ILLUMINATING LIGHT
While the light button is kept depressed in the time/calendar,
stopwatch, timer or alarm display, the illuminating light evenly
illuminates the display for easy viewing in the dark.
TIME
Notes:
1. The watches with illuminating light work with one battery.
When the illuminating light begins to lose its luminance,
this is an indication that the battery is depleted. We recommend
that you change the battery before the watch itself stops.
2. If the illuminating light is used continuously for a long time,
the battery life may be less than the specified period.
