Important: 
To listen to the transmission, the mode of the
programmed channel must be the same as that of the
trunking channel (MOT, or ED).
When an ID code is received, the ID list for the bank is
searched, and if found, the text name stored for the ID
appears. If not found, scanning resumes immediately
unless the bank is in open trunking mode.
Note:
 There might be more than one talk group transmit-
ting at a time in some Motorola trunking systems. If you
set the scanner to...

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.
