b) If left idle for 30 seconds in these functions, the watch will resume
back to the altitude-sea level pressure display.
c) After changing the battery "--" will be shown as no data kept in
the sea level pressure history memory and bar graph will be clear

HOW TO SET THE SEA LEVEL PRESSURE

When you first use the RA201, please calibrate the sea level
pressure. Once the sea level pressure is calibrated, the altitude will
automatically calibrate to the reference altitude using the built-in
auto-calibration function.
1. Press and hold SET for two seconds in altitude-sea level pressure
display to enter the sea level pressure mode.
2. Press +/- to increase or decrease the values.
3. Press SET to confirm the setting and then quit the setting mode.
Refer to Fig. 4f to set the sea level pressure.
Notes:
a) The current sea level pressure can be obtained from most of the
newspapers, local news and radio weather reports or through the
internet weather station.
b) It is necessary to re-calibrate the sea level pressure and altitude
again once the product is placed in a pressurized cabinet such as
an airplane.
