My phone says "PLACE HANDSET ON MAIN BASE

Is the handset you are trying to register de-registered? if not it will not register to another base until it is.first de-registered.
To de-register the handset do the following-
With a charged battery in the handset Enter *331734# then without pause Press and Release the Menu Select Button. You will hear a Beep. Handset would then be De-registered..
Then place the handset on the Main Base cradle and follow the instruction that come up on the handset display.if the handset still does not register then most likely the base memory is full and will have to be re-set .
To re-reset the Base:- Remove any handset from the main base cradle. Then Press and Hold the Locator or find HS or handset Locator button until the IN USE light comes on and begin to flash then release it and immediately with out pause press and release it again. That will re-set the base memory. All your handset will then be de-registered and will to be re-registered. Place each handset to be re-registered on the Main Base cradle and follow the instructions on the the handset display and they will register.

Welcome to Fixya
Dear USer
Place your Extension Phone Near to Main for Few times Until it Beeps.OR it Ask for Registration like Please Register or Something like that.Follow the Steps carefully to Register it...Then Check it for Dial tone to Confirm.Some phones may display that the handset needs to be registered. If this appears-Move the handset near to base/main unit & press the "Prog/Mute". Next, press the "Pager" button on the base unit .Then press the "Prog/Mute" button on the handset again to complete the registration.
Hope you got it....Thanks for Connecting FixYa

Handsets that have not been registered display.

Before registering the DSS7905 accessory handset, the battery pack MUST be charged for 15-20 hours.
To register the DSS7905 handset:

Place the handset in the telephone base charging cradle to begin registration.
During the registration process, HANDSET REGISTERING will appear in the LCD. When REGISTRATION
COMPLETE. is displayed; the handset has been registered to the base. If REGISTRATION FAILED. appears,

VERY IMPORTANT: BOTH HANDSETS MUST BE REGISTERED TO THE
