Warning!
• Always make sure you are in a safe place whenever you are reading the
display of the watch using the auto light switch. Be especially careful when
running or engaged in any other activity that can result in accident or injury.
Also take care that sudden illumination by the auto light switch does not
surprise or distract others around you.
• When you are wearing the watch, make sure that its auto light switch is turned
off before riding on a bicycle or operating a motorcycle or any other motor
vehicle. Sudden and unintended operation of the auto light switch can create a
distraction, which can result in a traffic accident and serious personal injury.
To turn the auto light switch on and off
In the Timekeeping Mode, hold down L for about two seconds to toggle the auto light
switch on (
displayed) or off ( not displayed).
• In order to protect against runnning down the battery, the auto light switch is
automatically turned off approximately six hours after you turn it on. Repeat the
above procedure to turn the auto light switch back on if you want.
• The auto light switch on indicator (
) is on the display in all modes while the auto
light switch is turned on.
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 Display
Auto Display continually changes the contents of the
digital display.
To turn off Auto Display
Press any button (except for L and B) to turn off Auto
Display. This returns to the Timekeeping Mode.
To turn on Auto Display
Hold down C for about two seconds until the watch
beeps.
• Note that Auto Display cannot be performed while a
setting screen is on the display.
Auto Return Features
• After you perform any button operation (except for the backlight button) in any mode,
pressing C returns directly to the Timekeeping Mode.
• If you leave the watch in the Data Bank Mode for two or three minutes without
performing any operation, it automatically changes to the Timekeeping Mode.
• If you leave a screen with flashing digits or a cursor 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.
Scrolling
The B, C, 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 Data Bank 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 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 after you have the watch’s battery replaced.
Backlight Precautions
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The backlight automatically turns off whenever an alarm sounds.
• Frequent use of the backlight shortens the battery life.
Auto light switch precautions
• Wearing the watch on the inside of your wrist and 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.
• 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 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, 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.
