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.

• 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.
