I can fix this. [email protected]

how do I register my cordless sony phone

A Microprocessor Problem, beyond ecconomical repair.

AL

After 4 handsets are added to a base it will not allow you to add any more. I fixed them at Sony and I have the procedure to add a handset manually.

AL

Lightning Strike near your phone line caused a optical coupler in the phone to burn up. A simple fix with the part. When I worked for Sony I fixed many in Lightning Zones.

OR

If the base any water damage it will do the same thing.

AL

Try resetting the phone.
There is a pinhole in the back of the phone to reset it, you will need to use a pen or skewer to depress the button. If this does not work please let us know.

SORRY TO BE REDUNDANT BUT DID YOU HAVE PHONE IN STAND BY AND NEAR BASE.
THEN PRESS PGM
THEN INTERCOM
THE SCREEN SHOULD SAY ENTER SYSTEM ID
ENTER THE 10 DIGITS SYSTEM ID ( THIS NUMBER IS ON A STICKER ON THE BOTTOM OF THE BASE PHONE)
THEN PRESS PGM.
MAKE SURE YOU ARE PUTTING THE CORRECT ID NUMBER IN THE PHONE
I HOPE THIS HELPS

The weakness with the handsets was that women using hand lotion or hair gel can get it on the front of the keypad. It then works it's way to the back side of the rubber keypad. The oil gets on the powder carbon on the keypad. The Carbon shorts the copper on the phone to activate the #1 or #2, etc. When the oil mixes with the carbon the key no longer works. I replaced many keypads until Sony Supplies ran out.... A cheap home fix would be to open the handset and clean the #1 key and the circuit board. You can try the keys but if they don't have any carbon on them you can buy liquid carbon at Electronic Stores OR just paper punch a circle of alumimum foil. Glue the foil on the key with thin glue. Works....
