AT&T phone model E5634B

I have the above model and I'm having trouble with one of my handsets. You can call out on the handset but for some reason you cannot answer any calls. I have checked the oweners manual and nothing addresses the problem. I tried a new battery and that didn't help either. Any suggestions?

Re: AT&T phone model E5634B

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)

How to register hs

It would help to have the model number of the base ( found on a sticker on the bottom of the base ) and the handset (under the battery) but the following works for many models: Press and hold the "Find Handset" button until the "in use" lamp comes on. Press the
"#" key on the handset, then place it on the base... if it is going to work, in a minute or less it will chirp and announce "handset registered". If it shows "registration failed", the base may be "fully populated" and cannot accept another handset: many models are limited to only 5 handsets. To start over by clearing the base registry, press the "Find Handset" button until the "in use" lamp
lights, then continue to hold "Find Handset" until "in use" begins to
blink. Release, then press again the "Find Handset" button for a moment. The base should chirp, and be ready to register handsets again... try again as above until the maximum is reached. Good luck!

Batteries won't charge

There are a few reasons why a battery won't charge. Make sure that the contacts on the phone and the charging cradle are clean. (Unplug the base or charger.) A pencil eraser is good initial cleaner; electronic contact cleaner sprays are a second option. Remove the battery and check the contacts inside the handset and the battery as well. Next replace the battery pack. If you add a comment with your phone's model number, then I can try to find the correct battery. (Stores like Battery Mart may have a compatible battery.)

The final possible problem is that the charging system is bad. If your phone has multiple handsets, try a different charger. If the phone allows you to add handsets, try getting a new handset. The new handset will come with a new charger. (I've never seen the chargers sold without the handset but you could try Uniden customer service. If the base station is the only handset cradle, you'll probably need to replace the phone if a new battery and clean contacts don't work.

If your Uniden phone is under warranty, contact the company.

I hope this helps.

House phone says to register HS, see manual what do i do

I assume you're asking about a cordless phone? Cordless handsets need to be "registered" to a particular base station. You wouldn't want your handset responding to your neighbor's calls, would you? Would you want your neighbor picking up your calls?

The manual will give you instructions on registering your handset to the base. If you still have trouble, please repost your question, specifying the make and model of your phone.

Here is a direct link to the User's Manual for your phone:

To view the Owner's Manual with Operating Instructions just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the information at the website indicated and the contents of the Owner's Manual.

You may need ADOBE READER installed on your computer to read PDF documents.
You can download this free at WWW.ADOBE.COM if necessary.
Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there, then follow the onscreen instructions to install the software on your computer.

See page 26 of the manual for detailed instructions on HOW TO REGISTER THE HANDSET TO THE BASE.

Basically, the manual reads as follows:

Not registered appears on the handset and it does not work at all.

The handset may be deregistered from the telephone base.
Follow the steps below to register the handset to the telephone base.

1. Remove the handset from the telephone base.

2. Press and hold FIND HANDSET button on the telephone base for about four seconds until the red IN USE light turns on.

3. Then press # (pound key) on the handset.

It displays Registering... and it takes about 60 seconds to complete the registration.
The handset displays Registered for a few seconds and you hear a confirmation tone when the registration process completes.

I hope that was helpful to you, good luck and take care.

I have a phillips CD240 cordless phone, on the screen is flashing SEARCHING and wont make or receive calls.

Hi, I solved this issue this morning. "Searching" means the handset cannot find the signal from its base, and if you check your base, it's more likely than not, dead. In my case, I checked this by pressing any button on the base, i.e. answer phone etc., there was no response (although the handset seems to recharge power fine for some reason).

Therefore, I went and bought a new cheap GAP compatible (binatone 1800 Single at Comet - 14.99). I then set up the base, put it in the registration mode as per the binatone instruction. Then on the Phillips CD245 handset and gone through the above registration procedure... and Voila! It worked.

Now I have a brand new base that came with 1 new handset of its own, and 3 additional CD245 handsets which are all registered with this base. So far, the sound quality is good (no different from the previous genuine set) and they retained all the telephone numbers registered with the handset.

I don't have any high regards to binatone specifically as a brand because our last corded phone system was rubbish and died shortly after 12 months guarantee but to me it looks as if GAP compatible cordless phones have certain life-span however cheap or expensive they are (while handset seem to last much longer). Threrefore, there is more incentive to buy a cheap base new (of any make that are GAP Compatible) then connect your old handset to this base and live on 12 months manufacturer's guarantee and hopefully more. On the web, I saw some comments that are saying GAP Compatible phones and base sometimes do not successfully register each other (despite even being of the same make or brand). Obviously the users make such attempt at her/his own risk but I can confirm that the above combination worked for me.

Just for info, to do the registration successfully, the both base and handset must be in "Registering" mode. First, to get the base in the registration mode, you have to press <page> (a paging function for handset in case you cannot find where they are - usually button that says <page>or speaker with sound symbol on the base) more than 5 seconds, then the base is in the "Register Mode"(though you will hear no beep). You can then go through the procedure you describe on the handset and the handset should beep with assigned number no more than 10 seconds after it flashed "Waiting".

I hope this is helpful.


The above, however, works only if the Base is still functioning.

I have a panasonic cordless phone, model kx-tga820. for some reason both handsets now say that it is busy when i push the talk button. Our other phones are ok. Why?


If you get busy tone in your Panasonic KX-TGA820 cordless phone, it may be due to any one of the following reasons:

1)The called handset is in use.

2)The handset you are calling is too far from the base unit.
Check whether the base unit is not so far from the handset

3)There is no handset registered to the base unit matching the extension number you entered.
Try to re-register the handset to the base unit again, To know details regarding registering and re-registering, please refer page 38 of the manual, which you can download from the link given below

4)Other units are in use and the system is busy. Try again later.
Try to check whether the other units are not using your base unit

You can download manual for your phone from the following link for reference

I can not get the handset to charge. Tried a new battery and all solutios in manual

This happens pretty regularly at my house. The solution is pretty simple. I take the batter out and put it back in and put it back into the cradle.

I have four kids at home and the phones are banged around quite a bit. I think the battery just loses a solid connection to the terminal points.

Now, can someone help me find a way to get my teenagers to implement this fix when they hear the battery beeping because of low battery?
