for it to operate.
• See “Illumination Precautions” for other
important information about using illumination.
To turn on illumination manually
Press L in any mode to illuminate the display for about one second.

About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on, whenever you
position your wrist as described below in any mode.
Note that this watch features a “Full Auto EL Light”, so the auto light switch
operates only when available light is below a certain level. It does not
illuminate the display under bright light.
• The auto light switch is always disabled, regardless of its on/off setting,
when any one of the following conditions exists.
While an alarm is sounding
During sensor measurement
While a bearing sensor calibration operation is being performed in the
Digital Compass Mode
During tide data calculation
Moving the watch to a position that is parallel to the ground and then tilting
it towards you more than 40 degrees causes illumination to turn on.
• Wear the watch on the outside of your wrist.
