Taking Direction Readings

The watch has a magnetic sensor that makes it possible to take digital compass readings. You can use the digital compass to ﬁ nd the direction to a speciﬁ c objective and to determine your current position.

• See “Magnetic North and True North” (page E-28) for information about the two types of north. For

information about maximizing digital compass accuracy, see “Calibrating Direction Readings” (page E-24) and “Digital Compass Precautions” (page E-28).

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 any mode (except a setting mode), hold down C for 0.5 seconds.

2. Rotate the map (without moving the watch) 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. Magnetic north: Indicates north in accordance with the Earth’s magnetic ﬁ eld. True north: Indicates the direction to the North Pole.

• For inform ation abou t setting t he watch up to indica te magnetic

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.

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.

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°.

Digital Compass Precautions Magnetic North and True North

True north

Magnetic north

Earth

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-28

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.

Taking Temperature Readings

This watch uses a temperature sensor to measure temperature.

Temperature

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

• The displayed temperature value changes to

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 the temperature unit” (page E-33).

E-30

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-26).

Other

• Any ongoing digital compass operation is paused temporarily while the watch is performing an alert

operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by pressingB). The digital compass operation resumes for its remaining duration after the operation that caused it to pause is ﬁ nished.

• The auto light switch is disabled while a digital compass operation is in progress.

E-29

Temperature Sensor Calibration

The temperature sensor built into the watch is calibrated at the factory and normally require 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.

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 calibrate the temperature sensor

1. Take a reading with another measurement device to determine the exact current temperature.

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.

E-32

Using the Stopwatch

You can use the Stopwatch Mode to measure, record, and recall lap times and split times. Up to 100 lap times can be stored in memory and a record of the fastest lap time is also maintained. Though no more lap times are stored after 100 times are in memory, the fastest lap time continues to be updated as required. Starting a new elapsed time operation clears all of the memories (including fastest lap time).

What is a lap time?

A lap time is the time elapsed over a speciﬁ c segment of a race.

Example: Car race on an oval track

Lap 1

Auto light switch precautions

• Illumination may not turn on if the face of the watch is more than 15 degrees above

or below parallel. Make sure that the back of your hand is parallel to the ground.

• Illumination turns off after the preset illumination duration (page E-46), even if you

keep the watch pointed towards your face.

• Static electricity or magnetic force can interfere with proper operation of the auto

light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards your face again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again.

• You may notice a very faint clicking sound coming from the watch when it is shaken

back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.

Moving the Hands for Easy Viewing of the Digital Dials

Troubleshooting

Time Setting

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

■

Your Home City setting may be wrong (page E-13). 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-15) to change the standard time/ daylight saving time (DST) setting.

Why can’t I change the temperature unit setting?

■

The temperature unit setting is always Celsius (°C) whenever this case, the setting cannot be changed.

What causes incorrect direction readings?

■

• Incorrect bidirectional calibration. Perform bidirectional calibration (page E-26).

• 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.

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.

E-56

• This occurs during a digital compass operation when abnormal

magnetism is detected. The watch hands continue to move normally.

• Move the watch away from magnetic accessories, electric devices,

computers, and any other devices that generate strong magnetism, and try performing the sensor operation again.

• Try performing the operation again. If abnormal magnetism is not

indicated again, you will be able to perform the operation normally.

• If abnormal magnetism detection is indicated again, it may mean that

the watch case may have become magnetized or that magnetism conditions are completely different from those where you last performed bidirectional calibration. Perform bidirectional calibration using the procedure under “To perform bidirectional calibration” (page E-26).

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.
