Replacing a handset
If you are replacing a handset on a system that has the maximum number of 
registered handsets (eight) or wish to change the assigned handset number of 
your registered handsets, you must first de-register the handsets, and then re-
register all handsets again.
De-registering a handset
A handset must be de-registered first before it can be registered to another 
telephone base. To de-register a handset, perform the following procedures on 
the handset:
• Press the 
CENTER NavKey   on the handset to bring up main menu.
• Press the UP or DOWN NavKey   or   four times for settings. 
• Press the CENTER NavKey   to enter into settings menu.
• Press the UP NavKey   once or DOWN NavKey   seven times to select 
delete registration.
• Press the CENTER NavKey  and you will be prompted to select YES/NO
for handset de-registration.
• Press the softkey YES to proceed with de-registration or NO to cancel.
• After pressing the softkey YES, the screen will remain blank for a while.
• When the screen shows Not Registered, the de-registration process is com-
plete. There will not be a confirmation tone.
• If you have to de-register more than one handset, but not all, at one time, 
please repeat the above steps for each handset to be de-registered.
De-registering all handsets
To de-register all the handsets currently registered to the telephone base, 
perform the following procedures on the telephone base:
• Press 
SELECT/MENU.
• Press VCID twice to reach the Base Settings option.
• Press SELECT/MENU.
• Press ^DIR once to reach the Delete Handsets screen.
• Press SELECT/MENU.
• Display shows Del Registration of all handsets. 
• Press SELECT/MENU to confirm.
