Take care when handling the watch to avoid burn injury. The watch can become
particularly hot when exposed to the following conditions for long periods.
x On the dashboard of a car parked in direct sunlight
x Too close to an incandescent lamp
x Under direct sunlight
Important!
x Keep the watch in an area normally exposed to bright light when storing it for long
periods. This helps to ensure that power does not run down.
x Storing the watch for long periods in an area where there is no light or wearing it in
such a way that it is blocked from exposure to light can cause power to run down.
Make sure that the watch is exposed to bright light whenever possible.
Checking the Current Power Level
Certain functions will be disabled when the power level is low. If the power level is
low, leave the watch in a location where its face (solar panel) is exposed to light.

Power Recovery Mode
The watch is designed to go into a power recovery mode that stops hand operation
temporarily whenever power suddenly drops below a certain level due to continuous
signal reception or other operations over a short period. Note that all operations are
disabled while the watch is in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal
operation after power recovers (in about 15 minutes). Putting the watch in a location
where it is exposed to light will help power to recover sooner.
Power Saving
Power Saving enters a sleep state (second hand sleep or function sleep) whenever
the watch is left for a certain period in an area where it is dark.

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
However, when using the watch outside of areas covered by time calibration signals,
you will have to adjust the settings manually as required. See “Confi guring Current
Time and Day Settings Manually” (page E-41) for more information.
This section explains how the watch updates its time settings when the city code
selected as the Home City is in Japan, North America, Europe, or China, and is one
that supports time calibration signal reception.

Example: Determining your current position
and your objective on a map
Having an idea of your current location and the
direction to your destination is important when
mountain climbing or hiking. In this example, we
show you how to plot directions on a map and
determine your current location using direction
measurements taken by the watch.
1. In the Timekeeping Mode, press A.
2. Rotate the map (without moving the watch)

E-52
x Keep the watch away from audio speakers, magnetic necklace, cell phone, and
other devices that generate strong magnetism. Exposure to strong magnetism can
magnetize the watch and cause incorrect direction readings. If incorrect readings
continue even after you perform bidirectional calibration, it could mean that your
watch has been magnetized. If this happens, contact your original retailer or an
authorized CASIO Service Center.
Bidirectional Calibration
x Use this method when using the watch to take readings in an area where magnetic
force is present, or if you notice that the readings produced by the watch are
different from another compass.
Northerly Calibration
x Use this method to calibrate the watch to detect true north (when it is known by
you).
until north on the map is aligned with north as
indicated by the watch’s second hand.
Depending on how the watch is set up, it may
be indicating magnetic north or true north.
x The x Second Hand indicates magnetic north.
x The x Second Hand will continue to move for about 20 seconds after you start
the digital compass operation as it adjusts its magnetic north reading. After that,
the hand will stop at the fi nal reading.
x To take another direction reading, press A again.
x To stop an ongoing direction reading operation and return to the Timekeeping
Mode, press C.
x If you do not perform any operation, the watch will return to normal timekeeping
after about one or two minutes.
3. Press C to return to the Timekeeping Mode.
Note
x If the z Hour Hand stops at 6 o’clock and the c Minute Hand stops at 12 o’clock,
it could mean that the watch has detected abnormal magnetism. For more
information, see “Abnormal magnetism detection is indicated.” (page E-87).
E-51
Magnetic north: Indicates north in accordance with the Earth’s magnetic fi eld.
True north: Indicates the direction to the North Pole.
x For information about setting the watch up to indicate magnetic north or true
north, see “Magnetic North and True North” (page E-60).
3. Determine your location and destination by checking the map and the geographic
contours around you.
Calibrating Direction Readings
You can use the information in this section to calibrate direction readings, which helps
to improve digital compass accuracy.
Direction Reading Calibration Methods
Important!
x To ensure correct direction readings by this watch, be sure to perform bidirectional
calibration before using it. The watch may produce incorrect direction readings if
you do not perform bidirectional calibration.
E-53
Precautions about bidirectional calibration
x You can use any two opposing directions for bidirectional calibration. You must,
however, make sure that they are 180 degrees opposite each other. Remember
that if you perform the procedure incorrectly, you will get wrong bearing sensor
readings.
x Do not move the watch while calibration of either direction is in progress.
x You should perform bidirectional calibration in an environment that is the same as
that where you plan to be taking direction readings. If you plan to take direction
readings in an open fi eld, for example, calibrate in an open fi eld.

