3. Press and hold MONITOR switch and then

4. Decide what you want to say. If you intend a
lengthy message (or several messages) the
vehicle engine should be running to maintain the
battery charge.

MONITOR switch to assure that the channel is
not in use.

PTT switch and identify yourself. The XMIT in-

your call. Then, complete your message.
NOTE
Always speak in a normal voice. Hold
the microphone cupped in your hand
and touching your cheek lightly. Speak
across the face of the microphone, not
directly into it. Shouting will actually
reduce the radio range, so do not
speak any louder than normal.

SCAN OPERATION
The SCAN function allows monitoring of up to eight or
sixteen receive channels (depending upon which control
module is being used). The scanned channels may be any
frequency within the frequency band limits of the radio and
may be Channel Guard protected. The radio message will then
be received only if the correct Channel Guard signal is present.
Any channel may be scanned with or without priority
level. One channel may be programmed for Priority 1 (P1)
and another for Priority 2 (P2) with any or all remaining
programmed channels being scanned as non-priority (S).
Receive Scan Rate
The scan rate for the radio will vary depending upon the
number of channels programmed into the scan memory and
whether or not Channel Guard is programmed. For a sixteen
channel radio the scan rate will vary from 1.1 to 4.4 seconds
for non-priority channel and 0.3 to 1.2 seconds for Priority 1
and 2 channels. The scan rate will be faster when fewer
channels are programmed into scan memory.
