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.

Warning!
•••••
Always make sure you are in a safe place whenever you are reading the
display of the watch using the auto light switch. Be especially careful when
running or engaged in any other activity that can result in accident or injury.
Also take care that sudden illumination by the auto light switch does not
startle or distract others around you.
•••••
When you are wearing the watch, make sure that its auto light switch is
turned off before riding a bicycle or operating a motorcycle or any other
motor vehicle. Sudden and unintended operation of the auto light switch can
create a distraction, which can result in a traffic accident and serious
personal injury.
To turn the auto light switch on and off
In the Timekeeping Mode, hold down
B
for about three seconds to toggle the auto
light switch on (auto light switch on indicator displayed) and off (auto light switch on
indicator not displayed).
•
The auto light switch on indicator is on the display in all modes while the auto light
switch is turned on.
