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.

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.

LCD

DISPLAYS

ON THE

UNIT

FORECAST SUNNY SLIGHTLY CLOUDY CLOUDY RAINY

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.
