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 a sweep. If the tuning step is set to wide, the
present signal may not be displayed (may be skipped),
even if it is strong signal. Thus we recommend to set the
tuning step to 20 kHz or less to use the Band Scope func-
tion. See page 5-7 for Tuning step selection details.
TIP:
• For the single watch operation within the 144 MHz or 430
MHz band, the displayed frequency's audio can be heard
during a sweep.
- In the AIR band, the displayed frequency's audio can-
not be heard during a sweep, even if the single watch
operation is selected.
• The audio output during a sweep can be turned OFF in
the MENU screen.
