5. Other features
Automatic squelch
Your PMR is fitted with automatic squelch circuitry which filters
out weak transmissions and unwanted extraneous noise.
These signals may be picked up as background static and are
usually caused by the nature of the terrain or the fact that your
radio is at the limit of its range.
Monitor
With this function, you can switch off the automatic squelch
feature, temporarily or permanently. In this way, the maximum
possible range of your radio can be used, but it may pick up
static signals as well. You can adjust the speaker volume by
the noise of the static.
x Press MENU and UP button simultaneously. The monitor
signals will appear in the LC display.
x Press MENU the button to restore the automatic squelch
function.
