BT gave me solution, which (so far) seems to work: Reset the software of the telephone to default settings... On any handset - 1. Press 'menu' 2. Scroll to 'settings' & press 'ok' 3. Scroll to 'base' & press 'ok' 4. Scroll to 'reset base' & press 'ok' 5. 'System PIN' will be displayed - enter '0000' (unless you have altered the default pin number) 6. Press 'ok' 7. Press 'yes' 8. Switch the main base station off at the power & remove the batteries from all handsets for approximately 30 minutes . This didn't reset my address book (thank goodness) but did reset some other settings, such as time/date, OGM, group ringtones etc.
Press the Menu button and use the up/down arrows to go to Handset Settings followed by OK. In the next menu, set the Ringer Volume (press OK to select) and Ringer Tone as needed, press OK to save the settings. If the base or another handset is in use, wait until the phone is hung back up and try programming the handset again.
Make sure the handset is registered to the base unit. Menu > Handset Settings (OK) > Registration (OK) > HS Registration (OK). Press and hold the Locator button on the base unit until you hear the registration tone. Then press OK within a minute and a half. Wait until you hear a beep and the symbol (Y overlapping a T) stops flashing.
My phone which is 2 months old has incurred the same problem today! I took it back to the carphone warehouse and they are sending it away to be investigated. However a friend of mine wanted the identical phone and by coincidence went into the o2 shop today to upgrade and was told there was a callback on them and none available until further notice! There must be some sort of fault on the handset and probably this is 1 of them.
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.

Hello Majaje68, Have you tried entering the last four numbers of the phone number that phone had as the unlock code yet, that may be your SIM PIN. If that doesn't unlock it, you can try "0000", "1234". etc... If you didn't apply a lock PIN, then it was probably done by your phone provider, in which case it's probably the last four digits of the phone number. Good luck.
OU might need to deregister the hand set first by holding down the red
end (hang up key) and keep it down while holding the # key. If
deregister wont work use base unavailable and yes, you are sure twice.

If you want to register the handset to a different base or
replace a handset with another one, you must first clear the

I have a Panasonic KX-TG6700 base unit and KX-TGA670B handsets. We had a similar problem where we were no longer able to deregister the handset using the handset itself. We wanted to be able to use that slot that the broken phone was still occupyng. The solution that we found in the manual online was to hold down the intercom button for 3 seconds until the "in use" light turned on. Then press and hold the number of the extension you want to deregister until it beeps. At this point the base unit has freed that extension.
