Phone beeps
The battery may need to be recharged.
•
Put the handset into the charging cradle of
the base unit. It may take up to 15 hours to
fully recharge the battery.
•
Your handset may temporarily lose its
synchronization with the base unit due to
radio interference in your area. When this
happens, "OUT OF SERVICE" shows on the
handset display.
•
If you do not wish to hear the beep tone,
you can turn it off. See the KEY TONE
section for more information.
Low battery warning
If you just recharged the batteries, but keep
getting a low battery warning, the batteries may
need to be replaced.
•
Rechargeable batteries gradually lose their
ability to store a charge the older they get.
Simply replace the battery with a new one.
MULTI-HANDSET USE
Cannot register new handset
Sometimes it helps to unplug and then reconnect
your base unit to its AC power source before you
start the registration procedure.
•
You may have already registered 4
handsets to the base unit.
•
If you are replacing a faulty handset, make
sure you have fully removed the faulty one
before registering the new one.
•
If you are still experiencing problems, you
will need to reset all the registrations then
start over.
Cannot dial out
Only one outside call and one intercom call can
take place at the same time. Make sure no one
else is already using the phone; if so, you will see
the EXT IN USE symbol on the handset display
area.
All handsets show "OUT OF SERVICE" and
telephone will not work
Reset your telephone, and then try the registra-
tion process again.
•
If you are still experiencing problems, reset
and then re-register all your handsets one-
by-one.
