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 sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• 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.
• Frequent use of illumination runs down the battery.
Auto light switch precautions
• The auto light switch is turned off automatically whenever battery power is
at Level 4 (page E-110).
• Wearing the watch on the inside of your wrist, movement of your arm, or
vibration of your arm can cause frequent activation of the auto light switch
and illumination of the display. To avoid running down the battery, turn off
the auto light switch whenever engaging in activities that might cause
frequent illumination of the display.
• Note that wearing the watch under your sleeve while the auto light switch is
turned on can cause frequent illumination of the display and can run down
the battery.
