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.

About This Manual

• Depending on the model of your watch, digital display text appears

either as dark ﬁ gures on a light background, or light ﬁ gures on a dark background. All examples in this manual are shown using dark ﬁ gures on a light background.

• Button operations are indicated using the letters shown in the

illustration.

• Note that the product illustrations in this manual are intended for

reference only, and so the actual product may appear somewhat different than depicted by an illustration.

Important!

• Your watch’s Altimeter Mode calculates relative altitude based on changes in barometric pressure

measurement by its pressure sensor. For more information, see page E-59 and E-73.

• Immediately before embarking or otherwise taking altitude readings, be sure to specify a reference

altitude. If you don’t the readings produced by the watch probably will not be very accurate. For more information, see “To specify a reference altitude value” (page E-66).

• 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. For more information, see “To perform bidirectional calibration” (page E-38).

Important!

• Allowing the watch to become very hot can cause its liquid crystal display to black out. 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-13) 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

You can get an idea of the watch’s power level by observing the battery power indicator on the display.

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

• At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery

reaches Level 2 (M) after falling to Level 5, reconﬁ gure the current time, date, and other settings.

• Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).

• Leaving the watch exposed to direct sunlight or some other very strong light source can cause the

battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.

• All data stored in memory is deleted, and the current time and all other settings return to their initial

factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.

Power Recovery Mode

• Performing multiple sensor, illumination, or beeper operations during a short period may cause all of

the battery power indicators (H,M, and L) to start ﬂ ashing on the display. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and sensor operations will be disabled until battery power recovers.

• Battery power will recover in about 15 minutes. At this time, the battery power indicators (H,M,L) will

stop ﬂ ashing. This indicates that the functions listed above are enabled again.

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-30) 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:

LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW Anthorn (England), Mainﬂ ingen (Germany)

When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.

• For information about enabling and disabling power saving, see “To turn Power Saving on and off”

(page E-102).

• There actually are two sleep state levels: “display sleep” and “function sleep”.

• 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 2012, 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

Radio-controlled Atomic Timekeeping Precautions

• Strong electrostatic charge can result in the wrong time setting.

• Even if a receive operation is successful, certain conditions can cause the time setting to be off by up

to one second.

• The watch is designed to update the date and day of the week automatically for the period January 1,

2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed starting from January 1, 2100.

• If you are in an area where signal reception is not possible, the watch keeps time with the precision

noted in “Speciﬁ cations”.

• The receive operation is disabled under any of the following conditions.

– While power is at Level 3 (L) or lower (page E-10) – While the watch is in the power recovery mode (page E-11) – While a direction, barometric pressure/temperature, or altitude reading operation is in progress – When the watch is in the function sleep state (“Power Saving”, page E-13) – While barometric pressure change indicator is being measured – While a trek log updating is enabled – While a countdown timer operation is in progress (page E-89)

• A receive operation is cancelled if an alarm sounds while it is being performed.

• The Home City setting reverts to the initial default of

drops to Level 5 or when you have the rechargeable battery replaced. If this happens, change the Home City to the setting you want (page E-28) .

During manual receive, the signal level indicator displays the signal level as shown below.

Weak (Unstable) Strong (Stable)

The level indication will change in accordance with reception conditions while reception is being performed. As you watch the indicator, keep the watch in a location that best maintains stable reception.

• Even under optimum reception conditions, it can take about 10

seconds for reception to stabilize.

• Note that weather, the time of day, surroundings, and other factors all

can affect reception.

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.

• 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.

Using the Digital Compass While Mountain Climbing or Hiking

This section provides three practical applications for using the watch’s built-in digital compass.

• 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.

• Finding the bearing to an objective

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.) 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-38).

3. While in the Timekeeping Mode or in any of the sensor modes, press

to take a compass reading.

4. While direction angle readings are in progress, press E to record the currently displayed direction in Bearing Memory.

5. Now you can advance while monitoring the Bearing Memory pointer to ensure that it remains in the 12 o’clock position.

• Pressing E while the Be aring Mem ory direc tion angle val ue and

Bearing M emory p ointer are on th e display will cle ar the Bea ring Memor y data you saved i n step 3 and save the cu rrent directi on reading in Bearing Memory.

Note

• When mountain climbing or hiking, conditions or geographic

contours m ay make it impos sible for you to ad vance in a strai ght line. If this ha ppens, retur n to step 1 and save a ne w direction to the objective.

E-45

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.

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.

E-56

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.

To calibrate the pressure sensor and the temperature sensor

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. During a trek, keep checking the readings produced by the watch against altitude information provided by markers and other information, and update the reference altitude value as required.

• Reading error can be caused by changes in barometric pressure, atmospheric conditions, and

elevation.

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

Internet, etc.

To specify a reference altitude value

The Altimeter Mode screen has an altitude differential value that shows the change in altitude from a reference point you specify. The altitude differential value is updated each time the watch takes an altitude reading.

How does the altimeter work?

Generally, air pressure decrease 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.

How the Altimeter Measures Altitude

The altimeter can measure altitude based on its own preset values (initial default method) or using a reference altitude speciﬁ ed by you.

When you measure altitude based on preset values

Data produced by the watch’s barometric pressure sensor is converted to approximate altitude based on ISA (International Standard Atmosphere) conversion values stored in watch memory.

When you measure altitude using a reference altitude speciﬁ ed by you

After you specify a reference altitude, the watch uses that value to convert barometric pressure readings to altitude (page E-66).

• When mountain climbing, you can specify a reference altitude value in

accordance with a marker along the way or altitude information from a map. After that, the altitude readings produced by the watch will be more accurate than they would without a reference altitude value.

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 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.

Precautions Concerning Simultaneous Altitude and Temperature 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 temperature readings, keep the watch at as stable a temperature as possible. Changes in

temperature can affect temperature readings. See product speciﬁ cations (page E-109) for sensor accuracy information.

• 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-97), 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

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-38).

• Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel

beam, overhead wires, etc., or an attempt to take direction readings on a train, boat, etc. Move away from large metal objects and try again. Note that digital compass operation cannot be performed inside a train, boat, etc.

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.

The display shows the ERR indicator when I check the result of the latest receive operation.

* As of December 2012, 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.
