4. Press FUNC then 2. The screen displays
the Base, Offset, and Step with the
B in
Base blinking.
5. If necessary, use the number keys to enter
a new Base frequency and press ENT. The
O in Offset blinks.
6. If necessary, use the number keys to enter
a new Offset frequency and press ENT.
The
S in Step blinks.
Note: If you try to program an offset
frequency in the UHF-Hi bands (806-
960 MHz), the scanner ignores the
entry.
7. While the S in Step blinks, repeatedly
press S or T to select the step number:
5.0, 6.25, 10.0, 12.5, 15.0, 18.75, 20.0, 25.0,
30.0, 31.25, 35.0, 37.5, 40.0, 43.75, or 50.0
kHz, then press ENT.
8. Press PROG.
UHF-Hi (806-960 MHz)
To program 800 MHz Motorola trunking:
1. Press PROG then TRUNK to enter the ID
program mode.
2. Press FUNC, then press S or T. The bank
number increases or decreases by one. If
you hold down S or T, the bank number
increases or decreases continuously.
3. If necessary, repeatedly press MODE to
select
“Motorola.”
4. Press FUNC then 3. “NORMAL” appears.
5. Press S or T to select NORMAL or
SPLINTER and press ENT. If you are
uncertain about the base frequency, use
NORMAL.
The base frequency in NORMAL is
851.0125 MHz. The base frequency in
SPLINTER is 851.0000 MHz. . If you cannot
receive with the NORMAL setting, change
to SPLINTER.
EDACS Trunking Setup
EDACS (GE/Ericsson) systems transmit
Talk Group ID data on a dedicated control
channel. Scanning requires clear reception
of the control channel at all times, so EDACS
systems generally have a smaller usable area.
You can manually select the data channel,
but an external antenna can greatly improve
EDACS scanning.
If you are programming frequencies for an
EDACS system, you must store them in the
Logical Channel Number order (usually listed
as LCN#).
Note: For information about saving
frequencies into channels, refer to
“Defining a Channel”
on page 18.
LTR Trunking Setup
LTR systems assign each frequency a Home
Repeater (HR) number and are frequently
programmed with unique ID codes for each
radio. LTR Talk Group IDs are organized in a
specific order, and to scan, you must program
the frequencies in HR order. LTR systems are
used primarily by businesses, such as taxicabs,
delivery trucks, and repair services.
