• For information about setting the watch up to indicate magnetic north or true

north, see “Magnetic Declination Correction” (page E-37).

3. Determine your location and destination by checking the map and the geographic

contours around you.

E-34

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!

• 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.

• 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.

E-35

Bidirectional Calibration

• 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.

Magnetic Declination Calibration

• You can use this method to specify a magnetic declination value, which sets the

digital compass up to take magnetic north or true north readings.

Precautions about bidirectional calibration

• 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.

• Do not move the watch while calibration of either direction is in progress.

• 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.

E-36

To perform bidirectional calibration

1. In the Digital Compass Mode, hold down A for two

seconds.

• This will cause the bidirectional calibration screen to

appear on the digital display.

• The second hand will move to 12 o’clock. This

causes an arrow ( ) symbol to fl ash on the left

side of the digital display and -1- to be displayed to

indicate that the watch is ready for calibration of the

fi r s t d i r e c t i o n .

2. Place the watch on a level surface facing any direction

you want, and press B to calibrate the fi rst direction.

•- - - will remain on the digital display while

calibration is in progress. OK will appear when

fi rst direction calibration is complete. About one

second after that, the fl ashing arrow will change to

point downwards ( ) and -2- will be displayed. This

means that the watch is ready for calibration of the

second direction.

E-37

3. Rotate the watch 180 degrees.

4. Press B again to calibrate the second direction.

•- - - will remain on the digital display while

calibration is in progress. OK will appear when

second direction calibration is complete.

• If ERR appears on the digital display, press B

again to restart calibration.

• Magnetic Declination Correction

With magnetic declination correction, you input a magnetic declination angle

(difference between magnetic north and true north), which allows the watch to

indicate true north. You can perform this procedure when the magnetic declination

angle is indicated on the map you are using. Note that you can input the declination

angle in whole degree units only, so you may need to round off the value specifi ed on

the map. If your map indicates the declination angle as 7.4°, you should input 7°. In

the case of 7.6° input 8°, for 7.5° you can input 7° or 8°.

E-38

To perform magnetic declination correction

1. In the Digital Compass Mode, hold down A for two

seconds.

• This will cause the bidirectional calibration screen

to appear on the digital display.

2. Press C to display the magnetic declination setting

screen (DEC).

3. Use D (East) and B (West) to change the settings.

•

The following explains magnetic declination angle

direction settings.

Digital Compass Precautions

Magnetic North and True North

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.

• Magnetic north is the north that is indicated by the

needle of a compass.

• True north, which is the location of the North Pole of the

Earth’s axis, is the north that is normally indicated on

maps.

• 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.

E-41

Location

• 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.).

• Accurate direction readings are impossible while in a train, boat, air plane, etc.

• 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.

E-42

Storage

• 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.).

• Whenever you suspect that the watch may have become magnetized, perform the

procedure under “To perform bidirectional calibration” (page E-36).

E-43

Thermometer

This watch uses a temperature sensor to take temperature readings.

To enter and exit the Thermometer Mode

1. In the Timekeeping Mode or Digital Compass Mode,

press D.

•THERMO will appear on the digital display for about

one second indicating that temperature readings

are being taken. After that, the measurement result

will appear.

• The watch will take temperature readings every fi ve

seconds for one or two minutes.

• To restart temperature readings, press D.

2. Press C to return to the Timekeeping Mode.

• If you do not perform any button operation for one

or two minutes after temperature measurement is

complete, the watch will automatically return to the

Timekeeping Mode.

E-44

Temperature

• Temperature is displayed in units of 0.1°C (or 0.2°F).

• The displayed temperature value changes to --.- °C (or °F) if a measured

temperature falls outside the range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The

temperature value will reappear as soon as the measured temperature is within the

allowable range.

Display Units

You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature

value. See “To specify temperature unit” (page E-47) for more information.

