Battery Life Indicator - Seiko S034 Instructions Manual

The electroluminescent display loses its luminance as the battery voltage decreases.
In addition, the luminance level of the electroluminescent panel decreases
gradually over time. After 500 hours of use, the level decreases by about half.
* 500 hours of use corresponds to 7 years of use if the illuminating light is used
140 times a day.
When the illuminating light becomes dim, have the battery replaced 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
stopwatch was purchased, or an AUTHORIZED SEIKO DEALER. It will be
replaced at cost.
While the illuminating light is used, the stopwatch may make a very small noise.
However, this is not a malfunction.

When all the digits start flashing, replace the battery with a new one as soon as possible.
Otherwise, the display will become blank and the watch will stop operating 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.
