Raymarine L470 Setup Instructions, For example, if the temperature reading on, Shallow Alarm

	unit says that you are moving faster than you really are, you
	can adjust the Speed Cal figure to a smaller number. If the
	unit says that you are moving slower than your actual
	speed, use a larger number for Speed Cal. The setting can
	range between 75 and 125. Use the < and > controls to
	change the value. For more information, see the section on
	“Calibrating the Sensors.”
Temp Cal	This unit can display the water temperature. You may want
	to fine-tune the signal from the transducer to get an
	accurate display. The displayed number indicates an offset
	added to the measured temperature. (This offset will be
	measured in °F or °C, depending on the setting used for
	Temp Units.)	For example, if the temperature reading on
	the FishFinder Page tends to read 2°F too high, you can
	correct for this by setting Temp Cal to -2.0°. The setting
	can range between -9.9° and +9.9°. Use the < and >
	controls to change the value.
Depth Digits	This item sets the size of the digits used to show the bottom
	depth on all of the display pages except for the Window and
	Digital Pages. The “STD.” (standard) setting will display
	digits which are 7 mm tall, and the “LARGE” setting will
	display digits which are 15 mm tall. Use the < and >
	controls to change the setting.
Shallow Alarm
	You can set an alarm to trigger whenever the boat moves
	into water which is shallower than a limit you set. Use the
	< and V controls to move to the line for Shallow Alarm
	and use the > control on the Page Control Pad to turn this
	item on. Once you do this, the display will ask which depth
	you want to use as a limit. Use the < and > controls to set
	the limit you want. When the shallow alarm is set, the letter
	“S” will appear in the upper left-hand corner of the normal
	displays. If you move into shallow water and trigger the
	alarm, the letter “S” will begin to flash, and the buzzer will
	sound. Press the			button to silence the buzzer. The
			CLEAR
	letter “S” will continue to flash until you move into
	deeper water.
