To set a default tuning frequency:
1. Press MAN.
2. (Optional) Use the number keys to enter the
frequency number.
3. Press FUNC, then TUNE. The scanner saves
the frequency. For example, if you save
145.31000 MHz, when you press TUNE, the
scanner starts tuning at 145.31000 MHz.
Trunking Setup
Instead of transmitting on a specic frequency,
trunking systems choose one of several
frequencies during a 2-way radio transmission
and simultaneously transmit a Talk Group ID
that identies the 2-way radio user. This allows
trunking systems to allocate fewer frequencies
to multiple 2-way radio users.
Dening a Trunking Bank
You can dene any of the 10 banks as a trunking
bank, but each bank can only scan for one
system: Motorola, EDACS (GE/Ericsson), or LTR
(EF Johnson).
Trunking banks can contain both trunking
and non-trunking channels.
To dene a Trunking Bank:
1. Press PGM, then press TRUNK to enter the
ID program mode.
2. Press FUNC, then use or to select a
bank.
3. Repeatedly press MODE to select a trunking
mode (Motorola, EDACS, or LTR).
4. Press PGM.
Trunking Modes
In Closed mode, the scanner stops only on
transmissions with saved and unlocked Talk
Group IDs. This lets you focus a scan on the
frequencies you have identied, ignoring other
transmissions.
In Open mode, the scanner stops for
transmissions on any unlocked channel. This
lets you search for Talk Group IDs that you can
then save.
While scanning, “–” appears for Closed mode
and “+” appears for Open mode under
the channel storage bank’s number. When
the scanner stops on a channel,”OPEN” or
“CLOSED” appears.
To set Open or Closed mode for a bank:
1. Press MAN.
2. Use or to select a bank.
3. Press FUNC then DELAY. “Bank OPEN” or
“Bank CLOSED” appears.
Motorola Trunking Setup
Motorola systems can allocate as few as ve
frequencies to up to several thousand groups of
users in three categories:
• Type I – User groups are assigned to eets.
To scan, you must program a eet map into
the scanner.
• Type II – The Talk Group ID contains 4 or 5
digit numbers.
• Hybrid – Combines Type I and Type II
formats.
