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 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 and 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 2.4.
