Illumination
This watch has an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark.
Illumination Precautions
• The electro-luminescent panel that provides illumination
loses power after very long use.
• Illumination may be hard to see when viewed under
direct sunlightg.
• 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 automatically turns off whenever an alarm
sounds.
• Frequent use of illumination runs down the battery.

seconds start to flash, which indicates the setting
screen.

screen is on the display.
