Backup battery installation

Install three AAA non-rechargeable batteries (not supplied) so
that your telephone can still operate in the event of a mains
power failure.
WARNING: Disconnect the telephone line cord from the base
when replacing back-up batteries.
1. Press the large tab on the backup battery compartment
cover. Then pull to open.
2. Place three AAA batteries into the compartment, matching
the polarity engravings.
3. Replace the backup battery compartment cover. Push the
large tab until it locks securely.
Note: Under normal usage conditions, the three AAA non-
rechargeable batteries should last approximately 6 months.
Battery life depends on the frequency and duration of mains
power failures.
