Hi,
Try the following:
1/ Make sure the power cord is securely plugged in at the base and that it's powered on ie: light is on and working etc..

2/ Reset the telephone base. Unplug the electrical power. Wait for
approximately 15 seconds, then plug it back in. Allow up to one minute for the cordless handset and telephone base to reset.

3/ Place the cordless handset in the telephone base for one minute to allow the cordless handset and base to synchronize.

Remove then replace the batteries from the hand set. You should now get dial tojo.

My E2562 handset 1 would not detect base and displayed D51A PD whenever I tried to manually register it. This fixed it:
1. Remove battery from handset.
2. Unplug base and unplug phone connection(s). Wait 30 seconds.
3. Plug in base.
4. Plug in phone connection(s) to base.
5. Put battery back in handset. Handset 1 should then auto register with base.

If the handset has previously worked with the base - press the hangup button and the # key at the same time on the handset for five seconds and follow the prompts to deregister the handset. (System reset - deregister HS - which handset) It will tell you that the handset is deregistered. Then put the handset onto the base and it will register the handset.

Had this problem myself today, emailed binatone and they sent me this - and it worked!

You need to press and hold handset locator button on base unit till starts bleeping, on handset press menu, up arrow to register, press ok, press 1 for base unit, then 0000 for pin code, press ok, it will say wait, press ok again

Cheers

This is due to the base unit losing power and needs the clock resetting.
The handsets retain their clocks under battery power so this is a little misleading.

To reset the base unit clock:
- press the OK key
- press the 'down' arrow twice until "DATE/TIME" is displayed.
- press the OK key again, this will display the year. Enter the correct year on the handset numeric keypad and then press OK. (Only the last two digits of the year need to be entered).
- The date is then displayed in MM/YY format, enter the correct date on the handset numeric keypad and then press OK.
- The time is then displayed, enter rhe correct time on the handset numeric keypad and press OK.
- The handset then beeps and displays "SAVED".
- Press the "C" button and replace the handset on the base unit.

The base unit should now stop flashing "CL".

deregister headsets and then run register again

I reviewed the user guide for that model, and I only see that it is an answering machine. I may indeed be wrong, but is there a chance you have a different model unit? Regardless of the model, normally you have to put the base in registration mode simultaneously when the handset it put in registration mode like you were doing before. If you do not have the user guide you can join Beoworld.org for $27 a year and download it for "free". I am curious to know if you have a different model or if you can register cordless handsets to the 1200. Maybe you can post an update. Just learning this model myself. Good Luck

document.write(parent.prscreen) Try this to get it working. Relocate the handset(s) closer to the main base.

Check for any lights on the base including charge, intercom, and channel lights (if applicable to the model).

Re-cradle the handset on the base for 15 seconds. Lift the handset and press PHONE.

Unplug the AC adapter from the main base unit and take out the battery from the handset. Leave it unplugged for 15 seconds. Plug the handset battery in and re-cradle the handset. Plug back the AC adapter in and wait for 15 seconds.

6. Enter the 15-digit Base ID code using the number keypad.
