Moon Phase Indicator

The Moon phase indicator of this watch indicates the current phase of the Moon as shown below.

Moon Age	0.0-1.8	1.9 - 5.5	5.6 - 9.2	9.3 - 12.9	13.0-16.6	16.7-20.2	20.3-23.9	24.0-27.6
	27.7- 29.5
Moon Phase	New		First		Full		Last
	Moon		Quarter		Moon		Quarter
			(Waxing)				(Waning)

•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 ±1 day.

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 Cto toggle the button operation tone on ( not displayed) and off ( displayed).

•Holding down Cto 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 Dbuttons 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.
