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.
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.
• With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and the A (AM) indicator appears for times in the range
of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
• The day of the week is automatically displayed in accordance with the date (year,
month, and day) setting.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar automatically 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 power drops to Level 4.
Illumination Precautions
• The illumination provided by the light may be hard to see when viewed under direct
sunlight.
• Frequent use of the light shortens the battery operating time.
Auto light switch precautions
• The auto light switch is automatically turned off
whenever battery power is at Level 3.
• 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
illuminate the face of the watch. To avoid running down
the battery, turn off the auto light switch whenever
engaging in activities that might cause frequent
illumination of the face.
• Note that wearing the watch under your sleeve while the
auto light switch is turned on can cause frequent
illumination of the face 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 (see “To set the digital time
and date”), 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.
• 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.
