Casio 3145 Watch User Manual


 
E-80
When you are wearing the watch, make sure that its auto light switch
is turned off before riding on 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 L for about three seconds to toggle the
auto light switch on (A.EL displayed) and off (A.EL not displayed).
The auto light switch on indicator (A.EL) is on the display in all modes while
the auto light switch is turned on.
The auto light switch turns off automatically whenever battery power drops
to Level 3 (page E-88).
Illumination may not turn on right away if you raise the watch to your face
while a barometric pressure or altitude measurement operation is in
progress.
