile, Work, etc.) or press * to call any phone type. Tel-Lynx then looks up their phone number in its phone book and dials it for you. It's that easy! If the name and phone type are not unique, Tel-Lynx will ask you to select the one you want to call.
Voice dialing is great when you have your hands full, like when you're driving a car, but when you're at home, it's much faster to dial by name on a telephone. TLC does support voice commands on your mobile phones, including voice dialing, but you have to dial something to initiate voice dialing, so why not just Dial-By-Name?
With TLC and TLC Plus, Tel-Lynx's phone book can be imported from your mobile phone(s) and its Dial-By-Name feature requires no internet connection and no monthly fee.
You can operate Tel-Lynx in either Smart Dialing mode or Direct Dialing mode.
To simplifiy setup and use, Tel-Lynx operates in Direct Dialing mode after initial setup. You can then enable Smart Dialing if you want to use Tel-Lynx's advanced dialing features.
With Direct Dialing mode, Tel-Lynx connects your telephones directly to your landline service as soon as you take your telephone off-hook to make a call. The advanced dialing features are not available in this mode and you will dial out as you always have.
Smart Dialing mode allows you to use the advanced dialing features like Dial-By-Name, Speed Dialing, Redial / Call Back, and 4-Digit Dialing. When in Smart Dialing mode, the dial tone you hear when you pick up your home telephone is coming from Tel-Lynx, not from your Telco, VoIP, or mobile phone provider. Tel-Lynx sits between your telephones (and PCs, laptops, and tablets) and your phone service providers. So Tel-Lynx can do lots of extra things for you that those services cannot do alone. When you make a call, Tel-Lynx automatically selects an available phone service to place your call. You can also specify which phone service you want to use before you place a call.
Inside lines are connected to telephones, PCs, laptops, and tablets. Inside lines 1 and 2 connect to telephones, and inside lines 3 and 4 connect to the phone apps running on your PCs, laptops, and tablets.
Outside lines connect to phone services. Outside line 1 connects to your landline, line 2 connects to a second landline (or Skype), and outside lines 3 (and 4) connect to mobile phone 1 (and 2).
You can connect Tel-Lynx's landline port(s) into anything you can plug a regular telephone into. These include:
- traditional wire line service from your local telephone company or PBX
- phone service provided by your cable company
- wireless home phone service offered by Straight Talk®, AT&T, Verizon, and others
- VoIP systems like Vonage®, Ooma®, and magicJack.
A landline is optional with TLC. You can use TLC with your mobile phones only if you want. If you have more services, all the better--you'll just have more options as to how to make a call.
The Guardian is designed to be used with a landline only.
You get the TLC app on Google Play by searching for "Tel-Lynx" or go to
You can install it from there.
It depends. If you are using a Bluetooth® Audio Receiver (such as the Logitech Bluetooth Audio Adapter) with your home stereo, then yes. TLC uses the Handsfree/Headset Bluetooth Profile, so there should be no conflict with this type of device.
If you are using a Bluetooth device that can answer a mobile phone call (uses the Handsfree or Headset Bluetooth Profile), then no. TLC cannot be connected at the same time as another device that uses the Handsfree or Headset Bluetooth Profile.
You can always make or answer a call directly on your mobile phone without manually disconnecting your mobile phone from TLC. TLC will automatically disconnect and reconnect the audio appropriately.
While on a call, you can command TLC to transfer the audio to or from your mobile phone. Unlike other systems, TLC will never leave you and your caller in silence; it will never inappropriately steal the audio from your mobile phone when you get within range.
When you first use TLC or TLC Plus, you'll need to complete a one-time pairing of your mobile phones. The pairing procedure differs on each type of mobile phone: Android, iPhone, Blackberry, Windows, or flip phone. Follow the procedure below, or go to the Videos page and find the video for your type of phone.
1. Set TLC into pairing mode. At the dial tone, enter the setup menu by flashing the switch hook, then press 7, then enter your secret code (1234 by default). Once in the setup menu, press 437 to pair your first mobile phone to outside line 3. Once you have paired one of your mobile phones on line 3 you can repeat this procedure to pair your second mobile phone on line 4 by pressing 447 after entering the setup menu. In either case, TLC will be discoverable by your mobile phone for two minutes.
2. Using the Bluetooth® menu on your mobile phone, search for TLC, and select it to continue pairing. Your phone's menu may be labeled "Search", "Scan for Devices", or "Add a Device". You may have to go to a menu called "Paired Devices" first. If in doubt, consult your mobile phone's owner's manual.
3. If your mobile phone asks for a security code, use 4321.
4. If your mobile phone asks whether to give TLC permission to access your mobile phone's phone book, answer Yes, and be sure to check the "Don't ask this question again" box (if there is one). This allows you to download your mobile phone contacts into TLC's phone book.
5. If your mobile phone asks whether to give TLC permission to access your mobile phone's text messages, answer Yes, and be sure to check the "Don't ask this question again" box (if there is one). This allows you to send and receive text messages through your mobile phone using TLC.
6. Some mobile phones have an option that requires that you give permission every time TLC connects. Set this option so you don't have to give permission every time your mobile phone comes within range of TLC.
NOTE: If you want to unpair TLC from your mobile phone, use TLC's "Set-Up Outside Line" menu to unpair the mobile phone from TLC. Then use the Bluetooth menu on your mobile phone to unpair (forget or delete) TLC from your mobile phone's paired list.
For the best audio quality, your mobile phones should be in the same room as TLC. Bluetooth® specifies 30 feet, but that's under ideal circumstances (no walls and no other interference). If not in the same room, make sure there's only one wall, floor, or ceiling between TLC and your mobile phone. If you're using two mobile phones with TLC, keep them separated by a foot or more so they won't interfere with each other.
