Operation Guide 3319/3781
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.
" 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 watchOs 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 watchOs batteries replaced.
World Time
" The World Time Mode times are calculated from the current Home City time setting
in the Timekeeping Mode, using the Greenwich Mean Time (GMT) differentials
associated with each city code.
" The GMT differential is a value that indicates the time difference between Greenwich
Mean Time and the time zone where a city is located.
" GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC) data.
Illumination Precautions
" The electro-luminescent panel that provides illumination loses power after very long
use.
" Display illumination 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.
" Illumination automatically turns off whenever an alarm sounds.
" Frequent use of the light shortens the battery life.
Auto light switch precautions
" Avoid wearing the watch on the inside of your wrist.
More than 15 degrees
too highDoing 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.
" 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 or three seconds, 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.
