the following is on the display.
ERROR message (indicating sensor malfunction)
BATT message (indicating low battery power)
Make sure that the watch is set to the correct time of day.
Check the glass, case and band for cracks or chips.
Make sure that the band is fastened securely around your wrist.

GETTING ACQUAINTED
After Skin Diving/Snorkeling
To avoid corrosion, rinse your watch thoroughly with fresh water to remove
salt water, dirt, etc. (When possible, soak the watch in fresh water overnight to
make sure that all salt is removed.)
When using a metal band, occasionally clean inside the gaps in the band
using a soft toothbrush and soapy water. Failure to do so can result in
corrosion of the watch, soiling of clothing, or irritation to sensitive skin.
About This Manual
GENERAL GUIDE
Altimeter Mode
Note
The watch does not make any allowance for leap years. Be sure to make the
necessary changes to the date setting to allow for February 29 during a leap year.
This watch uses a pressure sensor to measure air pressure (barometric pressure).
There are two types of measurements: regular barometric pressure readings and
Barometer Mode barometric pressure readings , which are described below.
You can calibrate the pressure sensor if you suspect the barometric pressure
reading is incorrect.
Important!
The pressure sensor built into this watch measures changes in air pressure, which
you can then apply to your own weather predictions. It is not intended for use as a
precision instrument in official weather prediction or reporting applications.
Regular Barometric Pressure Readings
The watch takes regular barometric pressure readings every three hours starting from
midnight each day. The data produced by these readings is used for the graphic
display and barometric pressure graph in the Timekeeping Mode.
Measurements are taken nine, six, and three seconds before each of the regular
measurement times.
The watch calculates the average of the three readings, and displays the result.
Regular barometric pressure readings are different from the readings taken in the
Barometer Mode. Regular barometric pressure readings are used as the data for the
barometric pressure graph and graphic indicator on the Time and Pressure Graph
Screen in the Timekeeping Mode.
To display regular barometric pressure reading graphics
In the Timekeeping Mode, press D to display the Time and Pressure Graph Screen
for the regular barometric pressure readings.
The barometric pressure graph shows the relative changes between readings for the
past 18 hours. The flashing marker on the right indicates the latest reading.
Graphic indicator
Button operations are indicated using the letters shown
in the illustration.
Each section of this manual provides you with the
information you need to perform operations in each
mode. Further details and technical information can be
found in the "REFERENCE" section.
