Turning on Illumination with Auto Light
40 degrees
minimum
With the watch on your
wrist, position it parallel
with the ground.
Rotate your arm so the watch
is angled at about 40 degrees,
so you can read its face.
• You should be wearing the watch on the outside of your
wrist when using auto light.
• Make sure that a line running from the left side (9 o’clock) to
the right side (3 o’clock) of the watch is within ±15 degrees
parallel with the ground. Auto light may not operate properly
if the angle is greater than 15 degrees.
Important!
• Illumination may be difficult to see under bright sunlight.
• Illumination turns off automatically if an alarm sounds, etc.
• You may notice a slight sound from the watch while illumination is turned on. This is the
sound of EL panel vibration and does not indicate malfunction.
Auto Light Precautions
• To conserve battery power, the auto light switch can remain on for a maximum of about six
hours. After that, it will turn off automatically, and the “ ” indicator will disappear from the
display.
• If you want to continue using auto light, hold down the D button for about two seconds
again until the “ ” indicator reappears. Note, however, that frequent use of auto light
can run down the battery.
• Illumination may not turn on immediately when you angle the watch towards your face. This
does not indicate malfunction.
• Illumination remains turned on for about 1.5 seconds only, even if you leave the watch
angled towards your face.
• Illumination may turn on unintentionally when you wear the watch on the inside of your wrist,
when you shake your arm, or when you raise your arm. Be sure to turn off the auto light
switch whenever you do not need illumination.
• Keep the auto light switch turned off whenever you are wearing the watch on the inside of
your wrist.
• Electro-static charge and magnetism can interfere with auto light operation and even make
operation impossible. If this happens, lower your arm to the starting position and then raise it
again. If you still have trouble with auto light illumination, try lowering your arm down to your
side and then raise it to your face for reading.
• You may hear a faint rattling sound when you move the watch around. This sound is caused
by the movement of a metal bulb that controls operation of the auto light switch, and does
not indicate malfunction.
