Beyond the Basics
Adding Optional Accessory
Handsets
Ten Multi-Handset Expandability
Your phone supports up to ten cordless handsets, including any
handsets supplied with your phone. You can now place a fully-
featured cordless handset anywhere AC power is available to
connect the handset charger.
Up to four handsets can be used for outside and/or intercom
calls. For example, you can have seven-way conferencing (one
base, four handsets, and two outside lines) while on an intercom
call using the other two handsets.
Registering Accessory Handsets
If you purchase an 43-144 accessory handset, you need to
register the handset before use. Only one handset can be
registered at a time.
Handsets supplied with the phone are registered to the base
by the factory. When charged, pre-registered handsets display
a handset ID number. Handsets that have not been registered
display the message, MODELS VARY! PLACE HANDSET ON THE
BASE FOR REGISTRATION OR REFER TO OWNER’S MANUAL. (If
an accessory handset has been registered to another base, you
must reset the handset before you can register it to a new base.
See “Resetting the Handsets” on page 33.)
When you register an accessory handset to the base, the handset
ID number will be assigned.
1. Before registering the accessory handset, the battery pack
MUST be charged for 15-20 hours.
2. When the phone is in standby, press the
MENU
soft key on
the base.
3. Move the cursor to select REGISTER HANDSET, and then
press the
OK
soft key.
4. On the handset, press and hold # until you hear a beep.
