English HOW TO USE THE TELEMETER Before beginning, check that the stopwatch has been reset. START (Flash of light) 1 Press button A to start the stopwatch as soon as you see the light. STOP (Crash of thunder) 2 When you hear the sound, press button A to stop the stopwatch. 3 Read the telemeter scale that the stopwatch second hand points to. Approx. 3 km * Please note that the stopwatch 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 only when the measured time is less than 60 seconds. 14 BATTERY CHANGE 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. For battery replacement, we recommend that you contact an AU­THORIZED SEIKO DEALER and request SEIKO SR936SW battery. * If the stopwatch is used for more than 1 hour a day, the battery life may be less than the specified period. * After the battery is replaced with a new one, set the time/calendar. l Battery life indicator When the battery nears its end, the small second hand moves at twosecond intervals instead of normal one-second intervals. In that case, have the battery replaced with a new one as soon as possible. * The watch remains accurate while the small second hand is moving at two-second intervals. 15 English
