INSTALLING A BACKUP
BATTERY
If AC power fails or you unplug the TAD,
a 9V backup battery (not supplied)
saves the message groups, message
counts, and the settings for the day,
time, and security code. We recommend
you use an alkaline battery, such as Ra-
dioShack Cat. No. 23-553.
Caution:
Always use a fresh battery of
the required size and recommended
type.
1. Use a Phillips screwdriver to remove
the screw on the battery compart-
ment cover, then remove the cover.
2. Snap the battery’s contacts firmly to
the battery connector and place the
battery into the compartment.
3. Replace the cover and secure it with
the screw.
Replace the battery when
Lo
appears.
Cautions:
• Before you replace the battery, be
sure the TAD is properly connected
to AC power. Otherwise, you might
lose any stored information.
• Always remove old or weak battery.
Battery can leak chemicals that can
destroy electronic parts.
• Dispose of the old battery promptly
and properly. Do not burn or bury it.
SETTING THE DAY AND
TIME
To avoid losing the day and time settings
if AC power fails, we recommend you in-
stall a backup battery before you set the
day and time (see “Installing a Backup
Battery”).
Follow these steps to set the day and
time so the TAD can record the correct
day and time when each message and
memo is recorded.
Notes
:
• If you do not complete each step
within 8 seconds, the TAD sounds
four beeps and exits setup. Start
again at Step 1.
• Be sure you set
VOLUME
at the right
side to an audible level so you can
hear the announcement.
