ILLUMINATING LIGHT (Electroluminescent panel)
● The electroluminescent panel loses its luminance as the battery voltage gets lowered.
Also, its luminance level decreases gradually with use. After 120 hours of use, the level
decreases by about half.
● When the illuminating light becomes dim, replace the battery with a new one. If the 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. 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.

● The battery life may be less than 2 years if the alarm is used for more than 10 seconds
a day and/or the illuminating light more than once a day.
● As 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.
