Warning!
•
Always make sure you are in a safe place whenever you are reading the display of the watch
using the auto light switch. Be especially careful when running or engaged in any other activity
that can result in accident or injury. Also take care that sudden illumination by the auto light
switch does not startle or distract others around you.
•
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, unintended operation
of the auto light switch can create a distraction, which can result in a traffi c accident and serious
personal injury.

is below a certain level. Illumination does not turn on under bright light.
• The auto light switch is always disabled, regardless of its on/off setting, when any one of the following
conditions exists.
While an alarm is sounding
During sensor measurement
While a bearing sensor calibration operation is being performed in the Compass Mode
While a receive operation is in progress in the Receive Mode
While a hand home position adjustment operation is in progress

charging.
The following guidelines give an idea of the charging time required to recover from a single illumination
operation.
Approximately fi ve minutes exposure to bright sunlight coming in through a window
Approximately 50 minutes exposure to indoor fl uorescent lighting
• 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 watch 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. To avoid running down the battery,
turn off the auto light switch whenever engaging in activities that might cause frequent illumination.
• Note that wearing the watch under your sleeve while the auto light switch is turned on can cause
frequent illumination and can run down the battery.
• Illumination may not turn on if the face of the watch 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 E-91), even if you
keep the watch 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 watch 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.
• You may notice a very faint clicking sound coming from the watch when it is shaken
back and forth. This sound is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.
