NOTES ON THE ALTIMETER FUNCTIONS
Altitude readings may be affected by air pressure change.
Sudden changes in pressure, temperature and weather
may cause an inaccurate altitude reading.
The unit cannot distinguish between change of air
pressure caused by a weather change or by an altitude
change. However, accurate functioning of the unit can
be maintained by following a few simple steps.
To ensure that accurate altitude readings are
maintained:
- At the start of a journey, switch the unit to the
Altimeter Display Mode. The last barometric pressure
will remain stored until the unit is switched back to the
Barometer Display Mode.
-When a journey is completed, or if the unit is
maintained at the same altitude for extended periods,
it is recommended to switch to the Barometer Display
Mode.
- If a journey is particularly long or extended over a
long distance of varying altitudes, occasionally
compare the unit’s displayed altitude against known
actual altitudes. If necessary, manually calibrate the
altitude to maintain correct altitude readings.
GENERAL OPERATION OF THE
BAROMETER AND WEATHER FORECAST
FUNCTIONS
