Illumination

This watch has an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark.
• The electro-luminescent panel that provides illumination
loses power after very long use.
• 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.
• Frequent use of illumination runs down the battery.
To turn on illumination
In any mode (except when a setting screen is on the display), press B to illuminate

any operation for about two or three minutes while in the Digital Compass/

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.
• With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
• The year can be set in the range of 2000 to 2099.
• 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.
• The times for the Timekeeping Mode and all the city codes of the World Time Mode
are calculated in accordance with each city's UTC offset.
• The UTC offset is a value that indicates the time difference between a reference
point in Greenwich, England and the time zone where a city is located.
• The letters UTC is the abbreviation for Coordinated Universal Time, which is the
world-wide scientific standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth's
rotation.
