What pin no . Do i need to register my stratus 1500 triple phone

According to the user manual for the phone, the default PIN for remote operation is 000000000 123. To access the second phone register, you may need to enter this PIN when prompted. If you have forgotten your PIN, you can set a new one by following the instructions in the user manual . BINATONE SYMPHONY 2210 CORDLESS TELEPHONE USER MANUAL ' ManualsLib

Do you mean the BT Stratus 1500 cordless phone? If so, the manual is available from the product support page: http://bt.custhelp.com/app/answers/detail/a_id/12318/~/bt-stratus-1500 . The direct link to the manual is https://btbusiness.custhelp.com/ci/fattach/get/223691/1232386725/redirect/1/filename/BT_Stratus_1500_User_Guide.pdf .

I hope this helps.

It needs to be re-registered to the base, if I knew which Binatone phone you had I could have advised. Either comment to supply the model name or call 0845 345 9677 (Binatone Helpline).

BT will not register despite no change of mode. handset has become obsolete

unplug the base and press the register button. (it's the round one to the left of the minus button) holding the register button plug the base in and continue to hold the register button for at least two seconds. you should hear a beep. the pin has been reset to 0000.

i have sort of same problem! I recently bought Panasonic KXTG7223E TRIPLE TAM DECT Cordless Phone.
I have tried to register one of the hand set to the base unit but funny enough it has been regitered to my neibour's phone! I have tried to deregister it but does not let me! can any body help please?
