About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on for about one second,
whenever you position your wrist as described below in any mode.
Moving the watch to a position that is parallel to the ground and then tilting it towards
you more than 40 degrees causes the backlight to turn on.

Warning!
• Always make sure you are in a safe place whenever you are reading the
display of the watch using the auto light switch. Be especially careful when
running or engaged in any other activity that can result in accident or injury.
Also take care that sudden illumination by the auto light switch does not
surprise or distract others around you.
• When you are wearing the watch, make sure that its auto light switch is turned
off before riding on a bicycle or operating a motorcycle or any other motor
vehicle. Sudden and unintended operation of the auto light switch can create a
distraction, which can result in a traffic accident and serious personal injury.
To turn the auto light switch on and off
In the Timekeeping Mode, hold down D for about two seconds to toggle the auto light
switch on (

It also contains important precautions and notes about the various features and
functions of this watch.
Moon Phase Indicator
The Moon phase indicator of this watch indicates the current phase of the Moon as
shown below.

• 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 which it appears to wax and
wane due to how the Sun illuminates the Moon and the relative positioning of the
Earth, Moon, and Sun. The greater the angular distance between the Moon and the
Sun,
the more we see illuminated.

Earth.
This watch perform a rough calculation of the current Moon age starting from
day 0 of the moon age cycle. The actual Moon age average cycle is 29.53
days, but this can vary anywhere from –1 day to +1 day for specific months.
Since this performs calculations using integer values only (no fractions), the
margin for error of the displayed Moon age is ±2 days.
Tide Graph
The black bar on the watch's tide graph indicates the current tide.
Low tide
Tidal Movements
Tides are the periodic rise and fall of the water of oceans, seas, bays, and other
bodies of water caused mainly by the gravitational interactions between the Earth,
Moon and Sun. Tides rise and fall about every six hours. The tide graph of this watch
indicates tidal movement based on the Moon's transit over a meridian and the lunitidal
interval. The lunitidal interval differs according to your current location, so you must
specify a lunitidal interval in order to obtain the correct tide graph readings.
Lunitidal Interval
Theoretically, high tide is at the Moon's transit over the meridian and low tide is about
six hours later. Actual high tide occurs somewhat later, due to factors such as
viscosity, friction, and underwater topography. Both the time differential between the
Moon's transit over the meridian until high tide and the time differential between the
Moon's transit over the meridian until low tide are known as the "lunitidal interval."
When setting the lunitidal interval for this watch, use the time differential between the
Moon's transit over the meridian until high tide.
Auto Return Feature
If you leave a screen with flashing digits on the display for two or three minutes without
performing any operation, the watch automatically saves any settings you have made
up to that point and exits the setting screen.
