To use the following troubleshooting guide, locate the problem in the left
column and look for the problem’s possible causes and corrections in the middle
and right columns. Possible causes are listed in the order in which they are most
likely to happen. Check for possible causes in the given sequence to help isolate
the problem.
Problem Possible Cause Correction
No communications. One or more
headsets hear static. The base station is not ON. Turn the base station ON. Make
sure that the power transformer is
plugged into the wall outlet and into
the base station power receptacle. If
the red power light does not come
on, check for power at the wall
outlet. If power is OK, call for
authorized service.
Base station and belt packs not
programmed to same channel. Reprogram base station and/or belt
packs.
The base station is defective. Call for authorized service.
A single belt pack is dead. No
communication to or from customer.
No communications to or from other
belt packs (PAGE or TALK
functions). No static is heard. The belt pack is not turned on. Turn the belt pack on.
The battery is discharged.
Replace the battery with a fully
charged one.
The headset is unplugged or
defective. Call for authorized service.
Belt packs do not go into standby
(silence) when the vehicle leaves the
menu sign. This is normal when an “air switch”
type of vehicle detector is in use. Momentarily press the PAGE switch
to return to standby.
There is a large metal object over
the loop in the driveway (if a loop is
used). Remove the metal object.
Defective vehicle detector. Call for authorized service.
The monitor speaker does not
operate. The base station internal monitor
volume control is turned too low. Increase the monitor speaker
volume setting. (Store manager
only.)
