Congratulations upon your selection of this CASIO watch.

Applications

The built-in sensors of this watch measure direction, barometric pressure, temperature and altitude. Measured values are then shown on the display. Such features make this watch useful when hiking, mountain climbing, or when engaging in other such outdoor activities.

• The measurement functions built into this watch are not intended for taking measurements that

require professional or industrial precision. Values produced by this watch should be considered as reasonable representations only.

•

When engaging in mountain climbing or other activities in which losing your way can create a dangerous or life-threatening situation, always use a second compass to conﬁ rm direction readings.

• Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss

suffered by you or any third party arising through the use of this product or its malfunction.

Warning !

E-1

Important!

• The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure

readings produced by its pressure sensor. This means that readings taken at different times at the same location may produce different altitude values due to changes in barometric pressure. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located.

• When using the altimeter of this watch for mountain climbing or other activities, it is highly

recommended that you check a map, local altitude indications, or some other source for your current correct altitude and regularly calibrate the altimeter with the latest information. For more information, see “To specify a reference altitude value” (page E-47).

• Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or other

activities, be sure always to take along another compass to conﬁ rm readings. If the readings produced by the digital compass of this watch are different from those of the other compass, perform bidirectional calibration of the digital compass to ensure more accurate readings.

• Direction readings and digital compass calibration will not be possible if the watch is in the vicinity of a

permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or electrical household appliances (TV, computer, cellphone, etc.)

Taking Direction Readings

You can use the Digital Compass Mode to determine the direction of north, and to check your bearing to a destination.

• For information about what you can do to improve digital compass reading accuracy, see “Calibrating

the Bearing Sensor” (page E-22) and “Digital Compass Precautions” (page E-27).

To take a direction reading

1. Make sure the watch is in the Timekeeping Mode or any one of the sensor modes.

• The senso r modes are: Digit al Compass M ode, Baromete r/Therm ometer Mode, a nd Altimeter

Mode.

2. Place the watch on a ﬂ at surface. If you are wearing the watch, make sure that your wrist is horizontal (in relation to the horizon).

3. Point the 12 o’clock position of the watch in the direction whose reading you want to take.

4. Press C to start.

• COMP will appear in th e upper display to ind icate that a digita l compass ope ration is in prog ress.

• About one s econd afte r you press C, pointers (thre e graphic segme nts for nort h, one graphic

segment ea ch for south, ea st, and west) will ap pear on the disp lay to indicate nor th, south, e ast, and west. Dire ction will als o be indicated by litera l direction indi cators and by a direct ion angle.

Calibrating the Bearing Sensor

You should calibrate the bearing sensor whenever you feel that the direction readings being produced by the watch are off. You can use any one of two different bearing sensor calibration methods: bidirectional calibration or magnetic declination correction.

Bidirectional Calibration

•

Bidirectional calibration calibrates the bearing sensor in relation to magnetic north. Use bidirectional calibration when you want to take readings within an area exposed to magnetic force. This type of calibration should be used if the watch becomes magnetized for any reason.

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.

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°.

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.

Important!

• If the digital display contents start to ﬂ ash after you perform a reading operation, it means that abnormal

magnetism has been detected. Move away from any potential source of strong magnetism and try taking a reading again. If the problem occurs when you try again, continue to keep away from the source of strong magnetism, perform bidirectional calibration, and then try taking a reading again. For more information, refer to “To perform bidirectional calibration” (page E-23) and “Location” (page E-27).

Digital Compass Readings

• When you press Cto start digital compass reading operation,

display to indicate that a digital compass operation is in progress.

• After the ﬁ rst reading is obtained, the watch will continue to take digital compass readings automatically

each second for up to 60 seconds. After that, the reading operation will stop automatically.

• The direction indicator and angle value will show

complete.

• The auto light switch is disabled during the 60 seconds that digital compass readings are being taken.

• The margin of error for the angle value and the direction indicator is ±11 degrees while the watch is

horizontal (in relation to the horizon). If the indicated direction is northwest (NW) and 315 degrees, for example, the actual direction can be anywhere from 304 to 326 degrees.

• Note that taking a direction reading while the watch is not horizontal (in relation to the horizon) can

result in large direction reading error.

•

You can calibrate the bearing sensor if you suspect the direction reading is incorrect.

• Any ongoing direction reading 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 pressingL). The direction reading operation resumes for its remaining duration after the operation that caused it to pause is ﬁ nished.

• See “Digital Compass Precautions” (page E-27) for important information about taking direction readings.

• 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.

To perform bidirectional calibration

1. In the Digital Compass Mode, hold down E for at least two seconds. First, scroll across the upper display. Keep E depressed until

Setting a map and ﬁ nding your current location

Having an idea of your current location is important when mountain climbing or hiking. To do this, you need to “set the map”, which means to align the map so the directions indicated on it are aligned with the actual directions of your location. Basically what you are doing is aligning north on the map with north as indicated by the watch.

• Note that map reading skills and experience are required to determine your current location and

destination on a map.

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.)

because the metal framework of such structures picks up magnetism from appliances, etc.

Bearing Memory lets you temporarily store and display a direction reading so you can use it as a reference as you take subsequent digital compass readings. The Bearing Memory screen displays the direction angle for the stored reading, along with a pointer that indicates the stored reading. When you take digital compass readings while the Bearing Memory screen is displayed, the direction angle of the current digital compass reading (as read from the 12 o’clock position of the watch) and the stored Bearing Memory direction reading will both be shown.

To store a direction angle reading in Bearing Memory

to store the current

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.

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.), concentrations of metal (metal doors, lockers, 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-23).

