BATTERY CHANGE The miniature battery which powers your watch should last approximately 5 5 years. However, because the battery is inserted at the factory to check Years| 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. For battery replacement, we recommend that you contact an AUTHORIZED SEIKO DEALER and request SEIKO SR927$W battery. + Ifthe stopwatch is used for more than 2 hours à day, the battery life may be less than the specified period.

• After the battery is replaced with à new one, set the time/calendar and adjust the Stopwatch hand position. © Battery life indicator When the battery nears its end, the small second hand moves at two-second intervals instead of normal one-second intervals. In that case, have the battery replaced with à new one as soon as possible. + The watch remains accurate while the small second hand is moving at two-second intervals.

À waRNING © Do not remove the battery from the watch. necessary to take out the battery, keep it out of the reach of children. If it, heat or otherwise tamper with the battery, and never expose it to fire. The battery may burst, become very hot or catch fire. © Thebatteryis not rechargeable. Never attempt to recharge it, as this may cause battery leakage or damage to the battery. usiuz

English TELEMETER (for models with telemeter scale on the dial) © The telemeter can provide a rough indication of the distance to the source of light and sound. © The telemeter indicates the distance from your location to an object that emits both light and sound. For example, it can indicate the distance to the place where htning struck by measuring the time elapsed after you see a flash of lightning until you hear the sound. © Aflash of lightning reaches you almost immediately while the sound travels to you at a speed of 0.33 km/second. The distance to the source of the light and sound can be calculated on the basis of this difference. © The telemeter scale is so graduated that the sound travels at a speed of 1 km in 3 seconds.* “Under the condition of temperature of 20° CIG8°F) À CAUTION The telemeter provides only a rough indication of the distance to the place where lightning struck, and therefore, the indication cannot be used as the guideline to avoid the danger of lightning. It should also be noted that the speed of the sound differs depending on the temperature of the atmosphere where it travels.

HOW TO USE THE TELEMETER

Before beginning, check that the stopwatch has been reset. START (Flash of light) Press button À to start the stopwatch as soon as you see the light STOP When you hear the sound, press button À to stop the Stopwatch. (Crash of thunder) Read the telemeter scale that the stopwatch second hand points to. Approx. 3 km Please note that the stapwatch second hand moves in 1/5 second increments and does not always point exactly to the graduations of the telemeter scale. The telemeter scale can be used oniy when the measured time is less than 60 seconds. ys1fBua
