INSTALLATION
CHOOSING A LOCATION
Select a location that is near a modular
telephone jack and an AC outlet.
Notes:
• Your TAD-799 connects directly to a
modular telephone line jack. If your
telephone wiring does not have a
modular jack, you can update it
yourself using jacks and adapters
available at your local RadioShack
store, or have the telephone com-
pany update it for you.
• The USOC number of the jack to be
installed is RJ11C (or RJ11W for a
wall plate jack).
Caution: The supplied AC adapter was
designed specifically for your TAD-799.
Use only the supplied adapter.

INSTALLING THE
BACKUP BATTERY
The TAD requires AC power to operate.
However, if AC power fails, or you un-
plug the TAD, a 9-volt battery (not sup-
plied) provides backup power so the
TAD can maintain the correct time and
memory information. We recommend
you use an alkaline battery, available at
your local RadioShack store.
Cautions:
• Use only fresh batteries of the
required size and recommended
type.
• Do not mix old and new batteries,
different types of batteries.
Follow these steps to install the battery.
1. Use a flat-blade screwdriver to
unlatch the battery compartment
cover (as shown), then slide the
cover in the direction of the arrow
and lift it off.
