Question about Panasonic KX-TG2740 Cordless Phone

1 Answer

I have 3 of these handsets and none of them will hold a charge, two of them quit at the same time after a power outage. We can still use the base as a peaker phone and the answering machine still works along with the radio/alarm base in another room.

The transformer (little box that plugs into wall) probably got hit with a power surge and are not giving the charger base enough power to charge the batteries or the batteries are old enough that they cant hold a charge. I am betting on the transformers though. you can test out one by going to a electronics parts store (like radio shack) and getting a replacement transformer take one of you old ones with you (it should be under $10) and if it charges your phone you know what the problem is if not try a battery you can buy them online for about $9.
hope that helps

    Sorry I forgot about this , if your handsets are still working you proably just need to re authenticate them to the base set look under the menu fuction on the base or hanset if it doesnt have one take the battery out of handset close to base wait a moment and put it back in and it should see it.

How do I link handset to base after power outage CS6529-3


You set the cordless phone back into the charging base. After a few seconds (longer if in need of a charge), the cordless will register with the base establishing the connection required to place and receive calls.

Uniden dwx207


When a handset is reading "Searching", it can't communicate with the base. First, check if the base station is plugged into a live outlet. (Try plugging the base into a different outlet or making sure that the circuit breaker hasn't popped. I had a cordless phone base plugged into a UPS. During an extended power outage, the UPS was turned off. The phone didn't work until someone noticed and turned the UPS back on.) Move closer to the base station.

If this was an extra handset purchased later, make sure it is compatible with the base station. The Uniden DWX207 works with the DECT1500, DECT2000 and DECT3000 series bases. Register the handset with the base. The registration procedure depends on the base station. If the base unit has an LCD screen, with the phone in standby, press Menu/Select and press the down arrow to reach "Register Handset". Then press Menu Select again. (If the base doesn't have an LCD screen, unplug the power cord. Then hold the Find HS or Find button as you reconnect the power cord until the Charge/In Use light starts to blink.) Then press the # key on the handset before the registration period ends.

Make sure that you haven't exceeded the number of handsets for your base. You may need to de-register all handsets and then re-register them.

If no handsets will pair with the base, replace the base unit. The transmitter or the receiver aren't communicating properly with the handsets.

I hope this helps.

Hello
Connect the phone line and power UP the base unit. Place the handset on base to get charged. It must reset automatically when you place the handset on base to charge. If not; resetting both handset and base unit is necessary.
Resetting the Handset

You may need to reset your handset in the following instances:

You lose a handset and purchase a new one. When you try and register to your existing base you get registration

failure.

You are unable to register any handsets to the base.

You had a base which needed to be exchanged by the manufacturer. When you register your existing handsets

to the base, the handsets say #3 and #4, but you only have 2 handsets.

When you are instructed to by the one of the manufacturer's call center representatives.

To reset, do the following:

Press and hold [ ] and [#] for more than 5 seconds. Select DEREGISTER HS.

WHICH HANDSET? appears. Select the handset that you want to de-register, and press the OK soft key.

DEREGISTER HS appears. Select YES, and press the OK soft key.

ARE YOU SURE? appears. Select YES, and press the OK soft key. You will hear a confirmation tone. The

handset will clear its registration information from the base, and then delete its own base information.

MODELS VARY! PLACE HANDSET ON THE BASE FOR REGISTRATION OR REFER TO OWNER'S MANUAL. To

re-register the handset to the base (see page 25).

If the handset cannot contact the base, it will display OUT OF RANGE. Make sure the handset is in range of the

base and the base is connected to power.

Note: It is also possible to reset the handset back to its original factory settings. All changes including Caller ID information

will be erased. For more information on resetting the handset back to factory settings and when you need to

do this, see www.uniden.com or call our Customer Service Hotline. See back cover page for contact information.

Resetting the Handset without the Base

If your original base is not available for some reason (for example, it is lost or somehow incapacitated), you can still

reset the handset and use it with another base.

Press and hold [ ] and [#] for more than 5 seconds.

Move the cursor to select BASE UNAVAILABLE and then press the OK soft key.

BASE UNAVAILABLE appears.

Move the cursor to select YES, and then press the OK soft key. ARE YOU SURE?

appears.

Move the cursor to select YES, and then press the OK soft key. You will hear a confirmation tone. The handset

will delete its own base information without trying to contact the base. When the base information is deleted,

the handset displays MODELS VARY! PLACE HANDSET ON THE BASE FOR REGISTRATION OR REFER
TO OWNER'S MANUAL. Register the handset to the new base (see page 25). of its user manaul.
OK.

ADDING HANDSET SAYS OUT OF RANGE


A search of Uniden support only said to call 1-800-297-1023 with handset registration issues. The rep picked up quickly and walked me through the reset procedure. Here it is step-by-step:

1. Remove battery
2. Hold down the * and # buttons and reinsert battery. You should hear a long beep. If not retry. (This is a bit awkward but hold the handset upside down and it's workable)
3. Screen will be blank. Immediately press the right soft menu button.
4. Screen will report that EEPROM is clearing and then state EEPROM Clear Ok
5. Remove battery (yes again)
6. Reinsert battery (this time there's no need to hold down any buttons)
7. Handset will reboot with Welcome screen and then state that phone must be registered (this is the status a handset should be in from the factory)
8. Place handset on base and it will register as normal

Handset has message Out of Range even though it is fully charged on on the handset.


The handsets are reading out of range because they have lost connection with the base. This happens mostly during peak power demands or power outages, but can also happen when the phone is unplugged for any amount of time. This can also cause, at times, the answering machine to stop picking up calls. To remedy this issue, reset the phone system. Please follow the instructions below:
To reset the phone:
1. Disconnect the power adapter, phone line, and remove all batteries from the base and all handsets. Leave it disconnected for 30 seconds to reset the base.
2. Place the batteries in the handsets first and then plug in the power adapter and phone line. Do not place the batteries back in the base yet.
3. Put the handset in the charge cradle.
4. It may take up to 1 minute for the "Out of Range" to clear from the display.
5. Once the "Out of Range" is cleared from the handset place the back up batteries back into the base.

Uniden dect6.0 handsets do not operate


I am writing for my Mum, who is 99. We live far apart, so it is a bit difficult to fix her problem. She had a new Uniden DECT 60 (?) installed in early July. It seemed to be working fine when we left her, but she says it only rings twice before going to voice mail. She says it has always been like that. How can we fix this for her even though we live at a distance?.

Base phone handset #1 holding charge


The base unit should not need a charge. It should be powered by the plug in adapter. It may have a battery to keep operation for a short time in a power outage. The adapter may be loose, the adapter could be broken or the plug in the phone may be broken.
