� 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. � The backlight remains lit for about two seconds from the point you press the button, even if it is already lit when you press the button. If you keep the button depressed for two seconds or more, the backlight automatically turns off. � Frequent use of the backlight shortens the battery life. Auto light switch precautions � In order to protect against running down the battery, the auto light switch automatically turns off approximately six hours after you turn it on. � Avoid wearing the watch on the inside of your wrist. Doing 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.

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.
