Registration and deregistration
Adding and registering handsets
3. The screen shows Registering... Please wait
and the IN USE light turns on. It takes up to 90
seconds to complete registration. Then,
HANDSET X Registered appears on the screen,
with HANDSET being the handset name and X
being the handset number (1-12). The handset
beeps and the IN USE light turns off. The handset
is now registered with the telephone base.
If registration fails, the system will automatically try
to register again. If registration fails after the third try,
Registration failed appears on the screen for a few
seconds. This may take up to five minutes to occur.
Please start again from Step 1.
NOTES:
• You cannot register a handset if any other system handset is in use.
• To reset the telephone, unplug the power from the telephone base and the battery
from the handset, then plug them back in.
