HOW to Reset the BUILT-IN IC, Battery Change

HOW TO RESET THE BUILT-IN IC

When an abnormal display (broken digits, etc.) appears, follow the procedure below. The built-in IC will be reset and the watch will resume normal operation.

HOW TO RESET THE IC

Be sure to press buttons A, B, C, and D at the same time for 2 to 3 seconds. The display will become blank, and then “Sun ’06 1-1 A12:00" will be displayed. Set the time and calendar before using the watch.

*Please note that if the IC is reset, all the stored data will be deleted.

BATTERY CHANGE

The miniature battery which powers your stopwatch should last approximately 3 years (or approximately 7 years if the automatic shut-off function is activated). However, because the battery is inserted at the factory to check the function and performance of the stopwatch, 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 a SEIKO CR2032 battery.

●For Cal. S056, if the stopwatch is used for more than 3 hours a day, the confirmation sound for button operation rings more than 50 times a day, the battery life may be less than the specified period.

●For Cal. S057, if the stopwatch is used for more than 3 hours a day, the Double Repeat Timer function is used more than 5 times a day, and the confirmation sound for button operation rings more than 50 times a day, the battery life may be less than the specified period.

●Battery life indicator

When all the segments of the display start flashing in the TIME/CALENDAR display, or when “ ” mark starts flashing in other displays, the stopwatch may run down in 2 to 3 days. We suggest that you have the battery replaced by a SEIKO DEALER.

*Even though the display is flashing, time accuracy is not affected.
