Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully.

Applications

The built-insensors 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.

Keep the watch exposed to bright light

Solar cell

The electricity generated by the solar cell of the watch is stored by a built-inbattery. Leaving or using the watch where it is not exposed to light causes the battery to run down. Make sure the watch is exposed to light as much as possible.

When you are not wearing the watch on your wrist, position the face so it is pointed at a source of bright light.

You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is covered only partially.

The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will cause some watch functions to be disabled. If the battery goes dead, you will have to re-configurewatch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

Radio-controlledAtomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.

This watch is designed to pick up the time calibration signals transmitted in Germany (Mainflingen), England (Anthorn), and the United States (Fort Collins) and the time calibration signals transmitted in Japan.

Current Time Setting

This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can perform a manual procedure to set the time and date, when necessary.

The first thing you should do after purchasing this watch is to specify your Home City (the city where you normally will use the watch). For more information, see “To specify your Home City” below.

When using the watch outside the areas covered by the time signal transmitters, you will have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.

The U.S. time calibration signal can be picked up by the watch while in North America. The term “North America” in this manual refers to the area that consists of Canada, the continental United States, and Mexico.

3. Press Eto exit the setting screen.

Normally, your watch should show the correct time as soon as you select your Home City code. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night). You also can perform manual receive or you can set the time manually.

The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between city codes and transmitters, see “Time Calibration Signal Reception” and “Transmitters”.

See the maps under “Approximate Reception Ranges” for information about the reception ranges of the watch.

You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information.

Time Calibration Signal Reception

There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.

Auto Receive

With auto receive, the watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive”.

Manual Receive

Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see “To perform manual receive”.

Important!

When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side facing towards a window. Make sure there are no metal objects nearby.

Note

When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings.

Auto receive of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily.

2

Operation Guide 3070 (B)

The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.

Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.

About the Receiving Indicator

The receiving indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest. The receiving indicator is displayed while an auto or manual receive operation is in progress.

(Level 5)

Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.

Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.

Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 5 receiving indicator will remain on the display in all modes. The Level 5 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

The Level 5 receiving indicator is displayed only when the watch is able to receive both time and date data successfully. It does not appear when only time data is received.

The Level 5 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 5 receiving indicator disappears from the display each day when the first auto receive operation of the day is performed.

Digital Compass

A built-inbearing sensor detects magnetic north and indicates one of 16 directions on the display. Direction readings are performed in the Digital Compass Mode.

You can store a direction reading in Bearing Memory and display that reading as you take subsequent readings.

For more information about Bearing Memory, see “Bearing Memory”.

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

See “Using the Digital Compass While Mountain Climbing or Hiking” for some real-lifeexamples of how to use this feature.

measurement operation.

After about two seconds, the direction that the 12 o’clock position of the watch is pointing appears on the display.

Also, four pointers appear to indicate magnetic north, south, east, and west.

After the first reading is obtained, the watch continues to take direction readings automatically each second, for up to 20 seconds.

While the watch is taking compass readings, it displays a direction angle, a direction indicator, and four direction pointers, which change dynamically when the watch is moved. The direction angle, direction indicator and direction pointers all disappear from the display after the compass reading operation is complete.

Note

Note that taking a measurement while the watch is not horizontal (in relation to the horizon) can result in large measurement error.

The margin of error for the angle value and the direction indicator is ±11 degrees. If the indicated direction is northwest (NW) and 315 degrees, for example, the actual direction can be anywhere from 304 to 326 degrees.

Any ongoing direction measurement 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 pressing L). The measurement operation resumes for its remaining duration after the operation that caused it to pause is finished.

See “Digital Compass Precautions” for other important information about taking direction readings.

Digital Compass Precautions

This watch features a built-inmagnetic bearing sensor that detects terrestrial magnetism. This means that north indicated by this watch is magnetic north, which is somewhat different from true polar north. The magnetic north pole is located in northern Canada, while the magnetic south pole is in southern Australia. Note that the difference between magnetic north and true north as measured with all magnetic compasses tends to be greater as one gets closer to either of the magnetic poles. You should also remember that some maps indicate true north (instead of magnetic north), and so you should make allowances when using such maps with this watch.

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.

