ILLUMINATING LIGHT (Electroluminescent panel)
The electroluminescent panel loses its luminance as the battery voltage decreases. Also, its
luminance level decreases gradually with use.
When the illuminating light becomes dim, replace the battery with a new one. If the illuminating light
remains dim after the battery is replaced, have the electroluminescent panel replaced with a new one
by the retailer from whom the watch was purchased, or an AUTHORIZED SEIKO DEALER. It will be
replaced at cost.
While the illuminating light is used, the watch gives out a slight noise. However, this is not a
malfunction.
BATTERY CHANGE
The miniature battery which powers your watch should last approximately
2 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 CR2025 battery.
2
Years
* The battery life may be less than 2 years if the alarm is used for more than 20 seconds
a day and/or the illuminating light more than 3 times a day.
Battery life indicator
When all the digits start flashing, have the battery replaced with a new one as soon
as possible.
