PERATION
Before activating the scanner, make sure that the Squelch is set to silence the background
noise when no signal is present. Scanning is not possible while the Squelch is open (if noise
or signals are being heard).
Scanning may be started or stopped using the microphone’s [
UP
] or [
DWN
] button. The
following techniques are used for scanning:
Pressing and holding in either the [
UP
] or [
DWN
] button for one second in the
VFO
mode
will cause upward or downward
band
scanning, respectively, to begin.
Pressing and holding in either the [
UP
] or [
DWN
] button for one second in the
Memory
mode
will cause memory channel scanning toward a higher- or lower-numbered
memory
channel
, respectively.
Scanning pauses when a signal opens the squelch, and the decimal point on the display
will blink. You can choose one of three scan-resume modes (described later).
To halt the scan manually, the easiest way is to push the
PTT
switch on the microphone
momentarily (no transmission will occur while you are scanning). The scan may also be
halted manually by pressing the microphone’s [
UP
] or [
DWN
] button, or the [
D/
MR
(
MW
)] key.
In the factory default setting, the scanner sweeps all frequencies while the VFO
mode and all memory channels while the Memory mode. You may change the
sweep range of the VFO mode to ±1 MHz, ±2 MHz, or ±5 MHz, or sweep only those
Memory Channels with the same “first” or “first” and “second” digits of the alpha/
numeric tag as the first channel on which scanning started, using Set Mode items “28
MEM.SCN” and “56 VFO.SCN.” See pages 77 and 82 for details.
