Using Auto Light
When Auto Light is enabled, angling the watch towards your face at an angle of 40˚
or greater will illuminate the display automatically.
Note
Auto Light is disabled automatically while an alarm is sounding.
◆ Auto Light Precautions
The Auto Light may not operate properly when the watch is angled towards your
face from an angle greater than about 15 degrees as shown in the illustration
below.
Leaving Auto Light enabled can run down the watch's battery
due to frequent display illumination.
Electro-static charge or magnetism can interfere with proper Auto
Light operation. If this happens, try lowering your arm and then
angle it towards your face again.
When moving the watch you may note a slight rattling sound.
This is due to operation of Auto Light, which determines the
current orientation of the watch. It does not indicate malfunction.
Auto Light will remain enabled for about 6 hours after you turn it
on. After that Auto Light will disable automatically.
●
Press D to toggle the illumination duration setting between [LT1]
