ENGLISH

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-66).

• 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.)

Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Whenever you are not wearing the watch, leave it in a location where it is exposed to light.

• Best charging performance is

achieved by exposing the watch to the strongest light available.

Warning! Leaving the watch in bright light for charging can cause it to become quite hot. 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.

• On the dashboard of a car parked in direct sunlight

• Too close to an incandescent lamp

• Under direct sunlight

E-14

When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing.

• The watch may enter a sleep state

(page E-19) if its face is blocked by your sleeve even only partially.

Important!

• Allowing the watch to become very hot can cause its liquid crystal display to go blank (totally black or

totally white, depending on the watch model). The appearance of the LCD should become normal again when the watch returns to a lower temperature.

• Turn on the watch’s Power Saving function (page E-19) and keep it in an area normally exposed to

bright light when storing it for long periods. This helps to ensure that power does not run down.

• 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. Expose the watch to bright light whenever possible.

Power Levels

In any mode, hold down B for at least two seconds. The battery power indicator will appear on the digital display, and then the watch will enter the Timekeeping Mode. You can get an idea of the watch’s power level by observing the battery power indicator on the display.

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 Date Settings Manually” (page E-36) 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.

If your Home City Code setting is this:

LONDON (LON), PARIS (PAR), ATHENS (ATH) Anthorn (England), Mainﬂ ingen (Germany)

HONG KONG (HKG) Shangqiu City (China)

TOKYO (TYO) Fukushima, Fukuoka/Saga (Japan)

NEW YORK (NYC), CHICAGO (CHI), DENVER (DEN), LOS ANGELES (LAX), ANCHORAGE (ANC), HONOLULU (HNL)

Important!

• The areas covered by

conditions may cause reception problems.

E-20

• Even when the watch is within range of a transmitter, signal reception may be impossible due to the

effects of geographic contours, structures, weather, the time of year, the time of day, radio interference, etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the inﬂ uence of the conditions listed above becomes even greater.

• Signal reception may not be possible at the distances noted below during certain times of the year or

day. Radio interference may also cause problems with reception. Mainﬂ ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles) Fort Collins (United States) transmitter: 600 miles (1,000 kilometers) Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles) Shangqiu (China) transmitter: 500 kilometers (310 miles)

• As of December 2013, China does not use Daylight Saving Time (DST). If China does go to the Daylight

Saving Time system in the future, some functions of this watch may no longer operate correctly.

To get ready for a receive operation

1. Conﬁ rm that the watch is in the Timekeeping Mode. If it isn’t, use B to enter the Timekeeping Mode

(page E-31).

Note

• The barometric pressure graph is not displayed while the barometric pressure change indicator is

displayed.

• While the watch is in the Barometer Mode, the watch will update the display barometric pressure value

at regular intervals (every ﬁ ve seconds for the ﬁ rst three minutes and then every two minutes for the remainder of the hour). Since the barometric pressure graph show automatic readings taken every two hours, the graph is updated only at two-hour intervals.

• Large changes in barometric pressure may cause past readings to run off the

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.

Barometric Pressure Change Indications

Whenever your watch detects a signiﬁ cant change in air pressure readings (due to sudden ascent or descent, or to the passage of a low pressure or high pressure area), it beeps to let you know. Also, an arrow ﬂ ashes on the digital display and the small hand points to the arrow mark. All of this is intended to let you know what a signiﬁ cant pressure change has occurred so you can take any action that might be required. The barometric pressure change indicator is displayed in the Barometer Mode and while the barometric pressure graph is displayed in the Timekeeping Mode (page E-33).

• For example, you could enable the barometric pressure change indicator after arriving at a lodge or

campsite. Then, before setting out the following day, you could check for changes in barometric pressure, which will give you some idea of upcoming weather conditions.

Pressure Sensor Calibration

The pressure 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 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.

To calibrate the pressure sensor

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

2. Use A to enter the Barometer Mode ( E-31.

3. Pull out the crown. This will cause the current barometric pressure reading value to ﬂ ash on the digital display.

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-56) and “Digital Compass Precautions” (page E-60).

To take a direction reading

1. 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).

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

3. In the Timekeeping Mode or any sensor mode, press A a number of times until

Compass Mode) appears on the digital display.

• In a non- sensor mo de, hold down B for about t wo second s to enter the Ti mekeeping M ode. Nex t,

perform the above step.

• After you en ter the Digit al Compas s Mode (COMP), the watch will st art taki ng bearing rea dings.

