••The watch’s built-in full automatic calendar makes allowances for different month		City Code Table
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.

••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			JRS	Jerusalem

More than 15 degrees	••Illumination may not turn on if the face of the watch is more
too high	than 15 degrees above or below parallel. Make sure that the
	back of your hand is parallel to the ground.
	••Illumination turns off after the preset illumination duration
	(see “To specify the illumination duration” (page E-33)),
	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.
