HOW TO USE THE ROTATING BEZEL
The altitude scale graduated on the rotating bezel can provide an approximate altitude on
the basis of the atmospheric pressure measured.
The altitude scale can be adjusted to the atmospherie condition to provide accurate altitude
measurement.
How to read the altitude scale
(1) Turn the rotating bezel to set “0” on the altitude scale to "1013hPa" on the barometer
scale.
(2) Read the altitude scale where the barometer hand “1” points to.
How to adjust the altitude scale
Atmospheric pressure of your location varies depending on the weather condition. To
obtain accurate altitude measurement, therefore, turn the rotating bezel to adjust the
altitude scale.

1 Chose a location whose altitude (height above the sea) is known to you, and turn the
rotating bezel to set the graduation of the altitude scale corresponding to the known
altitude to the barometer hand "1".
Ex.) When you are at an altitude of 500m and the barometer hand "1" points to "950
