5. Repeatedly press
MODE
to select
the trunking mode (
LT
for EF
Johnson,
MO
for Motorola, or
ED
for the EDACS (GE/Ericsson) sys-
tem).
6. Press
SCAN
. If the scanner’s
receive mode matches the ID
mode,
T
appears and the scanner
scans the frequencies.
Programming Motorola
Trunking Systems (UHF-Lo)
You can program the scanner to re-
ceive transmissions in the UHF-Lo
band (380–512 MHz) of the Motorola
Trunking System. You can receive
these transmissions by:
• Checking the trunking system’s
base frequency and offset fre-
quency. You must program the
system’s base frequency and off-
set frequency to do this.
• Decoding the subaudible data
transmitted with the signals. When
you do this, the scanner might
detect wrong IDs but you can eas-
ily receive trunking frequencies
without programming the base
and offset frequencies.
Notes:
• Base and offset frequencies vary
for each type of trunking system.
You can get information about
these frequencies for the trunking
system you want to scan using
www.trunkscanner.com
, other
Internet sources, or locally-
published guidebooks.
• The scanner automatically de-
codes subaudible data it receives
in the VHF band.
• If you try to enter an offset fre-
quency in the VHF and UHF-Hi
bands (137–174 and 806–960
MHz), the scanner will ignore the
entry.
Follow these steps to program Motor-
ola trunking frequencies in the UHF-
Lo band.
1. Select the bank, then press
PROG
to enter the program mode.
2. Store the base frequency into
channel 00 of the bank you
selected, then store the trunking
frequencies into subsequent
channels in the same bank (see
“Storing a Frequency to a Speci-
fied Channel” on Page 26).
3. Press
TRUNK
then repeatedly
press
MODE
to select
MO
(Motor-
ola).
4. Press
FUNC
then
