Vertex Standard VX-8R ユーザーズマニュアル

The Spectrum Analyzer allows viewing operating activity on channels above or below the
current operating channel in the VFO mode.

The display indicates the relative signal strength on channels immediately adjacent to the
current operating frequency.

Three basic operating modes for the Spectrum Analyzer are available:
1Time

when the Spectrum Analyzer is activated between 30 ~ 580 MHz (except
FM Broadcast Band).

channel steps with the amateur band you are using.

4. To turn the Spectrum Analyzer off and operate on the center (displayed) channel,

press the 

 key to stop the sweep, if needed, then press the
