would still be running in the background. Press HIDDEN again to show the

(7) If necessary, parameters such as FREQ GAP, LEV GAP and Threshold,
etc, can be set in SEARCH SET menu. Tips are, set FREQ GAP to half of
channel gap like 12.5KHz, set LEV GAP to 5dB or above, set Threshold to -
30dBm. (With a whip antenna of one fourth wavelength, that is equivalent to a
1W walkie-talkie within 50 meters). Frequency gap should be set to less than a
half of the channel gap, like 10kHz, while amplitude gap should be set to 10dB
or bigger.
Utilise the occupancy filter function properly. To rule out constant
emission strong signals, set the upper limit to 90%, and the lower limit to 0%.
After that, observe the colorful indicator, the top should be empty and the rest
part should be colorful.
