Scrolling

The B, C, and D buttons are used in various modes and setting screens to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed.

Initial Screens

When you enter the Data Bank or Alarm Mode, the data you were viewing when you last exited the mode appears first.

Timekeeping

•Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.

•The year can be set in the range of 2000 to 2039.

•The watch’s built-in full automatic calendar makes allowances for different month 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.

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 degree	• The backlight may not light if the face of the watch is
too high	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.
