described under “To adjust home positions” (page E-44) to match the analog setting to
the digital setting.

• Check to make sure that the speed hand is not moving before you perform any
Stopwatch Mode button operation.
Specifying a Distance Value
You can use the procedure below to specify a distance value, if you want. If you
specify a distance value, the watch will calculate and indicate speed for certain
stopwatch operations.
• The distance value represents kilometers, miles, or any other distance unit you
want. Specifying a distance value of 10.0, for example, can mean 10.0 kilometers or
10.0 miles.
• No speed calculation is performed when 0.0 is specified as the current distance
value.
• For lap time readings, you can specify either the lap distance (when all the laps are
the same distance) or the total race distance.
• For split time readings, you can specify the total race distance only. Though the
watch will indicate a speed each time you take a split reading, they will be based
on the total race distance, and so they will not indicate actual intermediate split
speeds.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto Return Features
• If you leave the watch with a flashing setting on any display dial for two or three
minutes without performing any operation, the watch will exit the setting mode
automatically.
• The watch will return to the Timekeeping Mode automatically if you do not perform
any operation for two or three minutes in the Alarm Mode.
High-Speed Movement
• The D and B buttons are used to change setting in various setting modes. In
most cases, holding down these buttons will start high-speed movement.
E-46
Illumination Precautions
• Illumination may be difficult 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
• Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light
switch to operate when it is not needed, which shortens battery life. If you want to
wear the watch on the inside of your wrist, turn off the auto light switch feature.
More than 15 degrees

• 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 in about 1.5 seconds or 3 seconds,
even if you keep the watch pointed towards your face.
Initial Screens
When you enter the Stopwatch Mode, World Time Mode or Alarm Mode, the data you
were viewing when you last exited the mode will appear first in the left digital dial.
Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to
change it except when battery has replaced.
• The current time for all city codes in the Timekeeping Mode and World Time Mode
is calculated in accordance with the Coordinated Universal Time (UTC) for each
city, based on your Home City time setting.

• 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 toward 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.

* As of January 2016, the offi cial UTC
offset for Santiago, Chile (SCL) has
been changed from –4 to –3, but this
watch still uses an offset of –4 (the old
+8
+9
offset) for SCL. Because of this, you
should leave the summer time setting
turned on (which advances the time
by one hour) for the SCL time.
This table shows the city codes of this
x
watch.
• The rules governing global times (UTC
offset and GMT differential) and
summer time are determined by each
individual country.