Barometric Pressure Change Indications

Your watch analyzes past barometric pressure readings and uses a barometric pressure change indicator to inform you about changes in pressure. If it determines there has been a signiﬁ cant change in pressure, it will beep and all of the graphic segments ( pressure change alert. This means you could start taking barometric pressure readings after reaching a lodge or camp area, and then check the watch the next morning for changes in pressure, and plan you day’s activities accordingly. Note that you can enable or disable display of the barometric pressure change indicator as desired.

Important!

• To ensure proper results, take barometric readings under conditions where the altitude remains

constant.

• A change in altitude causes a change in barometric pressure. This means that correct barometric

pressure readings are not possible while you are changing altitudes. To avoid possible confusion, it is probably best to disable the barometric pressure change indicator while you are on the move during your climb.

Pressure Sensor and Temperature Sensor Calibration

The pressure sensor and temperature sensor built into the watch are calibrated at the factory and normally require no further adjustment. If you notice serious errors in the pressure readings and temperature readings produced by the watch, you can calibrate the sensor to correct the errors.

Important!

• Incorrectly calibrating the barometric pressure sensor can result in incorrect readings. Before

performing the calibration procedure, compare the readings produced by the watch with those of another reliable and accurate barometer.

• 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.

Barometer and Thermometer Precautions

• The pressure sensor built into this watch measures changes in air pressure, which you can then apply

to your own weather predictions. It is not intended for use as a precision instrument in ofﬁ cial weather prediction or reporting applications.

• Sudden temperature changes can affect pressure sensor readings. Because of this, there may be

some error in the readings produced by the watch.

• Temperature reading are affected by your body temperature, direct sunlight, and moisture. To achieve

a more accurate temperature reading, 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 surrounding temperature.

Using the Altimeter Mode

The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor. It also saves various types of altitude records and data.

• The displayed altitude reading is a relative altitude that is calculated based on measurement of

changes in barometric pressure by the watch’s pressure sensor. This means that barometric pressure changes can cause readings taken at different times at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located.

• When using the altimeter of this watch for mountain climbing or other activities, it is highly

recommended that you check a map, local altitude indications, or some other source for your current correct altitude and regularly calibrate the altimeter with the latest information.

Important!

• See “To specify a reference altitude value” (page E-47) and “Altimeter Precautions” (page E-57) for

information about how to minimize differences between readings produced by the watch and values provided by local altitude (elevation) indications.

Using Reference Altitude Values

To minimize the chance of reading error, you should update the reference altitude value before setting off on a trek or any other activity where you plan to take altitude readings. While mountain climbing, it is highly recommended that you check a map, local altitude indications, or some other source for your current correct altitude and regularly update the reference altitude value with the latest information.

• Reading error can be caused by changes in barometric pressure, and by temperature changes due to

change in barometric pressure and/or elevation.

• Though altitude readings can be taken without setting a reference altitude, doing so may produce

readings that are very different from altitudes indicated by other altitude markers and indications.

• Before performing the procedure below, look up the altitude of your current location on a map, the

Internet, etc.

• This watch estimates altitude based on air pressure. This means that altitude readings for the same

location may vary if air pressure changes.

• Do not rely upon this watch for altitude reading or perform button operations while sky diving, hang

gliding, or paragliding, while riding a gyrocopter, glider, or any other aircraft, or while engaging in any other activity where there is the chance of sudden altitude changes.

• Do not use this watch for measuring altitude in applications that demand professional or industrial level

precision.

• Remember that the air inside of a commercial aircraft is pressurized. Because of this, the readings

produced by this watch will not match the altitude readings announced or indicated by the ﬂ ight crew.

The Effect of Temperature on Altitude Readings

For the more accurate altitude readings, leaving the watch on your wrist is recommended in order to maintain the watch at a constant temperature.

• When taking altitude readings, keep the watch at as stable a temperature as possible. Changes in

temperature can affect altitude readings.

About the Auto Light Switch

Turning on the auto light switch causes illumination to turn on, whenever you position your wrist as described below in any mode.

Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on.

Warning!

Always make sure you are in a safe place whenever you are reading the display of the watch

•

using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not startle or distract others around you.

When you are wearing the watch, make sure that its auto light switch is turned off before riding

•

on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a trafﬁ c accident and serious personal injury.

Illumination Precautions

• Illumination may be hard to see when viewed under direct sunlight.

• Illumination turns off automatically whenever an alarm sounds.

• Frequent use of illumination runs down the battery.

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-78), 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.

Low Battery Indication

A low battery indicator appears on the display when battery power is low. Have the battery replaced as soon as possible.

Troubleshooting

Time Setting

The current time setting is off by hours.

■

Your Home City setting may be wrong (page E-14). Check your Home City setting and correct it, if necessary.

Altitude Readings

Altitude readings produce different results at the same location.

■

Readings produced by the watch are different from the elevation and/or sea level altitude

■

indications in my area. (Negative sea level altitude values are produced in a location where the indicated elevation is a positive value.)

I can’t get correct altitude readings.

■

Relative altitude is calculated based on changes in barometric pressure measurement by its pressure sensor. This means that barometric pressure changes can cause readings taken at different times at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located. When using the altimeter of this watch for mountain climbing or other activities, it is highly recommended that you check a map, local altitude indications, or some other source for your current correct altitude and regularly calibrate the altimeter with the latest information. For more information, see “To specify a reference altitude value” (page E-47).

* As of June 2014, the ofﬁ cial UTC offset for

Moscow, Russia (MOW) was changed from +3 to +4, but this watch still uses an offset of +3 (the old offset) for MOW. Because of this, you should leave the summer time setting turned on (which advances the time by one hour) for the MOW time.

• The rules governing global times (GMT

differential and UTC offset) and summer time are determined by each individual country.
