Troubleshooting

Issue
The scanner is not
working at all.
Cause:
The AC or DC adaptor
might not be connected.
The batteries might be
dead or need to be re-
charged.
If the scanner does not
operate when you con-
nect a DC adaptor, the
DC adaptor socket might
be dirty.
The scanner does not
receive any stations or
reception is poor.
Cause:
Antenna might not be
connected correctly.
Squelch setting might be
too sensitive causing it to
pick up unwanted, partial
or weak transmissions.
Antenuator might be on
so your scanner might
not receive weak signals.
The scanner might need
to be initialized.
Solution
Be sure the adaptor's barrel
plug is fully inserted into
the PWR DC 9V jack. The
center tip of the adaptor's
barrel plug must be set to
positive.
Recharge the rechargeable
batteries or replace the
standard batteries.
Unplug the DC adaptor
from the power source and
clean the socket, or check
the adaptor's internal fuse.
Check the antenna.
Check the squelch.
Check the Attenuator.
Turn the scanner off then
on again, or initialize the
scanner.
