Illumination Precautions
The electro-luminescent panel that provides illumination loses power after very longx
use.
Illumination may be hard to see when viewed under direct sunlight.x
The watch may emit an audible sound whenever the display is illuminated. Thisx
is due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
Illumination automatically turns off whenever an alarm sounds.x
Frequent use of illumination runs down the battery.x
