"check tel line" message?

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.

I assumed when you say all phones are operating means there's power and are charging.
1. There could be some phones that are loading the Tel line. Disconnect all phones and plug it one by one while checking the dial tone. If all phones gives busy tone, there coulb be a problem in the Trunk line or the Tel Company line.
2. There could be a short or resistance in the line. Check the connection in junction box between your house and the Tel Company cable.
3. If you have an analog Tel set, you can check the dial tone directly from Tel Company cable that comes in to your house.

I hope this helps.
Best Regards.

Plug another phone into the wall outlet and see if you get dial tone. If no dial tone, you will need to have the line repaired. If you do get dial tone, then there is a problem with your fax machine.

The phone is not detecting dial tone on the line. Are you able to hear a dial tone? If not - disconnect the cable at the phone and plug into a different phone. If it works, then the problem is with the Panasonic phone - if it doesn't work - the problem is with the cable, jack, wiring, etc.

ck the red and green wire that goes to the system those 2 make the phones work just do the main main phone first , , it does not sound like the phones are broke you are not getting a dial tone due to no connection to the line itself

Hello,

What you need to do first of all , put of the phone then disconnect it from the power supply allow he phone for about five minute ,then put it on again check the phone respond on your command if the problem remain same or solve.

Note if the problem remain then you will need to send me the name and the mode /serial number of the phone to guide you further.

Thanks.

Hello. If everything else is working, printing and copying, unplug the printer from the power source. Check the telephone line from your phone company by unplugging the fax machine from the wall jack where it is connected to. Plug a telephone device straight to that wall jack and check for a dial tone. If there's no dial tone, contact your phone company. If there is, plug the fax machine back to that wall jack. You can also try replacing the telephone cable with a another known working cable. Plug the printer back to the power source. Check again. Hope this helps.

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.

Verizon sent a technician in

Try the simple things first. Try a different phone. In my case, I had the phone company check - outside was fine. After two hours my phone worked. I figured out what happened in my case. Both phones were dead (battery). I think one died with the phone off the hook. once the phones were fully charged, the phone worked.
