Previous view 5 BASIC OPERATION ■■Band Scope function The Band Scope function allows you to visually check a specified 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. Strong level Weak level The signal on the 146.060 MHz Band Scope display Center frequency (Example: 146.010 MHz) Sweep marker DDSweep operation qqPush [QUICK] to open the Quick Menu screen. wwPush D-pad(E) to select "Band Scope," and then push D-pad(Ent). D-pad (Ent) () eePush D-pad($) to select the option between "Single Sweep" and "Continuous Sweep." rrPush D-pad(Ent) to return to the frequency display and start sweeping. • A single Sweep checks the specified frequency range only one time. • A continuous Sweep repeatedly checks the specified frequency 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 signal audio. • When the sweeping stops, push [CLR] to cancel the Band Scope function. 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 function. 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.

Depending on the presetting, you may hear the signal audio.
