INSTALLING A BACKUP
BATTERY
If the AC power fails or you unplug the
TAD, a 9V backup battery (not supplied)
saves the messages, time and day set-
tings, and the CBT and remote opera-
tion security codes. 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 re-
move the screw on the battery com-
partment cover, then remove the
cover.
2. Snap the battery’s contacts firmly to
the battery connector and place the
battery in the compartment.
3. Replace the cover and secure it
with the screw.
Replace the battery when
Lo
appears.
Cautions:
• Always remove an old or weak bat-
tery. Batteries can leak chemicals
that can destroy electronic parts.
• Dispose of the old battery promptly
and properly. Do not bury or burn it.
• To avoid losing stored information,
be sure the AC adapter is plugged
in and connected to the TAD before
you replace the battery.
