GETTING ACQUAINTED |
|
Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to carefully read this manual and keep it on hand for later reference when necessary.
Precautions
•This watch is intended for use up to skin diving and snorkeling. It is not designed for use during scuba diving.
•Never operate the buttons of the watch while underwater or while floating on the water’s surface.
Before Skin Diving/Snorkeling
•Before beginning skin diving or snorkeling, check to make sure that neither of 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.
While Skin Diving/Snorkeling
•The indicator ERROR on the display may indicate bad data.
•To avoid scratching the watch, take care when skin diving/snorkeling near rocks or coral.
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.

To reset the seconds count to zero
1.While the Time and Date screen is on the display in the Timekeeping Mode, hold down Auntil the second’s digits start to flash, which indicates the setting screen.
2.Press Dto reset the seconds count to 00.
•Pressing D while the seconds count is in the range of 30 to 59 resets the seconds to 00 and adds 1 to the minutes. In the range of 00 to 29, the minutes count is unchanged.
3.Press Ato exit the setting screen.

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.
BAROMETER
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.
