Moon Phase Indicator
The Moon phase indicator of this watch indicates
the current phase of the Moon as shown below. It
is based on the view of the left side of the moon
at meridian transit from the northern hemisphere
of the Earth. If the appearance of the Moon
phase indicator is reversed from the actual Moon
as viewed from your location, you can use the
procedure under “To reverse the displayed Moon
phase” to change the indicator.

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 Tide Graph calculates and graphically
represents current tide conditions in your Home City or a port city in the
vicinity of the Home City based on longitudes, lunar day length, and lunitidal
interval preset in watch memory, and on high tide times specified by you.
Tide Graph
The Tide Graph graphically represents the current tide condition using one of
three patterns that represent spring tide, intermediate tide, and neap tide, as
shown below.
Large difference between
high tide and low tide. Occurs
a few days before and after a
New Moon and Full Moon.
Medium difference between
high tide and low tide.
Small difference between
high tide and low tide. Occurs
a few days before and after
the first quarter and last
quarter of a half moon.
Tide Name Graph Description
Spring Tide
Intermediate Tide
Neap Tide
•
The Tide Graph flashes as shown below to indicate the tide range.
•
The segments on either end of the Tide Graph flash during high tide.
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”.

Auto Return Features
• The watch returns to the Timekeeping Mode automatically if you do not
perform any button operation for two or three minutes in the Tide/Moon
Data, Alarm, Data Recall, Receive, Digital Compass, or Barometer/
Thermometer Mode.
•
If you do not perform any button operation while in the Altimeter Mode, the
watch returns to the Timekeeping Mode automatically after nine or 10 hours.
• 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.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing
when you last exited the mode appears first.
Scrolling
The A and C buttons are used on the setting screen 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.
Sensor Malfunction Indicator
Subjecting the watch to strong impact can cause sensor malfunction or
improper contact of internal circuitry. When this happens,
ERR
(error) will
appear on the display and sensor operations will be disabled.
• If
ERR appears while a measurement operation is being performed in a
sensor mode, restart the measurement. If
ERR appears on the display
again, it can mean there is something wrong with the sensor.
•
Even if battery power is at Level 1 or Level 2, the Digital Compass Mode,
Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled if
there is not enough voltage available to power it sufficiently. In this case,
ERR
will appear on the display. This does not indicate malfunction, and sensor
operation should resume once battery voltage returns to its normal level.
• If ERR keeps appearing during measurement, it could mean there is a
problem with the applicable sensor.
Whenever you have a sensor malfunction, be sure to take the watch to
your original dealer or nearest authorized CASIO distributor as soon as
possible.
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 alarm, Hourly Time Signal, and Countdown
Timer Mode alarm all operate normally.
To turn the button operation tone on and off
In any mode (except when a setting screen is on
the display), hold down D to toggle the button
operation tone on (
not displayed) and off (
displayed).
• Since the D button also is the mode change button, holding it down to turn
the button operation on or off also causes the watch’s current mode to
change.
• The
indicator is displayed in all modes when the button operation tone is
turned off.

Power Saving
When turned on, Power Saving enters a sleep
state automatically whenever the watch is left for
a certain period in an area where it is dark. The
table below shows how watch functions are
affected by Power Saving.
• There actually are two sleep state levels:
“display sleep” and “function sleep”.
• Wearing the watch inside the sleeve of clothing can cause it to enter the
sleep state.
• The watch will not enter the sleep state while the digital time is between
6:00 AM and 9:59 PM. If the watch is already in the sleep state when the
digital time reaches 6:00 AM, however, it will remain in the sleep state.
• The watch will not enter the sleep state while it is in the Digital Compass,
Barometer/Thermometer, Altimeter, Receive, Countdown Timer, or
Stopwatch Mode. When the watch is left in any mode besides the
Countdown Timer and Stopwatch Mode, it will return to the Timekeeping
Mode automatically after a specific amount of time. Then if left in the dark
for the elapsed time indicated in the table above, the watch will enter the
sleep state.
