Operation Guide 5269

To take a direction reading

12 o’clock position

1. Point the 12 o’clock position of the watch in the

2.In the Timekeeping Mode or Thermometer Mode, keep the watch horizontal as you press B.

•COMPASS will appear on the digital display and then direction reading will start.

•After the watch completes a reading, the second hand will indicate north. The direction indicator will show a literal indicator (abbreviation) for the direction where 12 o’clock of the watch is pointed. A direction angle will also be displayed.

Starting a digital compass direction reading causes consecutive readings to be taken each second for 20 seconds. After a series of consecutive readings is complete, - - - appears in place of the literal direction indicator on the display.

•See “Digital Compass Readings” (page E-31) for information about what appears on the digital display.

Example: Determining your current position and your objective on a map

Having an idea of your current location and the direction to your destination is important when mountain climbing or hiking. In this example, we show you how to plot directions on a map and determine your current location using direction measurements taken by the watch.

1.In the Timekeeping Mode or Thermometer Mode, press

B.

2.Rotate the map (without moving the watch) until north on the map is aligned with north as indicated by the watch’s second hand.

Depending on how the watch is set up, it may be indicating magnetic north or true north.

Magnetic north: Indicates north in accordance with the Earth’s magnetic field.

True north: Indicates the direction to the North Pole.

•For information about setting the watch up to indicate magnetic north or true north, see “Magnetic Declination Correction” (page E-37).

3.Determine your location and destination by checking the map and the geographic contours around you.

Calibrating Direction Readings

You can use the information in this section to calibrate direction readings, which helps to improve digital compass accuracy.

Direction Reading Calibration Methods

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.

•Keep the watch away from audio speakers, magnetic necklace, cell phone, and other devices that generate strong magnetism. Exposure to strong magnetism can magnetize the watch and cause incorrect direction readings. If incorrect readings continue even after you perform bidirectional calibration, it could mean that your watch has been magnetized. If this happens, contact your original retailer or an authorized CASIO Service Center.

E-34

To perform bidirectional calibration

1. In the Digital Compass Mode, hold down A for two seconds.

• This will cause the bidirectional calibration screen to appear on the digital display.

• The second hand will move to 12 o’clock. This causes an arrow () symbol to flash on the left side of the digital display and -1-to be displayed to indicate that the watch is ready for calibration of the first direction.

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

•- - - will remain on the digital display while calibration is in progress. OK will appear when first direction calibration is complete. About one

second after that, the flashing arrow will change to point downwards () and -2-will be displayed. This means that the watch is ready for calibration of the second direction.

E-36

To perform magnetic declination correction

Bidirectional Calibration

•Use this method when using the watch to take readings in an area where magnetic force is present, or if you notice that the readings produced by the watch are different from another compass.

Magnetic Declination Calibration

•You can use this method to specify a magnetic declination value, which sets the digital compass up to take magnetic north or true north readings.

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-35

3. Rotate the watch 180 degrees.

4. Press B again to calibrate the second direction.

• - - - will remain on the digital display while calibration is in progress. OK will appear when second direction calibration is complete.

• If ERR appears on the digital display, press B again to restart 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°.

E-37

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

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

Magnetic declination angle value

1.In the Digital Compass Mode, hold down A for two seconds.

•This will cause the bidirectional calibration screen to appear on the digital display.

2.Press C to display the magnetic declination setting screen (DEC).

3.Use D (East) and B (West) to change the settings.

•The following explains magnetic declination angle direction settings.

OFF: No magnetic declination correction performed. The northerly magnetic declination setting (DEC) will be 0°.

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

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

• You can turn off (OFF) magnetic declination correction by pressing D and B

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 7°

West.

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