Notes
• Normally, displayed altitude values are based on the watch's preset
conversion values. You also can specify a reference altitude, if you want.
See "Specifying a Reference Altitude" (page E-76).
• Altitude is displayed in units of 5 meters.
• The measurement range for altitude is –700 to 10,000 meters.
• The measured altitude may be a negative value in cases where there is a
reference altitude value set or because of certain atmospheric conditions.
• The displayed altitude value changes to
altitude falls outside the measurement range. The altitude value will be
displayed again as soon as the measured altitude is within the allowable
range.
