4.3.1 Setting the Sea Level Pressure
Setting the sea level pressure can be used in setting the altitude measurement on the Wristop Computer if the
altitude is not known.
To set the sea level pressure:
1. PRESS the [Select] button and hold in for 2 seconds. Located in Field 2, the current sea level pressure will
begin to flash.
2. PRESS the [+] button to scroll the pressure upward or
PRESS the [-] button to scroll the pressure downward.
3. At the desired pressure, PRESS the [Mode] button to accept the changes and return to the main mode.
Once the user completes this process, the altitude measurement on the Wristop Computer is correct within a
range of some ten meters or few hundred feet.
Note: Information on the current sea level pressure can be obtained through newspapers, local news and radio
weather reports, the local airport facility or through the Internet under local weather.
If the user does not press any button for 1 minute in the setup mode, the display will automatically exit setup.
