All possible keys and their functions are listed. Note that some of the keys are not
available depending on your Navman VHF radio model.
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 1/4
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.