TLC will automatically reconnect to your paired mobile phone when you arrive home. On some mobile phones, you may need to set the Bluetooth® connection to "automatically connect" rather than have it ask your permission every time. See your mobile phone's manual for more information on how to set up Bluetooth on your mobile phone.
TLC can be used to conference all your connected phone services, and can also be used with call waiting and three-way calling on phone services that support these features.
Many mobile phone services have conferencing capability. TLC supports all these conferencing methods.
You must have Phone Book Access Profile (PBAP) on your Bluetooth®-enabled phone in order to download your mobile phone's phone book to TLC or TLC Plus. After you have paired your mobile phone with TLC, you can use the "Outside Line Set Up" menu to inquire as to whether your mobile phone has PBAP.
You can also use a smart phone app that will allow you not only to download, but to also synchronize TLC's phone book with your mobile phone's phone book.
Many businesses and communities use a PBX (Private Branch Exchange) to provide phone service to offices or residences. PBXes generally allow you to directly call another extension on the system by dialing three or four digits. To dial a regular phone number, you generally need to dial 9 first.
Tel-Lynx is compatible with PBXes that can be used with standard telephones and that require at least three digits to dial an extension. In other words, if you can use your own telephones to make calls, you can use Tel-Lynx.
When in PBX mode, Tel-Lynx will automatically dial '9' at the appropriate time. Tel-Lynx users should not dial 9 when making an outside call.
For use with Tel-Lynx's Dial-By-Name, a contact's phone number can be marked as having a local extension on the PBX.
To directly dial an extension on the PBX, simply dial the extension number. After a preset period of time, Tel-Lynx will place the call to the extension. To dial without waiting, dial the extension and then press #.
You can keep over 3000 contacts in the Tel-Lynx phone book.
Use TLC's Manage the Phone Book menu to download your mobile phone's phone book. TLC will automatically merge any new contacts into its phone book. This works for any mobile phone that has Bluetooth® capability and supports the Phone Book Access Profile (PBAP). Our Android app is even more powerful and provides the best way to synchronize your phone books.
Yes, you can use rotary dial telephones with Tel-Lynx even if your phone service does not support pulse dialing. Tel-Lynx takes care of translating dialed digits to DTMF signals (touch tones) when necessary.
It's fun and easy to use Tel-Lynx with a rotary dial phone. You can even Dial-By-Name! And when you're on a call, you can navigate phone trees by simply dialing the required digit. Go to the Support page on this website to download the PDF of the User Manual. There you will find more information on how to dial the star '*' and pound '#' keys using a rotary dial telephone.
Tel-Lynx is designed to drive your house telephone wiring (wall jacks) with multiple connected telephones (up to 5 REN; Ringer Equivalence Number). If you have no traditional phone service connected to your house, you can use Tel-Lynx to drive the wall jacks. It is best to make sure you are completely disconnected from your local telephone company's outside wiring before doing so. Most houses have a telephone service box in their basement, attic, garage, or on the outside of the house called the "telephone demark box". Inside this box you will find a phone cord plugged into a phone jack, or possibly two phone cords plugs into two jacks. Simply unplug these phone cords from the jacks and your house wiring is now disconnected from the local telephone company outside wiring.
If you have digital cable company phone service, Vonage®, Ooma®, or a wireless home phone service from companies such as AT&T, Straight Talk®, or Verizon, where a phone service unit is already plugged into one of your wall jacks, you simply plug your phone service unit into Tel-Lynx, and then plug Tel-Lynx into the wall jack.
If you have a single line, traditional phone service from your local telephone company (AT&T, Verizon, Qwest, etc.) connected to your house, you can use our Wall Jack Kit to connect your telephones and Tel-Lynx to the second (unused) line in your wall jacks. It is a good idea to make sure the second line in your walls jacks is not connected to your local telephone company's outside wiring. See above for locating your telephone company's phone service (demark) box. Make sure you only disconnect your secondary phone service from the local telephone company outside wiring. If there is only one phone cord and one jack inside the demark box, your second line is not connected to the local phone company and you should leave it alone.
If you have two (2) traditional phone services from your local telephone company connected to your house, this can be very challenging to set up and may require professional help to install Tel-Lynx for use with your wall jacks. In this case, it's much simpler to unplug all your telephones from your house telephone wiring (wall jacks) and set up Tel-Lynx with a modern day cordless phone system, where there's only one point of connection from your cordless phone base station to Tel-Lynx, and one connection from Tel-Lynx to your local phone service. Modern day cordless phone systems support six to twelve remote phones, are relatively inexpensive, and are readily available online and in local stores that sell electronics.
Tel-Lynx is designed for use in countries that use the North American Number Plan. Tel-Lynx is certified by the FCC for use in the United States and its territories. Using Tel-Lynx in a country other than the US and its territories may violate that country's laws.
Yes. It's a good idea to routinely connect Tel-Lynx to your PC so that it can back up your contacts and set-up information. Remember to keep the PC backed up as well. You will need a Windows PC running Vista, Win 7, 8.x, or 10 to run the PC software.
Yes. When you install a new copy of the PC software, any new firmware will automatically be installed on Tel-Lynx. You will need a Windows PC running Vista, Win 7, 8.x, or 10 to run the PC software.
To see what firmware is installed on your unit, at the dial tone, press '# # #', then press and hold '6' for one second. Do not hold the '6' for more than two seconds. The firmware revision will appear on your caller ID screen.
