Expand your telephone system
The handsets provided with your telephone system are already registered. 
Each handset is assigned a number that displays on the handset. Additional 
handsets registered to the telephone system are assigned in sequential order. 
For instance, if the telephone system already has HANDSET 1 and HANDSET 2, 
the new registered handset is assigned HANDSET 3. After registration, you may 
rename the handsets (see Rename handset on page 16). This telephone system 
accommodates up to 12 handsets.
Add and register a handset
You can add new handsets (LS6405, purchased separately) to your telephone 
system. Each handset must be registered with the telephone base before use. 
When first purchased, each handset displays Put HS on BASE to register. You 
may need to charge the handset before registering it to the telephone base. For 
more details on battery charging, see page 4.
To register a handset:
Make sure the handset is out of the telephone base or 
handset charger and shows 
Put HS on BASE to register. Place the handset you 
wish to register in the telephone base. 
The handset displays Registering...Please wait and the 
red IN USE light on the telephone base turns on. It takes 
about 90 seconds to complete the registration process. 
The handset displays HANDSET X Registered  
(X represents the registered handset number).  
The IN USE light turns off and the handset beeps when 
registration completes.
If registration fails, the system will automatically try to register 
again. If registration fails after the third try, the handset displays 
Registration failed then Put HS on BASE to register. This 
may take up to five minutes to occur.
To reset the handset, remove it from the telephone base. 
When the handset displays Put HS on BASE to register, 
try the registration process again.
After registration, the date and time need to be reset. 
For instructions, see Set date and time on page 13.
