Appendix
Expand your telephone system
The cordless handset provided with your telephone system is already
registered. Additional handsets registered to the telephone system are
assigned in sequential order. For instance, if you already have HANDSET,
the new registered handset is assigned HANDSET 2 and your first handset is
then renamed as HANDSET 1. This telephone system accommodates up to
12 handsets.
Add and register a handset (optional)
You can add new handsets (TL86009, purchased separately) to your
telephone system, but each handset must be registered with the telephone
base before use. When first purchased, each expansion handset shows
Press [ HOLD] on base for 4 sec, then press [#] on handset after a battery
is installed. Each handset should be charged without interruption for at
least 25 minutes before registering to the telephone base. For more details
on battery charging, see the table on page 12.
To register a handset:
Press and hold HOLD on the telephone base for about four seconds until
it shows Registering...Please wait. Then, release the button.
Press # (pound key) on the handset. Its screen shows Registering
handset... and it takes up to 60 seconds to complete the registration. The
handset and telephone base show HANDSET X Registered (X represents
the handset number assigned) and you hear a beep when the registration
completes.
NOTES:
If the registration fails, the handset shows Registration failed for a few seconds and
then Press [ HOLD] on base for 4 sec, then press [#] on handset. Try the registration
process again.
You cannot register a handset if any other system handset is in use.
You cannot register more than 12 handsets to the telephone base. Registration slots
are full shows on the base screen while you are in step 2.
