• The answering system on your
TAD cannot operate without AC
power. However, you can make
and answer calls on the telephone
without AC power.
INSTALLING BACKUP
BATTERIES
If AC power fails or you unplug the
TAD, four AAA backup batteries (not
supplied) save messages and settings
for the day, time, and security code.
We recommend you use Radio Shack
alkaline batteries.
1. Use a Phillips screwdriver to
remove the screw on the battery
compartment cover, then open the
cover.
Note: The battery compartment
cover is hinged and cannot be
removed from the TAD.
2. Place the batteries in the compart-
ment according to the polarity
symbols (+ and –) marked inside.
3. Replace the cover and secure it
with the screw.
Replace the batteries if the LOW BAT-
TERY indicator turns on while the AC
adapter is properly connected.
Cautions:
• To avoid losing stored information,
be sure the AC adapter is plugged
in and connected to the TAD
before you replace the batteries.
• Always use new batteries of the
required size and type.
• Always remove old or weak bat-
teries. Batteries can leak chemi-
cals that can destroy electronic
parts.
• Dispose of old batteries promptly
and properly. Do not bury or burn
them.
