English BATTERY CHANGE 3 Years 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. When the battery expires, be sure to replace it as soon as possible to prevent any malfunction. It will be replaced at cost. For battery replacement, we recommend that you contact an AUTHORIZED SEIKO DEALER and request SEIKO CR2032 battery. * The battery life may be less than 3 years if the regular alarm is used more than 10 seconds a day, the illuminating light more than 10 seconds a day, and/or the diving function more than 50 times a year, one hour per dive. Notes: 1. The log data stored in the dive log function is not erased when the battery is replaced with a new one. It is possible, however, for the stored log data to be inadvertently erased during the function checking procedures after battery replacement. It is recommended that the log data in memory be noted down in your log book before requesting a battery change. 2. For battery replacement, take the watch to the retailer from whom it was purchased. The work of replacing the battery is conducted at a SEIKO SERVICE CENTER. For safety's sake, the watch will also undergo a strict check on its water resistant quality and depth measurement function in addition to battery replacement. Therefore, it will take approximately 2 weeks before the watch is returned to you. 3. After the battery is replaced with a new one, "meters (m) and centigrade (° C)" are automatically set for the measurement units. Before diving, therefore, set the measurement units as required. (See "SELECTION OF MEASUREMENT UNITS") Battery life indicator If the battery mark is shown on the display, the watch will stop operating in about a week. Take the watch to the retailer from whom it was purchased to replace the battery with a new one. Battery mark • While the mark is shown, the watch cannot be used for diving. * While the battery mark is shown, the dive function will not start. If the battery mark starts flashing, the battery is nearing its end. Take the watch to the retailer from whom it was purchased immediately for battery replacement. 26 WARNING ● Do not remove the battery from the watch. ● If it is necessary to take out the battery, keep it out of the reach of children. If a child swallows it, consult a doctor immediately. CAUTION ● Never short-circuit, heat or otherwise tamper with the battery, and never expose it to fire. The battery may burst, become very hot or catch fire. ● The battery is not rechargeable. Never attempt to recharge it, as this may cause battery leakage or damage to the battery. English TO PRESERVE THE QUALITY OF YOUR WATCH ■ TEMPERATURES +60°C -10°C Your watch works with stable accuracy within a temperature range of 5°C and 35°C (41°F and 95°F). Temperatures over 60° C (140° F) or below -10° C (+14° F) may cause a slight time loss or gain or battery leakage or shorten the battery life. However, the above conditions will be corrected when the watch returns to normal temperature. ■ SHOCKS & VIBRATION Be careful not to drop your watch or hit it against hard surfaces. ■ PERIODIC CHECK 2 - 3 Years It is recommended that the watch be checked once every 2 to 3 years. Have your watch checked by an AUTHORIZED SEIKO DEALER or SERVICE CENTER to ensure that the case, buttons, gasket and crystal seal remain intact. ■ PRECAUTION REGARDING CASE BACK PROTECTIVE FILM If your watch has a protective film and/or a sticker on the case back, be sure to peel them off before using your watch. ■ MAGNETISM Your watch will not be affected by magnetism. NS ■ CHEMICALS Be careful not to expose the watch to solvents, mercury, cosmetic spray, detergents, adhesives or paints. Otherwise, the case, bracelet, etc. may become discolored, deteriorated or damaged. ■ CARE OF CASE AND BRACELET To prevent possible rusting of the case and bracelet, wipe them periodically with a soft dry cloth. ■ STATIC ELECTRICITY The IC (Integrated Circuit) used in your watch will be affected by static electricity, which may disturb the display. Keep the watch away from close contact with objects such as TV screens, which emit strong static electricity. ■ LIQUID CRYSTAL PANEL 7 Years The normal life expectancy for a liquid crystal panel is approximately 7 years. After that it may decrease in contrast, becoming difficult to read. Please contact your AUTHORIZED SEIKO DEALER or SERVICE CENTER if you wish to have a new panel fitted (guaranteed one year). 27
