Press and hold FIND HANDSET on the main telephone base for four seconds.

Press and release FIND HANDSET 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.
To register a handset (register one handset at a time):
Place the handset in the telephone base or a charger that is connected to a power outlet. If

After a while, the handset will emit a series of tones. The newly registered handset will be
assigned the lowest handset number not previously assigned to another system handset when
successfully registered. Repeat steps 1 and 2 if the handset is not successfully registered to
the telephone base within two minutes.
Repeat the registration procedure for each system handset.
