78 Using additional handsets
You can register up to five GAP
compliant handsets to your
BT4600 base to extend your
phone system without needing
to install telephone extension
sockets for each new phone.
If a handset becomes
un-registered it will need to be
registered to the base again.
Please register this handset will
be displayed, select
OK then
follow the instructions starting
from point 4 below.
You have 2 minutes to complete
the registration process. After 2
minutes the In use light on the
base will stop flashing.
If registration isn’t successful
the first time, please try again
incase the base registration
period ran out of time.
If there are already five
handsets registered to the
base, the registration will fail.
You must de-register another
handset before you can register
the new one.
If you’ve bought a BT4600 multiple pack, any
additional handsets come pre-registered to the
base. However, if you purchase an additional
handset separately, you must register it to your
BT4600 base before it can be used.
Register an additional handset
1. Select Menu, scroll to display Settings and
press OK.
2. Press to display Registration and press OK.
3. Register handset is displayed, press OK.
4. Press and hold on the base until you hear a
beep and the In use light starts to flash.
5. The handset will display Registering handset...
to indicate the base is in registration mode. If the
system PIN is not 0000 then you will be prompted
to enter it, then select OK.
6. Once registration is successful the handset will show
Handset x registered (with X being the assigned
handset number). The handset will then synchronise
data with any other registered handsets, e.g. contacts,
speed dials and handset names.
