About the sweep steps:
The specified tuning step (in VFO mode) or programmed
tuning step (in memory mode) is used during sweep.
If the tuning step is set to wide, the present signal may not
be displayed (may be skipped), even that is strong signal.
Thus we recommend to set the tuning step to the 20 kHz
or less to use the Band Scope function.
See page 5-5 for the Tuning step selection details.
• For the single watch operation within 144 MHz or 430
MHz band, the displayed frequency’s audio sounds dur-
ing a sweep.
- In the AIR band, the displayed frequency’s audio does
not sound during a sweep, even if the single watch op-
eration is selected.
• The audio output during a sweep can be turned OFF in
the MENU screen.

D Sweep operation
Push [QUICK] q to open the Quick Menu screen.
Push D-pad( w ) to select “Band Scope,” and then
push D-pad(Ent).
Push D-pad( e ) to select the option between “Single
Sweep” and “Continuous Sweep.”
Push D-pad(Ent) to return to the frequency display r
and start sweeping.
• A single Sweep checks the specied frequency range
only one time.
• A continuous Sweep repeatedly checks the specied fre-
quency range.
• Push D-pad(Ent) to stop sweeping and push again to
restart it.
• When the sweeping stops, rotate [DIAL] to move the
sweep marker to a detected signal; you can hear the sig-
nal audio.
• When the sweeping stops, push [CLR]
to cancel the
Band Scope function.
Center frequency (Example: 146.010 MHz)
Example: The tuning step is set to 10 kHz, and a
strong signal is received on 146.060 MHz.
Example: Continuous sweep on 146.010 MHz
While continuously
sweeping
When the sweeping stops,
rotate [DIAL] to move the
sweep marker to a detect-
ed signal; you can hear
the signal audio.
