All possible keys and their functions are listed. Note that some of the keys are not available depending on your Northstar 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.

	modes and to tune into the priority channel. Press again to return to your original

	The default is Channel 16. To make Channel 09 the priority channel, hold down 16/9
	until a beep sounds and 09 is displayed.
16	Priority Channel. VHF 710EU. 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.
WX	Weather Channel. VHF 710US. In USA and Canadian waters, press to hear the most
	recently selected weather station. The WX symbol is displayed on the LCD.
	Press + or - to change to a diﬀerent weather channel. Press WX again to return to
	the most recent channel.
	If the weather alert mode (ALT) is ON and an alert tone of 1050Hz is broadcast from
