through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls at high speed. This is true except when the countdown timer number
is flashing on the Countdown Timer Mode screen (page E-21).
Auto Return Features
If you leave the watch in the Alarm Mode for two or three minutes without performing
any operation, it changes to the Timekeeping Mode automatically.
If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch exits the setting screen automatically.
To turn the button operation tone on and off
In any mode (except when a setting screen is on the
display), hold down C to toggle the button operation tone

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.
Illumination Precautions
Illumination loses power after very long use.
Illumination may be hard to see when viewed under direct sunlight.
Illumination turns off automatically whenever an alarm sounds.
Frequent use of illumination runs down the battery.
World Time
The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
All World Time Mode times are calculated from the current Home City time in the
Timekeeping Mode using UTC time differential values.
The UTC differential 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 “Universal Time Coordinated”, 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.

In December 2007, Venezuela changed its offset from –4 to –4.5. Note,
however, that this watch displays an offset of –4 (the old offset) for the CCS
(Caracas, Venezuela) city code.
** The above is current as of June 2013. This watch does not reflect the change
in the Moscow (MOW) time offset to +4. Because of this, you should leave the
summer time setting turned on (which advances the time by one hour) for Moscow
(MOW).
This table shows the city codes of this watch.
The rules governing global times (UTC offset and GMT differential) and summer
time are determined by each individual country.
