The Band Scope allows viewing operating activity on channels above or below the current

The display indicates the relative signal strength on channels immediately adjacent to the
current operating frequency.
Two basic operating modes for the Band Scope are available:
1time : In this mode, the radio sweeps the current band once.
CONTINUOUS
: In this mode, the radio sweeps the current band repeatedly until the SCAN
switch is pressed, or the Band Scop is turned off.
