For best results, please read the instructions in this booklet carefully before using your SEIKO Analogue Quartz Watch. Please keep this manual handy for ready reference. [. . . ] Before diving, therefore, it is recommended that you make a note of the stored data in your log book, etc. WHILE DIVING Use the watch only within the operational temperature range for depth measurement (0° C ~ 40° C or 32° F ~ 104° F). Take care not to hit the watch against hard objects such as rocks. While you are underwater, never unscrew the crown or pull it out. Check that the DEPTH hand moves properly. While you are at a depth of 1. 6 m or more underwater, the alarm will not ring so that it is not confused with the beeping sound for the rapid ascent warning. The depth measurement is made every second except while the DEPTH hand is moving. While the watch is giving the rapid ascent warning, it will not measure the depth. In some cases, however, the watch stops the warning momentarily to indicate the depth and then resumes the warning. Depending on the aquatic environment where the watch is used, the beeping sound for the 21 rapid ascent warning may or may not reach your ears. If you find the DEPTH hand indicating the 58-minute position while you are underwater, you should either ascend to the surface immediately or, if you choose to remain underwater, not depend on diving information provided by the watch. The watch measures the depth of water on the basis of seawater having a specific gravity of 1. 025. When it is used in fresh water such as lakes, therefore, the displayed depth should be corrected by multiplying it by 1. 025. Ex. Assuming that the gravity of the lake where you are diving is 1. 00 If the watch indicates 29. 2 m, the actual depth is: 29. 2 m x 1. 025/1. 00 = 30. 0 m English While you are underwater, none of the buttons will work for safety's sake. AFTER DIVING After making a dive, be sure to rinse the watch in fresh water, and wash out all seawater, soil, sand, etc. If dust forms between the case and rotating bezel, the pressure sensor will not function properly. sticking to the water contact sensor unit, as this will cause a malfunction.
