With the lines lit on the phone, it's indicating an off-hook condition or no battery from the line. Check the lines for dial tone at the demarc to determine if it's phone company problem. Thank you. Jer

The phone display says check phone line?

If you have dial tone then the part of the phone that senses the line is malfunctioning. If you do not have dial tone, (more likely. then check your phone cord, phone jack (try using a different jack or cord or you can test the ones you are using with a different telephone). Most likely there is some sort of short circuit or break in the phone line preventing the phone service from reaching the phone base.

My phones are not working at says out of range.

When a cordless phone says "Out of Range" or "Searching for Signal", there are a number of possible issues (assuming you are close to the base). 1) The handset battery may be low and not taking a charge. If the battery is more than a year old (including time spent in storage), replace the batteries for both handsets.
2) The base may not have power or an incoming telephone line signal. Check that the power adapter is warm (power to the base). Use another phone cord (and a second phone (preferably corded) to check for a dial tone). If a second phone has no dial tone, see below for diagnosing a phone line.
3) The phone base has lost the registration information for the handsets. A way to reset the phone is to unplug the power cord (from both the wall outlet and the phone base) and the phone data line and unplug the batteries from all handsets. Wait several minutes then plug in the base power and data cords and then reconnect the phone batteries. You may want to re-register the handsets. This is done by putting the handset in the main charging base for 20 seconds when the handset is fully charged. (See your phone manual) The phone was made by Thomson Electronics for GE; the manual is available here: .
4) The phone base or handsets are not transmitting or receiving the signals properly. This means that the phone needs repair or replacement. If it is under warranty, contact the manufacturer. Otherwise decide if the phone is worth the repair costs.

If you have no dial tone at the jack where the base is connected, check another phone jack on that line. If you still have no dial tone, find where the phone service comes in. Then open the service box and if the service is fairly new, plug in the RJ-11 test phone and listen for a dial tone. If you can't plug in the phone cord or there is no dial tone, contact your service provider. They will test and fix any outside problem.

If the problem is inside, inspect the visible wires. If you have a DSL filter as part of the inside wiring, check/replace it. If only one jack has a problem, open the faceplate and fix any loose wires. There are two faceplate designs - screw terminals or keystone jacks. For the screw-type, the conductors must be stripped and secured under the screws. For the keystones, the conductors are not stripped but pressed into the terminals with a punch-down tool. This tool is available at many home improvement stores in the wiring aisle. See for a diagram of the wiring.

If the problem is not in a visible part of your wiring, you may want a professional to find and fix the problem. Your telephone provider will be willing to do the work for a fee.

I hope this helps.

My phones say "phone in use", but they are not. Cannot receive calls or dial out.

Whenever I see this issue, I grab an old corded phone as a test phone. The line in use message could be a problem with the phone line or the phone. First make sure that the base has power and try a new phone data cord (RJ-11). Next plug in a test phone to that jack and see if you get a dial tone (preferably with the new data cord).

If you do not get a normal dial tone, try another jack on the line. If you still do not have a dial tone, find where the phone service comes in and open the box. If you have a new service, you'll find an RJ-11 jack in the box. In that case, plug your test phone into the jack. If there is no dial tone or you can't test at the service box, contact your phone company. They will test the line and fix any outside problem.

If it is an inside problem, inspect all visible wiring and open the wall plate if only one jack is bad. There are two standard types of wall plate connections. For one, you strip the conductors and secure them under a screw. For the other, you use a punch down tool to press the conductors (without stripping them) into the right spot in the keystone jack. This tool is available at many home improvement stores in the wiring section. See for a picture of the correct wiring.

If the problem is with your phone only, try to reset it. Take the batteries out of the handsets and unplug the power cord from the base and the wall outlet. Wait a few minutes and then plug everything back in. Make sure that the power brick is warm (getting power) and that the handset batteries are fully charged.

If the reset doesn't help, you should contact the manufacturer. If the phone is under warranty have them repair it. (If it is out of warranty, decide if it is worth fixing.) Most of these phones are not meant to be repaired by the consumer.

I hope this helps.

No dial tone, cannot receive or phone out. Phone

First check to make sure that the phone line is working. Unplug the telephone cord from teh telephone (Do not unplug it from the wall as you will want to make sure the telephone cord is good also) Plug in another phone and see if it works, if it does the problem is the phone, if it doesnt the problem is either the telephone cord, or the wiring in the wall or the jack.

Just bought phone no dial tone i move the setting to pulse

First thing to try is another phone in the wall jack if it doesn't work either you need to call your phone company. If the other phone works, make sure that the telephone is getting power from the AC electrical outlet. Try swapping the telephone cord with another cord. and lastly, unplug the battery from teh handset and plug it back in untill you feel it click into place. Sometimes the new battery connections are pretty tight and may not really be connected even though it looks like it is plugged all the way in.
