5 BASIC OPERATION5-12■ Band Scope functionThe Band Scope function allows you to visually check a spec-ified frequency range around the center frequency.Band Scope displaySweep markerStrong levelWeak levelThe signal on the146.060 MHzAbout the sweep steps:The specified tuning step (in VFO mode) or programmedtuning step (in memory mode) is used during sweep.If the tuning step is set to wide, the present signal may notbe displayed (may be skipped), even that is strong signal.Thus we recommend to set the tuning step to the 20 kHzor 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 430MHz band, the displayed frequency’s audio sounds dur-ing a sweep.- In the AIR band, the displayed frequency’s audio doesnot sound during a sweep, even if the single watch op-eration is selected.• The audio output during a sweep can be turned OFF inthe MENU screen.MENU > Sounds > Scope AF Output (p. 16-81)D Sweep operationPush [QUICK]q to open the Quick Menu screen.Push D-pad(w ) to select “Band Scope,” and thenpush D-pad(Ent).D-pad(�)(Ent)Push D-pad(e ) to select the option between “SingleSweep” and “Continuous Sweep.”Push D-pad(Ent) to return to the frequency displayrand start sweeping.• A single Sweep checks the specified frequency rangeonly one time.• A continuous Sweep repeatedly checks the specified fre-quency range.• Push D-pad(Ent) to stop sweeping and push again torestart it.• When the sweeping stops, rotate [DIAL] to move thesweep marker to a detected signal; you can hear the sig-nal audio.• When the sweeping stops, push [CLR] to cancel theBand Scope function.Center frequency (Example: 146.010 MHz)Example: The tuning step is set to 10 kHz, and astrong signal is received on 146.060 MHz.Example: Continuous sweep on 146.010 MHzWhile continuouslysweepingWhen the sweeping stops,rotate [DIAL] to move thesweep marker to a detect-ed signal; you can hearthe signal audio.
