Display Illumination
Auto light switch indicator

Timekeeping
Display illumination uses an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark. The watch�s auto light switch automatically turns on display illumination when you angle the watch for reading towards your face. � The auto light switch must be turned on (indicated by the auto light switch indicator) for it to operate. � See �Illumination Precautions� for more important information.

� 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 after you have the watch�s batteries replaced.

To illuminate the display In any mode, press B to turn on illumination. � The above operation turns on illumination regardless of the current auto light switch setting. � You can use the procedure below to select either one second or three seconds as the illumination duration. When you press B, the illumination will remain on for about one second or three seconds, depending on the current illumination duration setting. To specify the illumination duration 1. In the Timekeeping Mode, hold down A until the seconds start to flash, which indicates the setting screen. 2. Press C nine times so the illumination duration setting screen is on the display. 3. While the illumination duration setting is flashing, press D to toggle the setting between one second ( ) and three seconds ( ). 4. Press A to exit the setting screen.

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 Doing so causes the auto light switch to operate when it too high 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.

About the Auto Light Switch
While the auto light switch is enabled, illumination turns on for about one second or three seconds, whenever you position your wrist as described below in any mode. Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on.

Parallel to ground

More than 40°

Warning! � Always make sure you are in a safe place whenever you are reading 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 any mode, hold down B for about two seconds to toggle the auto light switch on (auto light switch indicator displayed) or off (auto light switch indicator not displayed). � The auto light switch indicator is on the display in all modes while the auto light switch is turned on. � In order to protect against running down the battery, the auto light switch automatically turns off approximately six hours after you turn it on.
