is used to cover the battery
compartment and also to facilitate wall fixing. To
access the battery compartment locate the four
back cover screws and remove them.
BATTERIES

are fitted according to the polarity diagrams in the
battery case. Then re-secure the back cover. Turn
the power switch to ON. Verify that the unit is
working normally by pressing the TEST/MUTE
button. The alarm should sound.
Low battery
alert:
Green LED will flash every 40 seconds rather
than every 10 seconds, and a buzzer will sound
every 6 minutes. When an external DC source is
used, batteries could still be installed for
emergency back up. If the external power fails or is
removed, the Cellphone Detector Plus™
automatically switches over to battery power.
Caution: damage can result to the battery container
if the unit is dropped with batteries fitted. Avoid
shipping or posting the unit with batteries installed.

mid-right PCB). These are permanent discreet
connection alternatives to the external sockets
located on the base of the unit.

and Audio Out; Pin 3 = Audio Out; Pin 4 = external
9V DC power input; Pin 5 = external 0V power
input.
POWER
is a green LED will blink on every 10
seconds to indicate that the unit is switched on and
