•The
•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 turns off automatically whenever an alarm sounds.

More than 15 degrees | • Illumination may not turn on if the face of the watch is | |
more than 15 degrees above or below parallel. Make | ||
too high | ||
sure that the back of your hand is parallel to the ground. | ||
| ||
| • Illumination turns off in about one 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.
