Digital Compass

A built-in bearing 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” fo r some real-life examples of how to use this feature.

Digital Compass Precautions

This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that nor th 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.

To perform magnetic declination correction

Magnetic declination angle direction

Magnetic declination angle value

1. In the Digital Compass Mode, hold down E

for about two seconds until the magnetic declination angle value starts to flash. This is the setting screen.

2. Use A (+) and C (–) to change the magnetic

declination angle value.

3. Press D to move the flashing to the magnetic

declination correction direction setting (OFF, E, W).

• This will cause the magnetic declination angle direction setting to flash.

4. Use A to cycle the direction setting between the following options.

• OFF: No magnetic declination correction

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

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

• The illustration above, 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.

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

• Selecting OFF for the magnetic declination angle direction causes the watch’s magnetic declination angle value to change to

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.

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

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.

4. After setting the map, keep the map and watch pointed in the same direction as you press E to record the currently displayed direction in Bearing Memory.

• See “Bearing Memory” for more information.

5. Now you can advance while monitoring the indicator (indicating the direction stored in Bearing Memory) to ensure that it remains in the 12 o’clock position.

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.

Direction angle of current reading

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. 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 map aligned with the readings being produced 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.

3. 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.

• The indicator (indicating the direction stored

in Bearing Memory) and the direction of the watch’s 12 o’clock position will disappear from the display about 20 seconds after you perform a compass reading by pressing C. If this happens, press C again to take a new reading and to display the indicator (indicating the direction stored in Bearing Memory).

Barometer/Thermometer

This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature.

• You can calibrate the pressure sensor and the temperature sensor if you suspect that readings are incorrect.

To take barometric pressure and temperature readings
