Auto Return Feature
If you leave a screen with flashing digits on the display for two or three minutes without
performing any operation, the watch automatically saves any settings you have made
up to that point and exits the setting screen.
Data and Setting 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.
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 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.
•
The year can be set in the range of 2000 to 2039.
•
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 power drops to Level 4.
Backlight 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.
•
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.
•
The backlight automatically turns off whenever an alarm sounds.
•
Frequent use of the backlight shortens the battery operating time.
Auto light switch precautions
•
Wearing the watch on the inside of your wrist, as well as movement or vibration of
your arm can cause the auto light switch to activate and illuminate 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.
•
The backlight may not light 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.
•
The backlight 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 the backlight
does not light, 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.
More than 15 degrees
too high

Under certain conditions, the backlight may not light until about one second after you
turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.
•
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.
