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.

Warning !

•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 confirm 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.

ENGLISH

Important!

•Your watch’s Altimeter Mode calculates relative altitude based on changes in barometric pressure measurement by its pressure sensor. For more information, see pages E-51 and E-65.

•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-58).

•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-30).

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.

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-8

E-9

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.

Battery power indicator

	Level	Battery Power Indicator Function Status
	1	All functions enabled.
	(H)
	2	All functions enabled.
	(M)
	3	Illumination, beeper, and sensor operation
	(L)	disabled.
	4	Except for the current time and the CHG
		(charge) indicator, all functions and display
	(CHG)
		indicators disabled.

	5	– – –	All functions disabled.
• The flashing LOW indicator at Level 3 (L) tells you that battery power is very low, and that exposure to
bright light for charging is required as soon as possible.

	• 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, reconfigure the current time, date, and other settings.
E-10	E-11

•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 flashing 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 flashing. This indicates that the functions listed above are enabled again.

•If all of the battery power indicators (H, M, L) are flashing and the CHG (charge) indicator also is flashing, it means the battery level is very low. Expose the watch to bright light as soon as possible.

•Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer/ Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufficiently. This is indicated when all of the battery power indicators (H, M, L) are flashing.

•Frequent flashing of all of the battery power indicators (H, M, L) probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

•The above exposure times all are for reference only. Actual exposure times depend on lighting conditions.

•For details about the operating time and daily operating conditions, see the “Power Supply” section of the Specifications (page E-102).

Power Saving

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-94).

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

E-12	E-13

	Elapsed Time in Dark	Display	Operation
	60 to 70 minutes (display sleep)	Blank, with PS flashing	Display is off, but all functions are enabled.
	6 or 7 days (function sleep)	Blank, with PS not flashing	All functions are disabled, but timekeeping is
			maintained.

•The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.

•The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.

To recover from the sleep state

Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading (page E-90).

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

•The sensor modes are: Digital Compass Mode, Barometer/ Thermometer Mode, and Altimeter Mode.

2.Place the watch on a flat 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 the upper display to indicate that a digital compass operation is in progress.

•About one second after you press C, pointers (three graphic segments for north, one graphic segment each for south, east, and west) will appear on the display to indicate north, south, east, and west. Direction will also be indicated by literal direction indicators and by a direction angle.

Note

•If the four pointers (north, south, east, west) and the direction indicating letters do not appear on the display when you press C, it could mean that the watch is displaying bearing memory information. If this happens, press E to delete the current bearing memory contents. For more information, see “Using Bearing Memory” (page E-32).

•To return to the Timekeeping Mode, press D.

Pressing D will return to the Timekeeping Mode even is a reading operation is in progress.

Digital Compass Readings

•When you press C to start digital compass reading operation, COMP will initially appear on the display to indicate that a digital compass operation is in progress.

•After the first 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 - - - to indicate that digital compass readings are complete.

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

•The following table shows the meanings of each of the direction abbreviations that appear on the display.

E-26	E-27

	Direction	Meaning	Direction	Meaning	Direction	Meaning	Direction	Meaning

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

•See “Digital Compass Precautions” (page E-38) for important information about taking direction readings.

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 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°.

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 field, for example, calibrate in an open field.

E-28	E-29

To perform bidirectional calibration

1. In the Digital Compass Mode, hold down E for at least two seconds. First, SET Hold will flash on the display. After that, CALIBRATION will

scroll across the upper display. Keep E depressed until

CALIBRATION starts scrolling.

• At this time, the north pointer flashes at the 12 o’clock position and the display will show -1- to indicate that the watch is ready to calibrate the first direction.

2. Place the watch on a level surface facing any direction you want, and press C to calibrate the first direction.

•- - - is shown on the display while calibration is being performed. When calibration is successful, Turn 180° will appear on the display and three graphic segments ( ) will flash at 6 o’clock.

After about one second, CALIBRATION -2- will scroll across the upper display.

• If ERR-1 appears on the display, press C again to restart the direction reading operation.

3. Rotate the watch 180 degrees.

4. Press C again to calibrate the second direction.

• - - - is shown on the display while calibration is being performed. When calibration is successful, the display will show OK and then change to the Digital Compass Mode screen.

