Illumination Precautions
• The LED that provides illumination loses power after very long use.
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
Auto Light Switch Precautions
• Wearing the dive computer on the inside of your wrist,
movement of your arm, or vibration of your arm can cause
frequent activation of the auto light switch and illumination of the
display. To avoid running down the battery, turn off the auto light
switch whenever engaging in activities that might cause frequent
illumination of the display.
• Note that wearing the dive computer under your sleeve while the
auto light switch is turned on can cause frequent illumination of
the display and can run down the battery.
• Illumination may not turn on if the face of the dive computer is
more than 15 degrees above or below parallel. Make sure that
the back of your hand is parallel to the ground.
• Illumination turns off after the preset illumination duration (page
81), even if you keep the dive computer pointed towards your
face.
• Static electricity or magnetic force can interfere with proper
operation of the auto light switch. If illumination does not turn
on, try moving the dive computer back to the starting position
(parallel with the ground) and then tilt it back towards your face
again. If this does not work, drop your arm all the way down so it
hangs at your side, and then bring it back up again.