Storage

The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of this, you should be sure to 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 one of the calibration procedures under “Calibrating the Bearing Sensor”.

Calibrating the Bearing Sensor

You should calibrate the bearing sensor whenever you feel that the direction readings being produced by the watch are off. There are three different calibration methods available: magnetic declination correction, bidirectional calibration, and northerly 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 degree units only, so you

may need to round off the value specified 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°.

Bidirectional Calibration and Northerly Calibration

Bidirectional calibration and northerly calibration calibrate the accuracy of the direction 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. With northerly calibration, you “teach” the watch which way is north (which you have to determine with another compass or some other means).

Important!

If you want to perform both bidirectional and northerly calibration, be sure to perform bidirectional calibration first, and then perform northerly calibration. This is necessary because bidirectional calibration cancels any existing northerly calibration setting.

The more correctly you perform bidirectional calibration, the better the accuracy of the bearing sensor readouts. You should perform bidirectional calibration whenever you change environments where you use the bearing sensor, and whenever you feel that the bearing sensor is producing incorrect readings.

Operation Guide 3070 (B)

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.

Make sure that you 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 field, for example, calibrate in an open field.

--- is shown on the display while calibration is being performed. When

calibration is successful, the display will show OK and the Digital Compass Mode (with0° shown as the angle value).

If --- appears and then changes toERR (error) on the calibration screen, it means that there is something wrong with the sensor. WhenERR disappears after about one second, try performing the calibration again. IfERR keeps appearing, contact your original dealer or nearest

authorized CASIO distributor to have the watch checked.

Bearing Memory lets you store a direction reading and display that reading as you take subsequent readings.

The Bearing Memory screen displays the direction angle for the stored direction, along with an indicator in the ring around the display that also indicates the stored direction. When you take compass readings while the Bearing Memory screen is on the display, the direction angle for your current bearing (as read from the 12 o’clock position of the watch) is also shown.

To store a compass reading in Bearing Memory

1.In the Digital Compass Mode, press C to take a reading.

After the compass reading is complete, the watch will continue to take direction angle readings automatically for about 20 seconds.

2. While direction angle readings are in progress, press E.

This will cause the direction angle to flash for about one second as it is stored in Bearing Memory, and then the Bearing Memory screen will appear.

While the Bearing Memory screen is on the display, you can press C to start a 20-seconddirection reading operation that displays the direction angle for the direction that the 12 o’clock position of the watch is pointed. The direction angle of the current readings will disappear from the display after the direction reading operation is complete.

During the first 20 seconds after you display the Bearing Memory screen or during the 20-seconddirection reading operation while the Bearing Memory screen is on the display, the direction stored in memory is indicated by an indicator in the ring around the display.

Pressing E while the Bearing Memory screen is displayed will clear the direction angle currently in Bearing Memory and return to the Digital Compass Mode.

Using the Digital Compass While Mountain Climbing or Hiking

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

Setting a map and finding 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.

North indicated by north pointer

1.With the watch on your wrist, position it so the face is horizontal.

2.In the Timekeeping, Digital Compass,

Barometer/Thermometer, or Altimeter Mode, press C to take a compass reading.

The reading will appear on the display after about two seconds.

3.Rotate the map without moving the watch so the northerly direction indicated on the map matches north as indicated by the watch.

If the watch is configured to indicate magnetic north, align the map’s magnetic

north with the watch indication. If the watch has been configured with a declination to correct to true north, align the map’s true north with the watch indication.

This will position the map in accordance with your current location.

4.Determine your location as you check the geographic contours around you.

1.Set the map so its northerly indication is aligned with north as indicated by the watch, and determine your current location.

See “To set a map and find your current location” for information about how to perform the above step.

2.Set the map so the direction you want to travel on the map is pointed straight in front of you.

3.With the watch on your wrist, position it so the face is horizontal.

4.In the Timekeeping, Digital Compass, Barometer/Thermometer, or Altimeter Mode, press C to take a compass reading.

The reading will appear on the display after about two seconds.

5.Still holding the map in front of you, turn your body until north as indicated by the watch and the northerly direction on the map are aligned.

This will position the map in accordance with your current location, so the bearing to your objective is straight ahead of you.
