MAIN FUNCTIONS
• Display showing the channel in use;
• RF GAIN: adjusts the rx sensitivity. By turning the knob clockwise the rx sen-
sitivity will increase; by turning counter-clockwise it will be reduced (this is very
helpful in case of strong signals received);
• SQUELCH: the squelch eliminates the background noise in rx. To get the best
sensitivity in rx the squelch should be adjusted exactly at the level when the
background noise disappears;
• CH/EMG: this knob allows to switch immediately to the emergency channel.
The emergency channel can be set by the user.
