4.3 Setting the Squelch
The Squelch circuit sets the threshold for cutting off
the receiver when the signal is too weak for reception
of anything but noise.
To properly set the squelch, rotate the SQ knob
counterclockwise until audio is heard.
Then rotate clockwise until background noise
disappears.
4.4 Setting the Power Output
The choice of power output is dependent upon the distance of transmission
and transmitting conditions.
Press and release the HL/USER key to toggle the TX power from LOW (1
watt to HIGH (5 watts). The corresponding LO or HI indicator appears on the
LCD.
Note: Some channels are limited by regulation to be low power only. If the
HILO operation request is denied, an error tone beeps.
