To take a temperature reading

In the Digital Compass/Thermometer Mode, press D. • This will display the temperature reading.

• After the first reading, the watch will continue to take

		readings every two seconds for about 10 seconds.
		• After the temperature reading is complete, the
		temperature display will show “- -. -”.
		• To perform temperature readings for another 10
		seconds, press D again.
Temperature		• The temperature is displayed in units of 0.1°C (or 0.2°F).

•The display range of the thermometer screen is –10.0°C to 60.0°C (or 14.0°F to 140.0°F). The temperature display will show xxx if a temperature reading is outside the allowable range.

Important!

•Sudden temperature changes can affect pressure sensor readings.

•Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, 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 actual surrounding temperature.

Temperature Sensor Calibration

The temperature sensor built into the watch is calibrated at the factory, and normally does not need any adjustment. However, if you feel that readings being produced by the watch are not correct for some reason, you can calibrate the temperature sensor to correct them.

Important!

•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.

To calibrate the temperature sensor

1. In the Digital Compass/Thermometer Mode, hold down Auntil the indicator at the 12 o’clock position starts to

flash.

2. Press C twice and the current temperature calibration

value will flash on the display. This is the temperature

sensor calibration screen.

3. Use D(+) and B(–) to change the calibration value.

Digital Compass

The watch takes digital compass readings automatically whenever you enter the Digital Compass/Thermometer Mode. In addition, you can take readings manually by performing the procedure below.

•See “Digital Compass Precautions” for important information about using the digital compass.

•You can calibrate the direction bearing if you think readings are wrong for some reason.

•For a digital compass practical example, see “Using the Digital Compass While Mountain Climbing or Hiking”.

To take a direction reading

1. While the watch is in the Digital Compass/Thermometer

	12 o’clock	North	Mode, place it on a flat surface, or if you are wearing
			the watch, make sure that your wrist is horizontal (in
	position	pointer
			relation to the horizon).

2.Point the 12 o’clock position of the watch in the direction you want to measure.

3.Press Dto start a Digital Compass measurement operation.

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

Angle value (in degrees)

display.

• A pointer on the display indicates magnetic north.

sensor calibration is required due to either of the reasons described below. When this happens, perform the procedure under “Calibrating the Bearing Sensor”.

•It’s been 100 days since the last bearing sensor calibration.

•The watch’s battery was replaced.

•While the watch is taking compass readings, it displays a direction angle and a direction indicator, all of which change dynamically when the watch is moved. After the compass operation is complete, the direction pointer disappears from the display, and the direction angle and direction indicator both show “- - -”. Use the direction indicators imprinted on the bezel to record the indicated direction. For details, see “Using the Digital Compass While Mountain Climbing or Hiking”.

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 B). The measurement operation resumes for its remaining duration after the operation that caused it to pause is finished.

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

	Direction	Meaning	Direction	Meaning	Direction	Meaning	Direction	Meaning

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

Digital Compass Precautions

This watch features a built-in magnetic 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 also should 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 also are impossible indoors, especially inside ferro-concrete 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

If you feel that direction readings being produced by the watch are not correct for some reason, you can calibrate the bearing sensor to correct them. You can use either of two methods to calibrate the bearing sensor: bearing sensor correction or magnetic declination correction.

You also need to calibrate the bearing sensor if 100 days pass without calibration, and after you have the watch’s battery replaced. The message will appear on the display to remind you to calibrate.

•Bearing Sensor Correction

With bearing sensor correction, you rotate the watch in accordance with the movement of an on-screen indicator. Doing this will recalibrate the magnetic sensor of the watch with magnetic North for the area where you are located.

•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°.
