1.Press PROG then TRUNK. TRUNK appears and one
or more bank numbers flash.
2. Press the number key (1–10) of the desired target
storage bank. Select one of the trunk systems by
repeatedly pressing 8 or 9 to select a trunking
system type, then press E (SVC). The scanner then
automatically selects the first channel in the
selected bank.
E2-800 is what type of system you want.
3.Use the number keys to enter a valid frequency
within the trunk system, then press E (SVC). BANK
and the bank number, the channel number, and E
(EDACS) or M (Motorola) appears depending upon
the trunk system selected.
Enter channels in this order for the Sarpy System
854.5375
854.2625
859.9875
859.2375
858.9875
858.2375
857.9875
857.2375
856.9875
856.2375
4.Press either PROG or 8 to select the next channel
in the bank.
5. Repeat Steps 3 and 4 until you enter all desired frequencies
in that bank
6.Press SCAN, then SRC to begin searching for the
trunk’s data channel and scan conventional frequencies
at the same time.
As the scanner looks through the frequencies, you
see them on the display. When the scanner finds
the controlling data channel, the scanner begins
trunking.
This should make it track the system and hear the traffic on the system.
As it trunk you should see Talkgroup ID coming when you get that I will look at manual to see how to program ID you want.
There is some encrypted digital talkgroups, just lock those out.
