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 turn on the backlight under bright light.
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.
