tinued)
An antenna is
not connected or

rectly.
Make sure an
antenna is con-
nected to the scan-
ner.
Error
appears.
Programming
error.
Reprogram the fre-
quency correctly,
including the deci-
mal point.
In the scan
mode, the scan-
ner locks on fre-
quencies that
have an unclear
transmission.
Programmed fre-
quencies are the
same as “birdie”
frequencies.
Avoid programming
frequencies listed
under “Birdie Fre-
quencies” on
Page 51 or only lis-
ten to them manu-
ally.
Scanner will not
track a trunked
system.
The transmission
might not use a
system that can
be tracked by
your scanner.
Scan another trans-
mission.
The data fre-
quency is miss-
ing.
Find the data fre-
quency (see “Pro-
gramming Trunked
Frequencies” on
Page 34).
The system you
are trying to
track is a Type I
system, and the
scanner is set to
scan Type II sys-
tems.
Set the scanner to
receive Type I
trunked frequen-
cies. See “Scan-
ning Type I and
Hybrid Trunked Sys-
tems” on Page 44.
Scanner will not
stop while scan-
ning a scan list.
No IDs have
been stored.
Store one or more
IDs (see “Scan

The IDs you
have stored are
not active.
Scan another trans-
