➥ Rotate [RF] control clockwise to increase, counter-
clockwise to decrease the receiver sensitivity.
NOTE:
When [RF] control is adjusted CCW in FM mode,
audio output decreases then disappears. This is nor-

➥ When no signal is received, rotate [SQL] control
fully counterclockwise first, then rotate [SQL] clock-
wise to the point that the noise just disappears.
• Push and hold to open the squelch temporar-
ily.
