I have had the above answer phone system for about a year and a half. I have a total of 2 handsets. On 2 recent occasions after being on either phone for about 30 minutes, I hear a beeping noise and then a few minutes later, I lose the connection and the line goes dead.
Does this indicate that both handsets need a new battery? Any other possible causes? I always put the phone back in the charger when not in use.
Many thanks.

Re:
I looked up the battery specs for your phone. They are 3 X 200mah= 600mah battery packs. They should last 8 hrs talk time with the headsets. This style of battery pack in my experience only last about 1 1/2years and sometimes longer and "sometimes" shorter...much shorter. I bet you never had problems when you first got them. Basicly this "battery design arrangment" goes back many years before newer battery technlogy was developed. But designers still insist on using them even today. They are cheap to make.
****Time to replace them with new ones.****
Make sure you follow the mfgs charging instructions:
"After battery installation, place the handsets in their base unit or charger and allow to charge for 16 hours before use. You can keep the battery charged by returning the handsets to their base unit or charger after each use. When the battery is fully depleted, a
recharge takes about 12 hours. Average talk time on a fully charged battery is about eight
hours depending on environmental conditions, standby time is approximately four days."
Good luck

Check if the base power adapter is warm to the touch. If it's cold, then the base has no power. Test if distance between the handsets and the base is an issue by moving closer to the base. Check for any radio interference. Check if the handsets are registered. You may need to de-register them first. Try unplugging the base (power and phone line cord) then remove the batteries from each handset. Wait at least 15 minutes before restoring the power/batteries. If the base has a charging cradle, place one handset in that cradle and wait a few minutes. See if that handset works. Otherwise, try to register one of the handsets and see if it works.
If the problem persists, then the base probably has a problem transmitting or receiving the signals from the handsets. Unless the system is under warranty (one year), you should replace the system. Otherwise, contact Uniden customer support.
I hope this helps. Please add a comment with the model of the Uniden phone if you want directions for registering/de-registering the handsets.
Firstly, unplug the base unit, then remove from this base unit the ethernet cable and most importantly, unplug the telephone line! Then remove the batteries from the 2nd handset. Keep everything unplugged for a few minutes, then plug the power into the base unit, wait 1 minute, then plug in the Ethernet cable and wait 5 more minutes. Do NOT plug in the telephone line just yet. After the 5 minute wait, put the batteries back into the 2nd handset and then follow the registration instructions from the manual (copied below)...
Make sure you have configured the language, country code, and area code of your phone before registering additional handsets.
1. Press "Reg.". Register shall be highlighted. 2. Enter the system PIN (Default: 0000). Use "Clear" to correct typing errors. 3. Press "Enter" to confirm. • Your handset starts searching for the base. 4. Press the top button on the base unit until the two indications turn off.
• If registration is unsuccessful, the signal icon displays steadily.
TIP: IF REGISTRATION FAILED, REPEAT THE ABOVE PROCEDURE.
Like other methods, you must hold down the button on the base unit until the lights STOP blinking. When you have successfully registered your 2nd handset, then plug in the telephone line into the base station. I did the above and it worked! The trick is to be patient and wait the few minutes while everything resets itself.
Problem
My handset displays either LOAD DELTA FILE or LOAD DEFAULT DELTA FILE. What should I do?
Solution(s)
Tip 1 of 2 If the handset is not responding normally, you may need to reset your telephone system. Complete the following steps to reset the telephone system: Step 1: Disconnect the power to the telephone base.
Step 2: Disconnect the handset battery.
Step 3: Wait a few minutes and then reconnect the power to the telephone base.
Step 4: Reconnect the handset battery
Step 5: Wait about one minute for the handset to re-establish a link with the telephone base and then test the phone again.
Unplug main unit and the other unit which is not working then plug back on after few minutes. If its still the same then change battery on hand set. baattery life is only four years
Have the batteries been changed since the system was purchased... 4 years is a fairly good usage for batteries in that type of use. Good news you should have no trouble buying replacement batteries... even walmart has them. Open the back of one of the phones... the battery has a small plug.. pull that out and you will see the part number... about 25 dollars each battery pack... cheaper if you are in the states. One note tho... when you replace the battery pack you need to charge it for at least 12 hours prior to the first usage 24 hours even better.
I had the same problem and my hubby managed to reset the phone by simply unplugging it from the electical network. Just wait for few minutes (the date goes back to 1 Jan 2005), then plug it again and try to dial a number. It should work.
To deregister ALL handsets: Step 1: Press and hold FIND HANDSET on the main telephone base for 10 seconds.
Step 2: When the IN USE light starts to flash, release the FIND HANDSET button.
Step 3: Press and release FIND HANDSET again. The IN USE light will turn off and in a few seconds, all handsets will be de-registered.
Step 4: All handsets will show NOT REGISTERED.
To register a handset (register 1 handset at a time): Step 1: Place the handset in the base unit or a charger that is connected to a power outlet. If PRESS FIND HNDST 4 SEC ON BASE does not appear on the screen after a few seconds, lift up handset and place in base or charger again.
Step 2: On the telephone base, press and hold FIND HANDSET for four seconds. Release FIND HANDSET once the IN USE light comes on.
After
a while the handset will emit a series of tones, the newly registered
handset will be assigned the lowest extension number not previously
assigned to another system handset (1-4) when successfully registered.
Repeat Steps 1 and 2 if the handset does not successfully register to
the telephone base within two minutes.
REPEAT THE REGISTRATION PROCEDURE FOR EACH SYSTEM HANDSET.
Make sure the handsets are not receiving interference from other appliances, cell phones, etc.
IF deregistering does not work .. you will need to reset the entire system Step 1: Disconnect the power to the telephone base.
Step 2: Disconnect the handset battery.
Step 3: Wait a few minutes and then reconnect the power to the telephone base.
Step 4: Reconnect the handset battery
Step 5: Wait about one minute for the handset to re-establish a link with the telephone base and then test the phone again. You will need to set the time and date again after resetting the entire system.
SOLUTION to AT&T Cordless Telephone/Answering System 4 phone set Model E5634B - Cannot answer incoming calls nor does caller ID work on phones.
Unplug the base for a few minutes, plug base back in, remove and reinsert the battery on each phone that does not work, then place each handset in the base for few minutes. Worked for me...all 4 phones can be answered and caller ID works!!! Hope this works for you... :o)
You can connect up to 4 cordless sets (Operating manuals, page 21, states 3 but they really mean 3 in addition to the one packed with the base, for a total of 4). I've head four connected for over 5 years now and they work fine. In your case, try disconnecting the battery of the cordless for at least 30 seconds, then reconnect. You may also want to disconnect the power cable from the base unit for a half minute or so. I found this method to be equivalent to a cold boot, and quite effective in getting all phones to work again after a storm or power outage.
