1-6 Basic Operation and Key Functions

All possible keys and their functions are listed here. Note that some of the keys may not be available depending on your Lowrance 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.
16/9	Priority Channel. Also on the microphone. Press to cancel all other
	modes and to tune into the priority channel. Press again to return to your
	original channel.
	The default is Channel 16. To make Channel 09 the priority channel, hold
	down 16/9 until a beep sounds and 09 is displayed.

16Priority Channel. LVR-250 EU only. Also on the microphone. Press to cancel all other modes and to tune into the priority channel. Channel 16, on high power. Press again to return to your original channel.
