Setting Squelch for the Trunking Mode

Your scanner automatically mutes the audio during trunk scanning when it decodes control channel data. Howev- er, 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 the same as non- trunked frequencies, except that you must store the ap- propriate mode (MOT or ED) with each frequency.

Notes:

•You can scan only one type of trunked frequency, either EDACS or Motorola in a bank at one time. You can, however, mix conventional channels and frequencies 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 56).

•If you are programming frequencies for an EDACS system you must store them in the Logical Channel Number order (usually listed as LCN#). For exam- ple, LCN1 would go into channel 01 for the current bank, and LCN2 would go into channel 02.

Follow these steps to program trunked frequencies:

1.Press PGM and press (or hold down) 8 or 9 to select the bank.
