Illumination
This watch has an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark.
•
The electro-luminescent panel that provides illumination
loses power after very long use.
•
Illumination may be hard to see when viewed under
direct sunlight.
•
The watch may emit an audible sound whenever the
display is illuminated. This is due to vibration of the EL
panel used for illumination, and does not indicate
malfunction.
•
Illumination turns off automatically whenever an alarm
sounds.
•
Frequent use of illumination runs down the battery.