Storage
x The precision of the bearing sensor may deteriorate if the watch becomes
magnetized. Because of this, you should store the watch away from magnets or
any other sources of strong magnetism, including: permanent magnets (magnetic
necklaces, etc.) and household appliances (TVs, personal computers, washing
machines, freezers, etc.).
x Whenever you suspect that the watch may have become magnetized, perform the
procedure under “To perform bidirectional calibration” (page E-56).

Important!
x Time calibration signal reception is disabled while the watch is in the World Time
Mode.
To view the time in another time zone
1. In the Timekeeping Mode, press C once to enter the World Time Mode.
x The b Lower Dial Hand will move to WT.
x To select the UTC zone as your World Time, simply hold down B for about three
seconds. No other operation is required.
2. Pull out the crown.
x The x Second Hand points to the currently selected World Time city code.
x The b Lower Dial Hand will indicate AT (AUTO), STD (standard time) or
DST (daylight saving time), which indicates the current daylight saving time
setting.
x If you do not perform any operation with the crown for about two minutes after
pulling it out, crown operations will become disabled and the watch hands will no
longer move when you rotate the crown. If this happens, push the crown back in
and then pull it out again.
E-64
The northerly direction can be expressed either as
magnetic north or true north, which are different from
each other. Also, it is important to keep in mind that
magnetic north moves over time.
x Magnetic north is the north that is indicated by the
needle of a compass.
x True north, which is the location of the North Pole of
the Earth’s axis, is the north that is normally indicated
on maps.
x The difference between magnetic north and true north
is called the “declination”. The closer you get to the
North Pole, the greater the declination angle.
Location
x Taking a direction reading when you are near a source of strong magnetism can
cause large errors in readings. Because of this, you should avoid taking direction
readings while in the vicinity of the following types of objects: permanent magnets
(magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.),
high tension wires, aerial wires, household appliances (TVs, personal computers,
washing machines, freezers, etc.).
x Accurate direction readings are impossible while in a train, boat, air plane, etc.
x Accurate readings are also impossible indoors, especially inside ferroconcrete
structures. This is because the metal framework of such structures picks up
magnetism from appliances, etc.
Checking the Current Time in a Different Time Zone
You can use World Time to view the current time in one of 29 time zones around the
globe. The currently selected city is called the “World Time City”.

This could be due to any one of the following causes. In all cases, the hand movement
does not indicate malfunction, and should stop shortly.
x The watch is recovering from a sleep state (page E-19).
x The period when summer time is applied in the location where you are using the
watch may be different from the period set for your currently selected Home City.
Use the procedure under “To switch between standard time and summer time
manually” (page E-39) to switch from AT (AUTO) to STD (for standard time) or DST (for
summer time).
■ The time and date settings are off.

E-86
■ What causes incorrect direction readings?
x The watch may have been exposed to magnetism. Calibrate the direction sensor.
x A nearby source of strong magnetism, such as a household appliance, a large
steel bridge, a steel beam, overhead wires, etc., or an attempt to perform direction
measurement on a train, boat, etc. Move away from such objects and try again.
■ What causes different direction readings to produce different results at the
same location?
x Magnetism generated by nearby digital noise sources (such as high-tension power
lines) can interfere with the detection of terrestrial magnetism. Move away from the
source of the digital noise and try again.
■ Why am I having problems taking direction readings indoors?
A TV, personal computer, speakers, or some other object is interfering with terrestrial
magnetism readings. Move away from the object causing the interference or take the
direction reading outdoors.
Indoor direction readings are particularly diffi cult inside ferro-concrete structures.
Remember that you will not be able to take direction readings inside of trains,
airplanes, etc.
E-88
x During digital compass operations, nearby strong
magnetism can cause an error to be indicated.
x If the error is indicated during a measurement, restart the
measurement. If an error is indicated when you restart
the measurement, it probably means that there is a
problem with the sensor or internal circuitry.
