Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Button Operation Tone
The button operation tone sounds any time you press one
of the watch’s buttons. You can turn the button operation
tone on or off as desired.
• Even if you turn off the button operation tone, the
alarms, the Hourly Time Signal, the countdown alarm,
and the event timer alarm all operate normally.
To toggle the button operation tone on and off
In any mode (except when a setting screen is on the
display), hold down B to toggle the button operation tone
on ( not displayed) and off ( displayed).
• Holding down B to toggle the button operation tone on or off also causes the
watch’s current mode to change.
• is displayed in all modes when the button operation tone is turned off.
Scrolling
The 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 at high speed. This is true except when the countdown timer number
is flashing on the Countdown Timer Mode screen.
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.
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 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.
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.
Illumination Precautions
An LED (light-emitting diode) illuminates the display for easy reading in the dark. In
any mode (except when a setting screen is on the display), press L to turn on
illumination for about two seconds.
• 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.
