You can register up to five GAP 
compliant handsets to your 
BT2600 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.

 will be 
displayed, press   then 
follow the instructions starting 
from point 4 opposite.
You have 2 minutes to complete 
the registration process.
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, see page 65.
If you’ve bought a BT2600 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 
BT2600 base before it can be used.
