VFO/Memory Scan
1. Rotate the
[
SQL/RF GAIN
]
knob just to the point
where the noise is silenced and the “ ” indi-
cator on the display turns off.
2. Press the
[
PMS/SCAN
]
key to initiate upward
scanning (toward higher frequencies or higher
memory channel numbers).
3. If you want to change direction of the scan while it
is underway, rotate the
[
MAIN DIAL
]
knob one click
in the opposite direction (in this case, one click
counter-clockwise). You will see the scanner re-
verse direction and scan down in frequency.
You may change the direction of the scanner by
pressing and holding the microphone’s
[
UP
]
/
[
DWN
]
key for one second, if you are using the
optional MH-31A8J Hand Microphone or MD-
100A8X Desktop Microphone.
4. In FM/AM mode, when the scanner encounters a
signal strong enough to open the squelch, the
scanner will halt for five seconds, after which scan-
ning will resume.
In the SSB/CW and SSB-based Data modes,
when the scanner encounters a signal strong
enough to open the squelch, the scanner will step
across the signal very slowly, giving you time to
stop the scan, if you like.
5. To stop the scanner, press the
[
PMS/SCAN
]
but-
ton or PTT switch.
ADVICE:
You may select the manner in which the scanner re-
sumes while it has paused on a signal, using Menu
Item “SCN RES” The default “5Sec” setting will cause
the scanner to resume scanning after five seconds;
you may change it, however, to resume only after the
carrier has dropped out, if you like See page 83.
During Memory Group operation, only the channels
within the current Memory Group will be scanned.
