Installing the AT&T Digital Announcer
Applying AC Power
To apply AC power, perform the following steps:
1.
Plug the cord from the power supply into the 10 volt AC
connector on the back panel of the unit.
2.
Plug the power supply into a suitable electrical outlet.
NOTE:
An external power surge suppression unit (such as
an AT&T 147A Surge Protector) is strongly
recommended.
As soon as the unit is powered-up, it begins an internal diagnostic
and initialization procedure. The unit performs this procedure only
if it has been disconnected (without power) for longer than three
hours. During this procedure, the Power LED on the front panel
turns on, and the Battery LED starts blinking rapidly. Next, the M1
LED turns on, and the Mode LED turns red and remains on for the
amount of time allocated for message 1. If you allocated any time
for message 2, the M1 LED turns off, the M2 LED turns on, and
then the Mode LED turns red and remains on for the amount of
time allocated for message 2.
After the unit completes the diagnostic and initialization procedure,
the Mode LED turns off, and the M1 LED starts blinking slowly,
signifying that a message has not been recorded yet. The Battery
LED also starts blinking slowly, indicating that it is recharging for a
period of up to 18 hours. The Battery LED remains on when the
battery is fully charged.
If the blinking pattern or the steady on condition of the Battery LED
2-12
is interrupted with an extended off cycle, the unit is in an Out of
Service condition. If this condition occurs, refer to Chapter 5.
