1.6 Basic Operation and Key Functions
All possible keys and their functions are listed. Note that some of the keys are not available,
depending on your radio model and type of microphone.
Key Function
VOL/PWR Volume and Power. Turn clockwise to power on. Continue to turn
until a comfortable volume is reached. VOL/PWR will also adjust
the settings of an external speaker, if connected.
SQL Squelch or Threshold Level. Sets the threshold level for the
minimum receiver signal. Turn fully counterclockwise until random
noise is heard, then turn slowly clockwise until the random noise
disappears. Make another ¼ turn clockwise for best reception in
open sea conditions.
In areas of high noise (eg close to large cities) reception may
improve if sensitivity is reduced. Either turn SQL slowly clockwise
or use the LOCAL setting. See section 2.3.
