Trunking Setup
LTR systems use a Home Repeater as part of
their Talk Group ID.
Note: For information about saving
frequencies into channels, refer to
“Defining a Channel”
on page 18.
To save a correct Home Repeater:
1. Save the LTR channels in any order.
2. Set the bank to Open mode.
3. Manually select LT channels and watch the
LTR data on the display.
Your scanner displays the LTR Talk Group
ID and a number preceded by
“R.” The “R”
number is the Home Repeater number for
the transmission.
4. The assigned Home Repeater channel
must equal the Home Repeater number.
For example, R12 must be programmed
into Channel 12.
Searching for Talk Group IDs
If you tune the scanner to an active Motorola
control channel, the Motorola System ID and
the approximate control channel message
decode success rate appears. This helps you
identify the system and the reception quality.
When the scanner decodes control channel
data from a Motorola system, COTRL appears
on the display.
To search for Talk Group IDs:
1. Set the bank to Open mode.
2. Press SCAN. The scanner scans through
all unlocked channels in the active banks.
3. When the scanner stops on a transmission,
press TRUNK. The scanner displays the ID
location:
Sub-bank. ID Location
0-4 00-29
Example: 2-01
Note: If the ID has already been saved,
“ID was saved” appears. If you try to
store more than 150 talk group IDs in a
bank,
“Memory Full!” appears.
Saving a Talk Group ID
Each of the 10 banks contains 5 sub-banks
that each hold 30 Talk Group IDs. (You can
save up to 1,500 Talk Group IDs.) When the
scanner receives a trunked transmission, it
searches the associated sub-bank for the
Talk Group ID to decode data for Motorola,
EDACS, and LTR systems.
To define a Talk Group ID:
1. Press PROG, then press TRUNK to enter
the ID program mode.
2. Press FUNC, then use S or T to select a
bank.
3. Repeatedly press MODE to select a
trunking mode (Motorola, EDACS, or LTR).
4. Repeatedly press TRUNK to select the
sub-bank.
5. Press S or T to select the location where
to store the Talk Group ID.
6. Use the number and decimal point keys to
enter the Talk Group ID:
