How Stopwatch Data is Stored
The following table describes how data is stored when you perform the various button
operations described on page E-10.
Stopwatch Button Operation
Start (from all zeros)
Creates a new log: current date and distance
(updated as timing progresses)
Stop
Time measurement stops, without storing data in
memory.
Re-start
Time measurement re-starts, without storing
data in memory.
Lap/Split
Creates new record: displayed lap/split times
Clear
Creates new record: displayed lap/split times
(Stopwatch display is cleared to all zeros.)
E-40
More than 15 degrees
Illumination may not turn on if the face of the watch is
too high
more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.
Illumination turns off in about one second, 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 you 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.
Under certain conditions, illumination may not turn on until about one second after
you turn the face of the watch towards you. This does not necessarily indicate
malfunction of the auto light switch.
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.

Data Store Operation
Illumination Precautions
Illumination may be hard to see when viewed under direct sunlight.
Illumination automatically turns off 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 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.
