To find the bearing to an objective
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” on
page E-48 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. 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.
E-52
To determine the direction angle to an objective on a map and head in that direction
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” on
page E-48 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 northerly direction indicated on the map
aligned with north as indicated 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. Press C to take a compass reading.
4. While direction angle readings are in progress, press
A to record the currently displayed direction in Bearing
Memory.
• The direction angle value and pointer stored in
Bearing Memory will remain on the display for about
20 seconds.
• See “Bearing Memory” (page E-45) for more
information.
5. Now you can advance while monitoring the Bearing
Memory pointer to ensure that it remains in the 12
o’clock position.
• To re-display the Bearing Memory direction angle
value and Bearing Memory pointer, press C.

• Pressing A while 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
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
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.
E-55
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.).
E-56
• Whenever you suspect that the watch may have become magnetized, perform the
procedure under “To perform bidirectional calibration” (page E-42).
E-57
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 E-33).
To enter and exit the Digital Compass/Thermometer
Mode
1. Press
C to enter the Digital Compass/Thermometer
Mode.
• Press C to take another reading.
2. Press D to 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 –10.0°C to 60.0°C (14.0°F to 140.0°F). The
temperature value will reappear as soon as the measured temperature is within the
allowable range.
Display Units
You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature
value. See “To specify temperature unit” (page E-61) for more information.
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.
E-59
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. Press C to enter the Digital Compass/Thermometer
Mode.
2. Hold down A until the current magnetic declination
correct values (page E-40) starts to flash on the display.
This is the setting screen.
3. Press D three times.
• TEMP will appear on the display along with the
current temperature calibration value.