• Starti ng a digital co mpass oper ation will cau se the seco nd hand to move mo mentaril y to the

12 o’clock positio n. Followi ng the digita l compass o peration, th e second ha nd will point in t he direction of m agnetic no rth. The b earing and dire ction angl e will appear o n the digita l display.

Important!

• If the second hand does not point exactly at 12 o’clock after you perform step 3 above, perform the

operation under “Hand Home Position Adjustment” (page E-39) to adjust it.

• 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-57) and “Location” (page E-60).

Digital Compass Readings

• 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 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 ±10 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 305 to 325 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-60) for important information about taking direction readings.

• The direction indicated by the Digital Compass is magnetic north.

You can use Magnetic Declination Correction to conﬁ gure the watch to indicate true north, if you want.

For details, see “Magnetic Declination Correction” below, “To perform magnetic declination correction” (page E-58), and “Magnetic North and True North” (page E-60).

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 select a declination angle direction and 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.

E-56

4. Press A again to calibrate the second direction.

• WAIT is shown on th e display while c alibratio n is being per formed.

When calib ration is suc cessful, th e display will sh ow OK and then cha nge to the Digi tal Compa ss Mode screen. If ERR appears on the dis play, go back to step 1 of thi s procedure.

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.

To perform bidirectional calibration

3. Rotate the crown to change the magnetic declination direction and angle setting as required.

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.

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 readings are also impossible indoors, especially inside ferroconcrete structures. This is

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

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

E-60

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.

Using the Altimeter Mode

The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor.

• 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-66) and “Altimeter Precautions” (page E-72) for

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

Getting Ready

Before actually taking an altitude reading you need to select an altitude reading interval.

Selecting the Altimeter Measurement Time and Interval

You can either of the two settings described below.

0'05":

Readings for about one hour: every second for the ﬁ rst three minutes, and then every ﬁ ve seconds for the remainder of the hour

2'00":

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-57).

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.

Advanced Altimeter Mode Operations

Use the information in this section to obtain more accurate altimeter readings, especially while mountain climbing or trekking.

Using an Altitude Differential Value

Altitude differentialAltitude differential

If you specify an altitude differential start point, the second hand of the watch will indicate the difference between the current altitude and the altitude differential start point. The displayed altitude differential value is updated each time the watch obtains a new altitude reading value.

• Depending on the currently selected display range, the allowable

range for the altitude differential value is 100 meters to –100 meters (100 meters = 328 feet), or 1,000 meters to –1,000 meters (1,000 meters = 3,280 feet).

How does the altimeter work?

Generally, air pressure decreases as altitude increases. This watch bases its altitude reading on International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization (ICAO). These values deﬁ ne relationships between altitude and air pressure.

• Note that the following conditions will prevent you from obtaining accurate readings:

When air pressure changes because of changes in the weather Extreme temperature changes When the watch itself is subjected to strong impact

There are two standard methods of expressing altitude: absolute altitude, which expresses an absolute height above sea level, and relative altitude, which expresses the difference between the altitudes of two different places. This watch expresses altitudes as relative altitude.

Regular calibration of the watch in accordance with values provided by local altitude (elevation) indications is recommended before taking readings in order to maximize reading accuracy (page E-65).

1. Use the contour lines on your map to determine the difference in altitude between your current location and your destination.

• Knowing th e differen ce in altitud e helps you deter mine your

current loc ation and how m uch furt her you need t o go to reach your destination.

2. In the Altimeter Mode, hold down C for at least two seconds to specify your current location as the altitude differential start point.

• DIFF RESET and then RESET wil l appear on th e digital disp lay,

and then the second hand will move to ±0 (±0m) to indicate the altitude differential.

3. While comparing the altitude difference you determined on the map and the watch’s altitude differential value, advance towards your destination.

• If the map shows that the difference in altitude between your

location a nd your dest ination is +8 0 meters for example, you kno w you will be nea ring your des tination wh en the displaye d altitude different ial value show s +80 meters .

Altimeter Precautions

• 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 use 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.

E-72

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 Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value. See “To specify altitude, barometric pressure, and temperature units” (page E-42).

Temperature Sensor Calibration

The temperature sensor built into the watch are 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.

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.

E-96

Illumination Precautions

• The LED that provides illumination loses power after very long use.

• 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

• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can

cause frequent activation of the auto light switch and illumination of the display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display.

• Note that wearing the watch under your sleeve while the auto light switch is turned on can cause

frequent illumination of the display and can run down the battery.

E-98

• 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-96), 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.

■

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-66).
