Operation
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.

Operation
1.
Set the
SQL
knob to the point where background noise is silenced. A typical setting, for
effective scanning operation, will be at 12 o’olock or slightly clockwise from this
position.
2.
Set the transceiver into the operating configuration in which you wish to scan (VFO or
Memory: PMS describe later).
8.
Press the [
F
] key momentarily, then rotate the
SEL
knob, as needed, until Operating
Function Row [
SCN
,
PRI
,
DW
].
3.
Press the [
A
](
SCN
) key momentarily to start upward scan (toward higher frequencies or
higher memory channel numbers).
You may also press and hold in either the [
UP
]
or [
DWN
]
key on the microphone for ½
second to initiate upward or downward scanning, respectively, if Menu #37 (MIN
SCAN) set to “ON.”
4.
Rotate the
DIAL
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, the scanner
will pause until the signal disappears (at the end of the other station’s transmission), at
which point the scanner 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 page ?? for details of how to customize the resumption of scanning.
6.
Press the
PTT
switch on the microphone to cancel scanning.

Among the memories you have programmed, there may be some stations which you do not
wish to scan. For example, weather broadcasts (which are transmitted continuously) will
cause the scanner to stop, and such channels may be skipped so as to avoid this
inconvenience.
To remove a channel from the scanning loop:
1.
Press the [
F
] key momentarily, then rotate the
SEL
knob, as needed, until Operating
Function Row [
MW
,
MC
,
TAG
].
2.
Recall the memory channel to be skipped.
3.
Press the [
B
](
MC
) key momentarily. The “hyphen” in the memory channel number
changes to “dot”; this shows that this channel is now not included in the scanning loop.
4.
Repeat steps 2 and 3 as many times as necessary to skip all the channels you do not
wish to scan.
5.
Initiate memory scanning, you will observe that the channels you marked to be skipped
are not included in the scanning loop.
6.
Press the
PTT
switch to stop the scan; you may now use the
SEL
knob to step through
the channels manually - one at a time - and you will observe that the “Skipped”
channels are, nonetheless, available for recall by manual means.
7.
You may restore a previously-skipped channel to the scanning loop by selecting the
channel manually, then pressing the [
B
](
MC
) key momentarily so that the “dot” changes
