BASIC OPERATION

■ Band Scope function

The Band Scope function allows you to visually check a spec-
ified frequency range around the center frequency.
Example: The tuning step is set to 10 kHz, and a
strong signal is received on 146.060 MHz.

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.
