Monitoring
When monitoring, the scanner remains on a single channel.
Note:
Your scanner features a power save circuit that allows
the scanner to “sleep” briefly while waiting for a call on a
monitored channel.
To monitor a channel:
1. Press MAN.
2. Use the number keys to enter the channel number and press
MAN.
To find a frequency to monitor:
1. Press TUNE. The currently-tuned frequency and
*** PAUSED ***
appear.
2. (Optional) Use the number keys to change the frequency and
press ENT.
3. Press PAUSE. The scanner searches for a frequency. To change
the tune direction, press S or T. When the scanner finds an
active frequency, it stops.
4. Press PAUSE to monitor the frequency.
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 specific frequency, trunking
systems choose one of several frequencies during a 2-way radio
transmission and simultaneously transmit a Talk Group ID that
identifies the 2-way radio user. This allows trunking systems to
allocate fewer frequencies to multiple 2-way radio users.
Defining a Trunking Bank
You can define 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).
Note: Trunking banks can contain both trunking and non-
trunking channels. For information about saving frequencies
into channels, refer to “Defining a Channel” on page 17.
To define a Trunking Bank:
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. Press PROG.
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 identified, 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.
