•Pressing Awhile 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

•Whenever you suspect that the watch may have become magnetized, perform the procedure under “To perform bidirectional calibration” (page
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.).
Thermometer
This watch uses a temperature sensor to take temperature readings.
•The watch also takes direction readings in the Digital Compass/Thermometer Mode. For more information, see “Digital Compass” (page

To enter and exit the Digital Compass/Thermometer Mode
1.Press Cto enter the Digital Compass/Thermometer Mode.
•Press Cto take another reading.
2.Press Dto return to the mode you entered the Digital Compass/Thermometer Mode from.
•The watch will automatically return to the mode you entered the Digital Compass/Thermometer Mode from if you do not perform any operation for about one or two minutes.
Temperature
•Temperature is displayed in units of 0.1°C (or 0.2°F).
•The displayed temperature value changes to - - - °C (or °F) if a measured temperature falls outside the range of
Display Units
You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature value. See “To specify the temperature unit” (page
Temperature Sensor Calibration
The watch’s temperature sensor is calibrated at the factory and normally requires no further adjustment. If you notice serious errors in the temperature readings produced by the watch, you can calibrate the sensor to correct the errors.
4.Use E(+) and
•To return the currently flashing value to its initial factory default setting, press Eand Bat the same time. OFF will appear in place of the flashing temperature value for about one second, followed by the initial default value.
5.Press Ato return to the Digital Compass/Thermometer Mode screen, and then take direction and temperature readings.
Thermometer Precautions
•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.
2.Press Das many times as necessary until TEMP is displayed.
•See step 3 under “To change the current time and date settings manually” (page
3.Press Dto toggle the temperature unit between °C (Celsius) and °F (Fahrenheit).
4.After the setting is the way you want, press Ato exit the setting screen.
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.

Temperature Reading Precautions
When taking temperature readings, it is best to remove the watch from your wrist in order to eliminate the effects of body heat. Remove the watch from your wrist and allow it to hang freely from your bag or in another location where it is not exposed to direct sunlight.
