•The light part of the Moon phase indicator shows the part of the Moon that is visible in the sky during each particular phase.
•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.

Tide Graph
The black bar on the watch’s tide graph indicates the current tide.
High tide | Low tide | High 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 the 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.
Warning Indicators
Warning indicators appear whenever any of the conditions described below occur. Appearance of a warning indicator causes any measurement operation that is currently underway to stop. Warning indicators appear in the upper
display area, and this causes to replace any directional, temperature, or barometer values on the display.
Abnormal Magnetic Field Indicator
This indicator appears whenever the watch has a problem obtaining a correct direction reading. This condition could indicate that the watch is within a very high magnetic field, and so you should try moving to another location. Also, see “Digital Compass Precautions” for further information on conditions that cause errors.
Low Battery Indicator
This message indicates that battery power is too low to perform the measurement. It appears whenever battery power drops below a certain level, or when you try to perform a measurement under very cold conditions (below about
If the cause of the low battery indicator is due to use under cold conditions, normal operation should return after the watch is brought back to normal temperature.
If the cause of the low battery indicator is due to low battery power (indicated
when and appears under normal temperatures), you should have the watch’s batteries replaced as soon as possible.
Sensor Malfunction Indicator
This message flashes on the display to indicate malfunction of pressure sensor circuitry.
Note that calibrating the Digital Compass can
also cause the message to appear. In this case, the message does not indicate sensor malfunction, and the condition should be corrected when you
Important!
•If a sensor malfunctions or if battery power is low when it comes time for a measurement to be taken, the measurement value appears as xxxx on the display. In the case of barometric pressure measurement, the corresponding point on the barometric pressure graph is left blank.
•There may be cases where the (sensor malfunction) or
(low battery) message disappears from the display when you change modes. In this case, you can continue using the watch normally unless the warning indicator reappears.
Whenever you have a sensor malfunction, be sure to take the watch back to the store or dealer where you purchased it.
Auto Return Features
•If you leave the watch in the Digital Compass or Barometer/Thermometer Mode, for 1 to 2 hours without performing any operation, the watch automatically returns to the Timekeeping Mode.
•If you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch automatically saves anything you have input up to that point and exits the setting screen.
Setting Scrolling
The E and B buttons are used in various 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
•The day of the week is automatically displayed in accordance with the date (year, month, and day) settings.
•The year can be set in the range of 2000 to 2039. Going past December 31, 2039 reverts to January 1, 2000.

•The illumination provided by the backlight may be hard to see when viewed under direct sunlight.
•The watch will emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction.
•The backlight automatically turns off whenever an alarm sounds.
•The backlight remains lit for about one second from the point you press the button, even if it is already lit when you press the button. If you keep the button depressed for one second or more, the backlight automatically turns off.
•Frequent use of the backlight shortens the battery life.
