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, calendar and alarm before using the watch.
*Please note that if the IC is reset, all the stored data will be deleted.
HOW TO RESET THE BUILT-IN IC
The miniature battery which powers your stopwatch should last approximately 3 years (or approximately 7 years if the automatic shutt-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.
●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, the alarm sounds more than once a day, the
built-in LED light is turned on more than 3 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.
●The LED (Light Emitting Diode), which is used as a source of the built-in light, decreases its brightness as the battery life is coming to an end and the electric voltage
becomes low.
●Battery life indicator

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

AUTOMATIC SHUT-OFF FUNCTION
When the automatic shut-off function is set to “ON” in the TIME/CALENDAR SETTING display, the following energy-saving functionswill be activated to help
extend the battery life.
●Regardless of the display modes, when the stopwatch is left untouched for one hour, the display becomes blank in order to minimize battery consumption.
●The current time will be displayed once every 10 seconds even while the display is blank, to indicate that the blank display isnot caused by battery exhaustion.
●While the stopwatch or timer is measuring, the display will not become blank for the energy-saving functions.
●If the alarm is engaged, the alarm will sound at the designated time even while the display is blank.
●To return to the normal display, press either Button A, B, C or D. The last display before it became blank will be shown.
Automatic shut-off mark
When the automatic shut-off function
is set to “ON,” this mark appears in any

stopwatch is in the setting mode.
HOW TO STOP THE ALARM MANUALLY WHILE SOUNDING
●The alarm sounds for approximately 20 seconds at the designated time and automatically stops.
●Press any of buttons A, B, C, or D to stop the alarm while sounding.
