channel.
This scanner lets you easily hear both the call and response transmissions for that 2-way radio user and
therefore follow the conversation. For EDACS and Motorola (above 406 MHz range), the scanner monitors
the control channel between each transmission to identify talk groups.
SETTING SQUELCH FOR THE TRUNKING MODE
Your scanner automatically mutes the audio during trunk scanning when it decodes control channel data.
However, we recommend you turn SQUELCH clockwise and leave it set to a point just after the hissing
sound stops. This lets the scanner quickly acquire the data channel.
PROGRAMMING TRUNKING FREQUENCIES
You program trunking frequencies just like non-trunked frequencies, except that you must store the
appropriate mode (MO or ED) with each frequency.
Notes:
• You can store only one trunked EDACS and Motorola channel in a bank. You can, however, mix
conventional channels in a bank.
• If you are programming trunked frequencies for Motorola Type I and hybrid systems, you must first
program the fleet map (see “Programming Fleet Maps” on Page XX).
Follow these steps to program trunked frequencies.
1. Press PROG and select the bank, then press TRUNK to enter the ID program mode.
2. Repeatedly press MODE to select MO for Motorola, or ED for the EDACS (GE/Ericsson) system to scan.
This sets the talk group ID decoding method to be used for the bank.
Notes:
• If you select Non instead of MO, or ED, the scanner does not scan trunked frequencies.
Instead, you see:

• If you programmed a Motorola Type I or Hybrid system, see “Programming Fleet Maps” on Page XX.
3. Press PROG to enter the program mode.
4. Store the trunking frequencies into subsequent channels in the same bank (see “Storing Known
Frequencies into Channels” on Page XX).
5. Repeatedly press MODE to select the trunking mode — MO for Motorola, or ED for the EDACS
(GE/Ericsson) system.
6. Press SCAN to start scanning.
