Operating Manual
This transceiver contains a wide variety of scanning capabilities. Whether you are in the
VFO mode or one of the memory modes, scanning operation is fundamentally identical in
all configurations, but with the following differences:
In the VFO mode, scanning causes the transceiver to sweep up or down the band,
pausing or halting on any signal encountered;
In the Memory mode, the scanner will scan the programmed memories, and can be
instructed to skip certain memories during scanning;
In the Programmable Memory Scan (PMS) mode, the scanner will scan the band
within user-programmed frequency limits.
Scanning Operation
1. Set the knob to the point where background noise is silenced. A typical set-
ting, for effective scanning operation, will be at 12 o’clock or slightly clockwise from
this position.
2. Set the transceiver into the operating configuration in which you wish to scan (VFO or
Memory; PMS will be described later).
8. Press the key momentarily, then rotate the knob, as needed, until Operating
Function Row [ SCN , PRI , DW
].
3. Press the
(
SCN
) key momentarily to start upward scan (toward higher frequencies
or higher memory channel numbers).
4. Rotate the knob or knob counterclockwise to toggle the scanning direction
downward.
5. The scanner will now cause the transceiver to increment in the chosen direction until a
signal is detected. When a signal is encountered which opens the Squelch, In the FM/
AM modes , the scanner will pause until the signal disappears (at the end of the other
station’s transmission), at which point scanning will resume. While the transceiver is in
the “Pause” condition, the decimal points in the frequency display area will blink. See
“Scan-Resume Choices” on the next page for details of how to customize the resump-
tion of scanning,
In the SSB/CW modes , the scanner will slow down (but doesn’t stop).
6. Press the
PTT
switch on the microphone to cancel scanning.
You may also press and hold in either the

or
[

key on the microphone
for 1/2 second to initiate upward or downward scanning, respectively, if Menu
