• The Moon phase indicator shows the Moon as viewed at noon from a position in the
Northern Hemisphere looking south. Note that at times the image shown by the
Moon phase indicator may differ from that of the actual Moon in your area.
• The left-right orientation of the Moon phase is reversed when viewing from the
Southern Hemisphere or from a point near the equator.
Moon Phases and Moon Age
The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon
appears to wax and wane as the relative positioning of the Earth, Moon, and Sun
changes. The greater the angular distance between the Moon and the Sun,* the more
we see illuminated.
*
The angle to the Moon in relation to the direction at which the Sun is visible from the
Earth.
This watch performs a rough calculation of the current Moon age starting from day 0
of the moon age cycle. Since this watch performs calculations using integer values
only (no fractions), the margin for error of the displayed Moon age is
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.
• The multi-function alarms and Countdown Timer Mode
alarm will sound even if the button operation tone is
turned off.
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
on ( not displayed) and off ( displayed).
• Holding down C to turn the button operation tone on or
off also causes the watch's current mode to change.
• The
indicator is displayed in all modes when the
bxDton operation tone is turned off.
Auto Return Features
• If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically exits the setting screen.
• If you leave the watch in the Fishing/Hunting Mode, Alarm Mode, and Hand setting
Mode for two or three minutes without performing any operation, it automatically
changes to the Timekeeping Mode.
Scrolling
The B 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.
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.
Illumination Precautions
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination automatically turns off whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
