SETTING THE SCANNER
TO THE TRUNK
TRACKING MODE
Press
TRUNK
to switch between the
scanner’s conventional and trunk
tracking modes.
SETTING SQUELCH FOR
THE TRUNK TRACKING
MODE
Your scanner’s squelch setting is au-
tomatically adjusted in the trunking
mode, which means you do not need
to manually adjust squelch while
tracking trunked transmissions. How-
ever, the squelch setting can affect
how fast your scanner acquires the
data channel, and, in some instances,
can prevent your scanner from acquir-
ing the data channel at all.
We recommend you set
SQUELCH
to
this position before selecting a trunked
bank.
Note: You can change this setting, if
necessary, to provide better perfor-
mance in your area.
PROGRAMMING
TRUNKED
FREQUENCIES
Before you program your scanner to
track a trunked system, consider the
following:
• Valid trunked system frequencies
range from 851.0000–868.9875 in
12.5 kHz steps.
• You can use any of your scanner’s
banks as either a trunk tracking
bank or conventional scanning
bank, but you cannot mix the two.
• The scanner only scans one
trunked system at a time. Al-
though you can store frequencies
for more than one trunked system
in one of your scanner’s banks,
the scanner only scans the fre-
quencies associated with the first
data channel it finds.
Before scanning a trunked system’s
transmissions, you must store the
trunked system’s frequencies in one of
the banks in your scanner by following
these steps.
1. Hold down
TRUNK
until the scanner
beeps twice.
