TROUBLESHOOTING
PROBLEM LIKELY
CAUSES
SOLUTION
The alarm is
not being
triggered by
nearby
cellular phone
activity:
Signal from phone is too weak,
this may be due to close
proximity of cellular base station;
The cellular phone may not
actually be transmitting; unit
may be mounted
on
a metal
surface or there is an
intervening structure which
blocks the signal; unit is not
powered up or batteries are not
installed correctly or have
insufficient power. The alarm
options may be switched off.
The record options may be
switched on.
Increase sensitivity THRESH to
maximum; Check the location of the
Cellphone Detector Plus™ and if
necessary move it to a non metallic
surface and away from intervening
architecture. Check power to the
unit and make sure the alarm
switches are toggled ON and
RECORD switch is toggled OFF. If
necessary, test the unit against other
phones and in other locations.
The alarm is
being
triggered all
the time,
even without
cellular
phones being
present.
Your device is being activated
by mobile phones outside of
your domain or it may be
activated by non-cellular RF
signals either inside or outside
your domain.
Switch PMR to off and / or reduce
THRESH.
Phones on
standby are
not triggering
The alarm.
The unit is
working OK
apart from
this.
Phone signals are periodic
(every few seconds or minutes)
and the RF burst is very short in
duration.
Ensure that the Register switch is
UP. However, just because a phone
is on standby, does not mean that it
is actually transmitting. Registration
signals can be seconds or minutes
apart. Even then, because of their
short duration they are more difficult
to detect.
