English 23 USE OF TERMS IN THIS MANUAL DEFINITION OF THE TERMS AND BASIC DESIGN OF THE WATCH The watch measures the depth of water from 1.5 m (5 ft) up to 99.9 m (328 ft) in 0.1 m (1 ft) increments. The measurement is made on the basis of seawater having a specific gravity of 1.
24 English EXPLANATION OF THE TERMS Explanation Terms No-de- compression limit (NDL) The maximum time during which the diver can stay at the current depth or in the selected depth rank without decompression procedure. The watch indicates NDL up to 200 minutes.
English 25 EXPLANATION OF THE TERMS Terms Explanation Terms Explanation The watch measures the water temperature every minute in 0.1 ° C (1 ° F) increments from -5.0 ° C up to +40.0 ° C (23 ° F up to 104 ° F). If the measurement is outside the range, “Lo” or “Hi” is displayed.
26 English BATTERY CHANGE 3 Y ears The miniature battery which powers your watch should last approximately 3 years . However, because the battery is inserted at the factory to check the function and performance of the watch, its actual life once in your possession may be less than the specified period.

Temperatures over 60 ° C (140 ° F) or below –10 ° C( + 1 4 ° F) may cause a slight time loss or gain or battery leakage or shorten the battery life.
28 English TROUBLESHOOTING Problem Possible cause Solution The watch gains/loses occasionally. The accuracy will be corrected when the watch returns to normal temperature.
English 29 Problem Possible cause Solution The watch calculates decompression diving even after a dive. The diver ascended defying the decompression stop violation warning. When the surface interval time is less than 5 minutes, making a decompression stop as indicated by the watch will return the display for no-decompression diving.
