WATER RESISTANCE Your timekeeper is water resistant and is manufactured to withstand up to 3 atmospheres of pressure/bar (water pressure at a 30-meter or 100-foot depth). It can be used at an athletic meet or when playing sports where there may be accidental contact with water, such as rain or splashes. 2. SHOCKS Be careful not to drop your timekeeper or hit it against any hard surfaces. 3. MAGNETISM Your timekeeper will not be affected by magnetism. 4. TEMPERATURES Your timekeeper is preadjusted to function with stable accuracy when used at a normal temperature range 15°C - 35°C). • Extremely high temperatures Keep your timekeeper away from direct sunlight or a hot place. * If it is used or left in such a place, the digital display may become black. But this condition will disappear without any aftereffect when the temperature returns to normal. • Extremely low temperatures Do not use or leave your timekeeper in a cold place. If it is used or left in such a place for a long time: 11 A small amount of time loss/gain may occur. 2) The change of the digits may become slow. (The timekeeper remains accurate.) The normal performance of your timekeeper, however, will return when the temperature returns to normal. • If it is exposed to a temperature below -10°C or over +60°C for a long time, this may cause the timekeeper to stop, the battery electrolyte to leak, or the battery life to be shortened. ■LIQUID CRYSTAL PANEL When the liquid crystal panel of your timekeeper is used for more than 7 years, its contrast may decrease and it may become difficult to read digits on the panel. ■TO PRESERVE THE QUALITY OF YOUR WATCH PERIODIC CHECK It is recommended that your timekeeper be checked at the time of the battery replacement or once every 2 to 3 years for oil condition, battery electrolyte leakage, entrance of moisture or perspiration, etc, by the retailer from whom your timekeeper was purchased. An adjustment or repair may be required, depending on the result of the check. * Take this opportunity to have the gasket replaced with a new one. * When replacing parts, be sure to specify the "SEIKO parts". ■BATTERY CHANGE BATTERY LIFE A new normal battery will last approximately 2 years. * If the timekeeper is used for more than 2 hours a day and the alarm more than 5 times a day I more than 25 seconds with the announcing sound included), the battery life will be less than 2 years. The battery will last approximately 3,000 hours in continuous use as the 30-minute timer. ▪ The battery in your timekeeper may run down in less than 2 years after the date of purchase, as it is a monitor battery which is inserted at the factory to check the function and performance of the timekeeper. * The price of the monitor battery is not included in that of the timekeeper. It will therefore be replaced with a new one only at cost even if it runs down within the guarantee period. BATTERY REPLACEMENT When replacing the battery, be sure to take your timekeeper to the retailer from whom it was purchased or an AUTHORIZED SEIKO DEALER, and specify the "SEIKO SB battery". If an old battery is kept in the timekeeper for a long time, a battery electrolyte leakage may occur and cause a malfunction of your timekeeper. When the battery has run down, replace it as soon as possible to prevent any possible malfunction. " When the battery is taken out of the timekeeper, keep it out of the reach of children. If children happen to swallow it, consult a doctor immediately.
