Phone not working

The PNLC1017 is the charger for the handset of some Panasonic cordless phones. One of the compatible handsets is the KX-TGA660 which works with the KX-TG4112 system.

However, the 'Check tel line' message indicates a problem at the base or the POTS (Plain Old Telephone Service) telephone line. The system is not hearing the dial tone. Check that the power adapter is plugged in to a live outlet and is warm. If it's cold, than the power transformer is not working and the base has no power. If there is power, check if the handset message disappears when the handset is close to the base. This is usually rare but indicates a transmitter/receiver in the handset or base is not communicating properly. You can try to de-register all handsets and then register them again.

To check the phone line, I prefer to use an older corded phone. These don't require power to work. First, try a new phone data cord (RJ-11) between the base and the wall jack. (I've seen someone accidentally use a handset cord which doesn't work.) Test if there is a dial tone when this cord is plugged into the test phone. If there is a dial tone, then if the cordless phone base didn't work with the replacement cord, the base is faulty. Replace it or contact Panasonic if the system is under warranty. If you have a DSL fliter, this may be damaged. If it's inside, replace it. If it is in the service box, ask your telephone provider to check it.

If there is no dial tone, you need to locate the other phone jacks for that phone line. Find where your phone service comes in as well. Check if there is a dial tone on another jack for that phone line. If there is no dial tone, check the service box for an RJ-11 jack, Test for a dial tone there if you can plug in the RJ-11 cable. If you have a dial tone at another jack, then the problem is local to the first jack's wiring. You can open the jack and check for loose wires. There are two styles of jacks - screws or punch-down. For the screw terminal, strip the insulation and wrap it under the appropriate screw. For the punch-down keystone jack, you need a punch-down tool. The tool is available from most home improvement/building supply stores, in the wiring section. Do not strip the wire. Use the tool to press the wire down into the correct slot on the jack. See https://www.lanshack.com/wire_phone_jack.aspx for the wiring diagram.

If you can't test the phone line or there is no dial tone at the service box, then you need to contact your telephone provider. It used to be that the provider would always test and fix outside problems for free. Some telephone companies are trying to stop repairing copper wiring. If you have a dial tone at the service box, then the problem is somewhere in the inside wiring. You may want to get someone to find a broken wire in the wall for you. Your telephone company service technicians will do this for a fee.

I hope this helps. I've had the check tel line issue times several times at my home. Twice, the outside line was damaged by mice and repaired by my telephone company. Once, a lightning strike damaged the DSL filter; it was promptly replaced. Other times, the line was damaged by contractors digging too close to the underground utilities. The contractors got the wiring repaired. When our service was switched to a fiber-optic system, we lost one telephone jack when the installer simply didn't plug in the wire. We found the loose wire behind the siding and plugged it into the port in the service box ourselves. Since then, we lost telephone and other service intermittently when the modem card in the service box was failing. That was also replaced by the telephone company technician.

The base needs to be plugged into the wall for power and have a working phone line.

If this telephone is part of a multiphone set there is one base that is connected to a phone line (or if Magic Jack the internet cord). The other phone charging seats work by radio signal from the base unit. Place the phone on the base unit and let it reconnect for a few minutes. If you bought this expansion set without already owning a base unit, you will need to get the base unit or take this expansion set back for a unit that will opperate by itself.

You need to make sure that you have an ADSL line filter connected before any home telephone or DECT base station (eg. a filter is required on the line between your physical telephone device and phone socket). This can also be achieved via a central ADSL phone line splitter.

---------- ADSL Filter -----> Telephone Handset 1 or DECT base station
<--- main telephone line --/
\-----------------------------------> ADSL Modem/Router ---> Computer
\----------ADSL Filter -----> Telephone Handset 2

Hope it helps: let me know how you go.

1. Place the handset in the base.
2. Unplug the AC power adapter from the telephone base.
3. Disconnect all the telephone lines from the telephone base.
4. Allow the telephone base to remain without power for 1 minute.
5. Connect all the telephone lines to the telephone base.
6. Plug the AC power adapter back into the telephone base.

MAKE SURE YOUR POWER CORD IS PLUGGED INTO A GOOD OUTLIT FIRST. CHECK YOUR HANDSET BATTERIES AND MAKE SURE THEY ARE GOOD. MAKE SURE YOUR TELEPHONE LINE CORD IS ALSO PLUGGED INTO A GOOD TELEPHONE JACK. IF THE BASE UNIT IS BAD NEITHER HANDSETS WILL WORK. WHEN ALL ELSE FAILS READ THE ENCLOSED DIRECTIONS AGAIN TO SEE IF YOU POSSIABLY MISSED SOMETHING.

You can remove your telephone line from the base unit and fix it to stranded telephone unit and hear the dial tone.If it heard then some inductor or else part may be broken inside the base unit due high current surge.If the dial tone didn't heard from the other phone also check for the corroded line cord or modular box fault with the tel line.There should be 30 Volt-50Volt D.C.Voltage at your wire ends.

The handset has lost the link with the base. This link codes the handset to the base with a unique security code so others with the same phone cannot use your phone line.

If you changed the battery, try disconnecting the base telephone line and ac adapter for a while (1/2 hour or so if possible).

Remove the battery from the handset as well.

After 1/2 hour, install the battery in the handset, connect the telephone line and ac adapter to the base. Place the handset in the charging base and the link should be established. If not, the phone is defective.

Double check that the telephone cord is firmly plugged into the back of the cordless phone base, the wall outlet, the outlet where the telephone modem is and at the L1/L2 jack on the back of the telephone modem. Your phone is not getting the dial tone line voltage from the telephone modem to the cordless base. There might be a short in the wiring. (It is unclear as to whether you are setting an old phone into this new base or swapping out and using another base with the old phone. Irregardless, the problem would seem to be not in the phone but ratther narrowed to the cord between phone modem and phone base. That is a very good reason to check how firmly the cord is plugged in.

Tip 1 of 2 Recradle the handset for 15 seconds, then lift the handset and press PHONE. Tip 2 of 2 If the handset is not responding normally, you may need to reset your telephone system.
