Scanner will not track a
trunked system

(continued)

The system you are trying
to track is a Type I System,
and the scanner is set to
scan Type II systems.

Set the scanner to receive
Type I trunked frequencies.
See “Scanning Type I and
Hybrid Trunked Systems”
on Page 40.

Scanner will not stop while
scanning a scan list

The IDs you have stored
are not active.

Scan another transmission.

Scanner will not acquire a
data channel

Squelch is not correctly
adjusted.

See “Setting Squelch for the
Trunk Scanning Mode” on
Page 31.

The frequency used for the
data channel is missing.

Add the frequency used for
the data channel to the fre-
quency list. See “Program-
ming Trunked Frequencies”
on Page 32.

Missing replies to conversa-
tions

The system you are trying
to track is a Type I system,
and the scanner is set to
scan Type II systems.

Set the scanner to receive
Type I trunked frequencies.
See “Scanning Type I and
Hybrid Trunked Systems”
on Page 40.

The selected fleet map is
incorrect.

Try another preset fleet map
or program your own fleet
map. See “Scanning Type I
and Hybrid Trunked Sys-
tems” on Page 40.

Not all of the trunk’s fre-
quencies have been
entered.

Enter all of the trunk’s fre-
quencies.

Channel activity indicators
are lighting but no sound is
heard.

The transmission might be a
private or telephone inter-
connect call. The scanner
does not scan these types
of transmissions.

Scan for another transmis-
sion.

The ID is locked out.

Unlock the ID (see “Unlock-
ing a Single ID” on Page 36
or “Unlocking All IDs” on
Page 36).
