Replacing a handset
If you are replacing a handset on a system that has the maxi-
mum number of registered handsets (four) or wish to change the
assigned handset number of your registered handsets, you must
first follow the below steps to de-register the handsets, then reg-
ister all handsets again (page 4-5).
To de-register all handsets
Press and hold HANDSET LOCATOR on the main telephone
base E5901/E5902B/E5903B/E5911/E5912B/E5913B/E5914B/
E5921/E5922B/E5923B/E5924B/E6001/6002B/E6012B/E6013B/
E6014B/E3813B until the IN USE light starts to turn on then flash
(about 10 seconds), then release the HANDSET LOCATOR but-
ton.
• Press and release HANDSET LOCATOR again. The IN USE
light will turn off and in a few seconds, all handsets will be
de-registered.
• All handsets will show NOT REGISTERED if de-registration was
successful.
• To re-register the handset to the telephone base, follow the
registration instructions on page 4-5.
NOTES:
1. If the de-registration process was not successful, you may need to reset the
system and try again. To reset: pick up any registered handset and press the
PHONE/FLASH button, then press the OFF/CLEAR button and place the
handset back into the telephone base.

are not being used.
