Casio 2575 Backlight Precautions, Auto light switch precautions

USER’S GUIDE 2575

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.

More than 15 degrees too high

•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.
