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.

Power Saving Function

When turned on, the Power Saving function automatically
enters a sleep state whenever the watch is left in an area
where lighting is dim (less than about 30 lux).
The following shows how watch functions are affected
when left in a dark place while in the sleep state.

Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.

The watch will not enter the sleep state between 6:00 AM and 10:59 PM. If the

the sleep state.

To recover from the sleep state

On/Off status

Scrolling

The 

B

 and 

D

 buttons are used in various modes and setting screens to scroll

through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.

Initial Screens

When you enter the World Time or Alarm Mode, the data you were viewing when you
last exited the mode appears first.

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 day of the week is automatically displayed in accordance with the date (year,
month, and day) settings.

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 after you have the watch’s battery replaced or when battery power drops to
Level 4.

The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Greenwich Mean Time (GMT) differential for each
city, based on your Home City time setting.

GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.

* UTC is the world-wide scientific standard of timekeeping. It is based upon carefully

maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.
The reference point for UTC is Greenwich, England.

12-hour/24-hour Timekeeping  Formats

The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.

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 no 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.

Illumination Precautions

The electro-luminescent panel that provides illumination loses power after very long
use.

The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.

Illumination automatically turns off whenever an alarm sounds.

The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.

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.

Note that wearing the watch 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 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 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.
