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 LED 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
-While a signal receive operation is in progress
