tune direction, press or . When the scanner nds an active

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 specic frequency, trunking systems
choose one of several frequencies during a 2-way radio transmission
and simultaneously transmit a Talk Group ID that identies 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 dene 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 dene a Trunking Bank:
1. Press PROG, then press TRUNK to enter the ID program mode.
2. Press FUNC, then use or to select a bank.
