Should your instrument not be showing the page containing the fuel level when this alarm first
activates, the relevant page will be shown automatically.

Items in the calibration menu
ALT cal
This is a technical function that is used to calibrate your altimeter to an exact reference. On the
back of your altimeter you will find the calibration number that has been determined to result in
the most accurate reading of your altimeter. This is the value that should be entered here. Should
you have access to an accurate reference you may use this function to calibrate your altimeter.
Before you do this, ensure that you have your local pressure set to coincide with a calibrated and
certified reference.
Your altimeter has been calibrated by the factory to an accuracy of +/- one mB or approximately
+/- 30 ft (10m).
ASI Cal
This function is used to calibrate your airspeed indicator. During the factory calibration a factor
has been determined and entered here that will give you accurate airspeed provided your pitot
tube is not influenced by pressure effects caused by airflow around your airframe.
The calibration works in % of the reading and you can increase or decrease the reading if
required to help cancel out under or over reading of the airspeed indicator on your aircraft.
The original calibration factor has been written onto the back of your instrument.
