The temperature display will show xxx if a temperature reading is outside the allowable range. Temperature 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 A until 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. • To return the temperature sensor to its factory default calibration (indicated by OFF on the display), press D and B at the same time. 4. To exit the calibration screen, press A. Current temperature calibration value To specify the temperature display unit 1. Enter the Timekeeping Mode. 2. Hold down A until the city code starts to flash, which indicates the setting screen. 3. Press C nine times until the temperature display unit flashes on the display. • See step 3 under “To set the time and date” for information about how to scroll through setting screens. 4. Use D to switch between Celsius (°C) and Fahrenheit (°F). 5.

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 Mode, place it on a flat surface, or if you are wearing the watch, make sure that your wrist is horizontal (in relation to the horizon). 2. Point the 12 o’clock position of the watch in the direction you want to measure. 3. Press D to 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 display. • A pointer on the display indicates magnetic north. • After the first reading is obtained, the watch continues to take direction readings automatically each second, for up to 10 seconds. • To perform direction readings for another 10 seconds, press D again. Direction indicator North pointer 12 o’clock position Angle value (in degrees) NW 0° WNW W W S W SW S S W S S S E SE E S E E E N E NE N N E N NNW 90° 180° 270° • The appearing on the display after a direction reading is complete indicates that bearing 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. • See “Digital Compass Precautions” for other important information about taking direction readings. Direction Meaning Direction Meaning Direction Meaning Direction Meaning NNE ESE SSW WNW NE SE SW NW North- northeast East- southeast South- southwest West- northwest Northeast Southeast Southwest Northwest East- northeast South- southeast West- southwest North- northwest ENE SSE WSW NNW North East South West N E S W 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°. To calibrate the bearing sensor Rotate the watch in accordance with the movement of the flashing indicator. One second ▲ One second 1. Remove the watch from your wrist, and position it so its back is parallel with the ground and the 12 o’clock position is pointed away from you. 2. In the Digital Compass/Thermometer Mode, hold down A until the indicator at the 12 o’clock position starts to flash. This is the calibration screen. 3. Press D. • The flashing indicator will move clockwise on the face of the watch with each passing second. 4. Each time the indicator moves, rotate the watch so the indicator remains pointed away from you. 5. After the flashing indicator completes two full trips around the display (and you rotate the watch twice), press C. D ▲ ▲ • This completes calibration and exits the calibration screen. The message will appear on the display for about one second, and then a direction reading operation will be performed automatically.
Operation Guide 3157 3 • If you want to cancel bearing sensor correction, press D in step 5 instead of C. This will return to the screen in step 2. From there you can press A to exit the calibration screen. • The indicator will go around the display up to four times, if you do not stop it by pressing C. After the fourth time, the watch will exit the calibration screen automatically. To perform magnetic declination correction 1. In the Digital Compass/Thermometer Mode, hold down A until the indicator at the 12 o’clock position starts to flash. This is the calibration screen. 2. Press C. • The magnetic declination angle and magnetic declination angle direction will flash on the display. 3. Use D (+) and B (–) to change the magnetic declination angle and magnetic declination angle direction settings. Magnetic declination angle value Magnetic declination angle direction • You can select a value within the range of 90° W to 90° E with these settings. • The following explains magnetic declination angle direction settings. 0 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 turn off (0 OFF) magnetic declination correction (which effectively makes the magnetic declination angle: 0°) 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 1° West. 4. When the setting is the way you want, press A to exit the setting screen. Using the Digital Compass While Mountain Climbing or Hiking This section describes three real-life situations where you could use the watch’s built- in digital compass. • To set a map and find 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. • To find the bearing to an objective To set a map and find your current location 1. With the watch on your wrist, position it so the face is horizontal. 2. In the Timekeeping Mode, press D 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. Current location N N North indicated on the map North indicated by north pointer To find the bearing to an objective 1. Take a compass reading and then 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 Mode, press D 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 relative to your current location, so the bearing to your objective is straight ahead of you. 12 o’clock position N N Current location Objective Questions & Answers Question: What causes incorrect direction readings? Answer: • Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel beam, overhead wires, etc., or an attempt to perform direction measurement on a train, boat, etc. Move away from large metal objects and try again. Note that digital compass operation cannot be performed inside a train, boat, etc. Question: What causes different direction readings to produce different results at the same location ? Answer: Magnetism generated by nearby high-tension wires is interfering with detection of terrestrial magnetism. Move away from the high-tension wires and try again. Question: Why am I having problems taking direction readings indoors ? Answer: A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism readings. Move away from the object causing the interference or take the direction reading outdoors. Indoor direction readings are particularly difficult inside ferro-concrete structures. Remember that you will not be able to take direction readings inside of trains, airplanes, etc. World Time World Time displays the current time in 48 cities (29 time zones) around the world. • If the current time shown for a city is wrong, check your Home City time settings and make the necessary changes. • All of the operations in this section are performed in the World Time Mode, which you enter by pressing C.
