Using additional handsets
You can register up to four 
GAP compliant handsets to 
your Essential Phone base to 
extend your phone system 
without needing to install 
telephone extension sockets 
for each new phone.
You have 2 minutes to 
complete the registration 
process.
If registration isn’t successful 
the rst time, please try again 
incase the base registration 
period ran out of time.
If there are already four 
handsets registered to the 
base, the registration will fail. 
You must de-register another 
handset before you can 
register the new one.
