Positioning Your Arm Correctly
•
You should be wearing the watch on the outside of your wrist
when using the full auto light switch.
•
Make sure that the left (9 o’clock)
and right (3 o’clock) sides of the
watch are within
±
15 degrees of
being parallel with the ground.
The full auto light switch 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 you press any button
causing a confirmation tone to sound or if an alert operation
is performed.
•
Illumination will not turn on while manual receive is in
progress.
•
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.
Full Auto Light Precautions
•
Frequent use of the full auto light switch can run down the battery.
•
The full auto light switch is disabled while you are viewing tide
data.
•
The full auto light switch may turn on illumination when the face of
the watch is shaded by your sleeve.
•
Illumination may not turn on immediately when you angle the
watch towards your face. This does not indicate malfunction.
•
Illumination remains on for the specified duration (1.5 seconds or
2.5 seconds) only, even if you leave the watch angled towards
your face.
•
The full auto light switch is disabled automatically whenever the
battery indicator reaches Level 4.
•
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 full auto light switch
whenever you do not need illumination.
•
Keep the full 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 full auto
light switch 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 illumination, try lowering your
arm down to your side and then raise it to your face for reading.
Rotate your arm so the watch
is angled at about 40 degrees,
so you can read its face.
With the watch on your
wrist, position it parallel
with the ground.

An EL (electro luminescent) panel is used to illuminate the display
of the watch for easy reading in the dark. The full auto light switch
automatically turns on illumination whenever you angle the watch
towards your face for viewing, while it is dark.

does not indicate malfunction.
Using the Full Auto Light Switch
