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
In Barometric Mode, by detecting changes in air pressure,
this unit makes weather predictions. Illustrated weather
forecasts symbols indicate forecasts as sunny, slightly
cloudy, cloudy, and rainy.

FORECAST
Displayed forecast symbols are intended indicate weather
forecasts for the coming 12 to 24 hours. The radius of the
forecast is approximately 30 to 50 km.
A small icon indicates that the unit is in Barometric
Mode and that the displays are barometer related.
NOTE
1. The accuracy of weather forecasts, when only using
atmospheric pressure trends, are approximately 70
to 75 percent.
2. The weather forecasts from this unit are predictions
that cover the next 12 to 24 hours. It may not
necessarily reflect the current situation.
3. The "Sunny" icon, as applies to nighttime, implies
clear weather.