Temperature Sensor Calibration

The watch’s temperature sensor is calibrated at the factory and normally requires no

further adjustment. If you notice serious errors in the temperature readings produced

by the watch, you can calibrate the sensor to correct the errors.

E-45

Important!

• Incorrectly calibrating the temperature sensor can result in incorrect readings.

Carefully read the following before doing anything.

– Compare the readings produced by the watch with those of another reliable and

accurate thermometer.

– If adjustment is required, remove the watch from your wrist and wait for 20 or 30

minutes to give the temperature of the watch time to stabilize.

To correct the temperature value

You can correct the temperature readings displayed by

the watch in accordance with another measuring

instrument for more accurate readings.

1. In the Thermometer Mode, hold down A until the

current temperature value fl ashes on the digital display.

This is the setting screen.

E-46

2. Use D (+) and B (–) to calibrate the temperature value with the reading of another

instrument.

• Each press of a button changes the temperature value in units of 0.1°C (0.2°F).

• To return the currently fl ashing value to its initial factory default setting, press

B and D at the same time. OFF will appear at the fl ashing location for about

one second, followed by the initial default value.

3. Press A to return to the Thermometer Mode.

Thermometer Precautions

• Temperature measurements are affected by your body temperature (while you are

wearing the watch), direct sunlight, and moisture. To achieve a more accurate

temperature measurement, remove the watch from your wrist, place it in a well

ventilated location out of direct sunlight, and wipe all moisture from the case. It

takes approximately 20 to 30 minutes for the case of the watch to reach the actual

surrounding temperature.

• When taking temperature readings, it is best to remove the watch from your wrist in

order to eliminate the effects of body heat. Remove the watch from your wrist and

allow it to hang freely from your bag or in another location where it is not exposed

to direct sunlight.

Troubleshooting

Time Setting

■ Why is the current time setting off by a couple of hours?

Your Home City setting may be wrong (page E-17). Check your Home City setting and

correct it, if necessary.

■ Why is the current time setting off by one hour?

You may need to change your Home City’s standard time/daylight saving time (DST)

setting. Use the procedure under “To change the current time and date settings” (page

E-22) to change the standard time/daylight saving time (DST) setting.

Sensor modes

■ Why can’t I change the temperature unit setting?

The temperature unit setting is always Celsius (°C) whenever TOKYO is selected as

the Home City. In this case, the setting cannot be changed.

E-71

■ Why does “ERR” appear while a sensor operation is in progress?

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 digital

display and sensor operations will be disabled.

Direction Reading and

Temperature Measurement

• If ERR appears while a measurement operation is being performed in a sensor

mode, restart the measurement. If ERR appears on the digital display again, it can

mean there is something wrong with the sensor.

• If

ERR

keeps appearing during measurement, it can mean there is a problem with

the applicable sensor.

E-72

■ Why does “ERR” appear on the digital display following bidirectional

calibration?

If - - - appears and then changes to

ERR

(error) on the calibration screen, it means

that there is something wrong with the sensor.

• If

ERR

disappears after about one second, try performing the calibration again.

• If

ERR

keeps appearing, contact your original dealer or nearest authorized CASIO

distributor to have the watch checked.

Whenever you have a sensor malfunction, take the watch to your original dealer or

nearest authorized CASIO distributor as soon as possible.

■ What causes incorrect direction readings?

• Incorrect bidirectional calibration. Perform bidirectional calibration (page E-36).

• 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 large metal objects and try

again.

E-73

■ What causes different direction readings to produce different results at the

same location?

Magnetism generated by nearby high-tension wires is interfering with detection of

terrestrial magnetism. Move away from the high-tension wires 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-74

Battery

■ Why is the low battery alert fl ashing?

Battery power is low. Watch operations are disabled while

the low battery alert is fl ashing on the digital display.

If the low battery alert disappears after battery power

recovers but then starts to fl ash again after a short while,

it means that you need to have the watch’s battery

replaced.
