ALTI Current Altitude
1. The current altitude is always displayed on the upper display.
2. To get accurate basis altitude, the cyclist should calibrate the
altitude before each ride.
3. The measurement is based on the principle that atmospheric
pressure decreases as elevation increases.
4. The altitude is measured by means of the atmospheric pressure,
so it's weather-dependent.
5. You may obtain the altitude data from a topographic map or the
Internet.
6. The altitude of the altimeter is pre-calibrated by the precise
instrument at the factory before shipment.
Current Speed
1. The current speed is always shown on the middle display during
riding.
2. The speed data are updated per second.
3. For Bike 1, when you do not ride the bike for more than 4
seconds, the speed data will be reset to zero.
