INSTALLATION
CHOOSING A LOCATION
Select a location that is near both a mod-
ular telephone jack and an AC outlet.
Your TAD-1027 connects directly to a
modular telephone line jack. If the tele-
phone line jack is not a modular jack, you
must update the wiring. You can convert
the wiring yourself, using jacks and
adapters available at your local Ra-
dioShack store. Or, you can let the tele-
phone company update the wiring for
you. The USOC number of the jack to be
installed is RJ11C.
INSTALLING THE
BACKUP BATTERY
The TAD requires AC power to operate.
However, if AC power fails or you unplug
the TAD-1027, a 9-volt backup battery
(not supplied) saves the messages and
the settings for the day, time, and remote
operation security code. We recommend
you use an alkaline battery, such as Ra-
dioShack Cat. No. 23-553.
Warnin
g
:
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 fresh battery of
the required size and recommended
type.
Note:
The TAD cannot answer and
record incoming calls without AC power.
Follow these steps to install the backup
battery.
1. Slide the battery compartment cover
in the direction of the arrow, then lift
off the cover.
2. Snap the battery’s contacts firmly to
the TAD-1027’s connector and place
the battery into the compartment.
3. Replace the cover.
