INSTALLATION
INSTALLING A BACKUP
BATTERY
The TAD-764 requires AC power to op-
erate. However, if AC power fails or you
unplug the TAD, a 9-volt backup battery
(not supplied) saves the messages and
the settings for the day, time, and re-
mote operation security code. We rec-
ommend you use a RadioShack
alkaline battery.
Warning: If the TAD’s modular line cord
is already connected to the telephone
line jack, disconnect it before you install
the backup battery. This reduces the
risk of electric shock.
Caution: Always use a new battery of
the required size and recommended
type.
Note: The telephone operates normally
during a power failure; however, the
TAD cannot answer or record incoming
calls without AC power.
Follow these steps to install the backup
battery.
1. Place a flat-bladed screwdriver
under the tab on the battery com-
partment cover, pry open the cover,
then lift it off.
2. Snap the battery’s contacts firmly
to the TAD’s connector and put the
battery in the compartment.
3. Replace the cover.
After the power is connected (see
“Mounting the TAD” on Page 7), when
the battery is weak or not installed, the
ANSWER indicator flashes. If you are
replacing a weak battery, be sure the
AC adapter’s cord is plugged in so you
do not lose the TAD’s stored informa-
tion.
Caution: Dispose of the old battery
promptly and properly.
