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 startle 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 (auto light switch on indicator displayed) and off (auto light switch on indicator not displayed).

In order to protect against runnning down the battery, the auto light switch will turn off automatically 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.

Auto Return Features

The watch automatically returns to the Timekeeping Mode if you do not perform any operation under the conditions described below.

For two or three minutes in the Data Bank or Alarm Mode

For six or seven minutes in the Calculator Mode

If you do not perform any operation for two or three minutes while a setting or input screen (one with flashing digits or a cursor) is displayed, the watch will automatically exit the setting or input screen.

Scrolling

The B and C buttons, and [+] and [÷] keys 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.

Illumination Precautions

Keypad keys are disabled and do not input anything while the display is illuminated.

Illumination may be hard to see when viewed under direct sunlight.

Illumination automatically turns off whenever an alarm sounds.

Frequent use of illumination shortens the battery life.

Initial Screens

When you enter the Data Bank, Calculator, 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 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.

E-46

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.

More than 15 degree

Illumination may not turn on if the face of the watch is

too high

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 specify the illumination duration” on

 

page E-44), even if you keep the watch pointed towards

 

your face.

 

E-47

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 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, illumination does not turn on until about one second after you turn the face of the watch towards you. This does not indicate malfunction.

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.