To perform magnetic declination correction

Magnetic declination angle direction value (E, W, or OFF)

Magnetic declination angle value

1.In the Digital Compass Mode, hold down E for at least two seconds.

First, SET Hold will flash on the display. After that, CALIBRATION will scroll across the upper display. Keep E depressed until CALIBRATION starts scrolling.

2.Press D.

•DEC 0° will appear on the display and then the current magnetic declination angle setting will flash on the display.

3.Use A (East) and C (West) to change the settings.

•The following explains magnetic declination angle direction settings.

OFF: No magnetic declination correction performed. The magnetic declination angle with this setting is 0°.

E: When magnetic north is to the east (east declination) W: When magnetic north is to the west (west declination)

•You can select a value within the range of W 90° to E 90° with these settings.

•You can turn off (OFF) magnetic declination correction by pressing A and C at the same time.

•The illustration, for example, shows the value you should input and the direction setting you should select when the map shows a magnetic declination of 1° West.

4.When the setting is the way you want, press E to exit the setting screen.

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

1.Press C to start a digital compass reading operation (page E-26).

•This will take an initial reading and then take readings every second for 60 seconds.

•If a bearing memory direction angle value is already displayed, it

means that there is a reading already stored in Bearing Memory. If this happens, press E to clear the Bearing Memory reading and exit the bearing memory screen before performing the above step.

To set a map and find your current location

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

2.While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.

• The reading will appear on the display after about one second.

North indicated by north pointer

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. For details, see “Calibrating the Bearing Sensor” (page E-28).

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

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” on page E-34 for information about how to perform the above step.

2.As shown in the illustration to the left, change your position so you (and the 12 o’clock position of the watch) are pointed in the direction of objective, while keeping the northerly direction indicated on the map aligned with north as indicated by the watch.

•If you find it difficult to perform the above step while keeping everything aligned, first move into the correct position (12 o’clock position of the watch pointed at the objective) without worrying about the orientation of the map. Next, perform step 1 again to set the map.

2.During the 60 seconds that digital compass readings are being taken, press E to store the current reading in Bearing Memory.

•The Bearing Memory direction angle flashes for about one second as it is stored in Bearing Memory. After that, the Bearing Memory screen (which shows the bearing memory direction angle and pointer) will appear, and a new 60-second direction reading operation will start.

•You can press C at any time while the Bearing Memory screen is displayed, to start a new

60-second direction reading operation. Doing so will display the direction angle for the direction that the 12 o’clock position of the watch is pointed. The direction angle of the current reading will disappear from the display after the 60-second direction reading operation is complete.

•During the first 60 seconds after you display the Bearing Memory screen or during a 60-second direction reading operation you triggered by pressing C while the Bearing Memory screen is on the display, the direction stored in memory is indicated by a Bearing Memory pointer.

•Pressing E while the Bearing Memory screen is displayed will clear the reading currently in Bearing Memory and start a new 60-second direction reading operation.

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 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.

•Finding the bearing to an objective

•Determining the direction angle to an objective on a map and heading in that direction

12 o’clock position

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

2.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” on page E-34 for information about how to perform the above step.

3.Next, set the map so the direction you want to travel on the map is pointed straight in front of you.

4.While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.

•The reading will appear on the display after about one second.

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.

3.While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.

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

•The direction angle value and pointer stored in Bearing Memory will remain on the display for about 60 seconds.

•To re-display the Bearing Memory direction angle value and Bearing Memory pointer, press C.

•See “Using Bearing Memory” (page E-32) for more information.

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 Bearing Memory direction angle value and Bearing Memory pointer are on the display will clear the Bearing Memory data you saved in step 3 and save the current direction reading in Bearing Memory.

Note

•When mountain climbing or hiking, conditions or geographic contours may make it impossible for you to advance in a straight line. If this happens, return to step 1 and save a new direction to the objective.

Digital Compass Precautions

Magnetic North and True North

	True north		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
	Magnetic north		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
	Earth		“declination”. The closer you get to the North Pole, the greater the
			declination angle.

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 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-30).
