Bearing Memory
Screen
Bearing Memory lets you store a direction reading and display that reading as you take subsequent digital compass measurements. The Bearing Memory screen displays the direction angle for the stored direction, along with an indicator on the display that also indicates the stored direction.
When you take digital compass measurements while the Bearing Memory screen is on the display, the direction angle of the current digital compass measurement (as read from the 12 o'clock position of the watch) and the currently stored Bearing Memory direction information will both be displayed.
To store a direction angle reading in Bearing Memory1. Press C to start a digital compass measurement operation. |
• If a bearing memory direction angle value is already displayed, |
it means that the bearing memory screen is displayed. If this |
happens, press E to clear the value currently in Bearing Memory |
and exit the bearing memory screen. |
2. During the 20 seconds that digital compass measurement is in |
progress, press E to store the current direction angle reading in |
Bearing Memory. |

•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
To set a map and find your current location1.With the watch on your wrist, position it so the face is horizontal.
2.While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.
• The reading will appear on the display after about two seconds.

| • If the watch is configured to indicate magnetic north, align the |
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 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 the procedure under “To perform bidirectional calibration”.
Barometer/Thermometer
This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature.

1.While in the Timekeeping Mode or in any of the sensor modes, press B to enter the Barometer/Thermometer Mode.
•BARO will appear on the display, indicating that barometric pressure and temperature measurements are in progress. The measurement results will appear on the display after about five seconds.
•After you press B, the watch will take readings every five seconds for the first five minutes, and then every two minutes after that.
2.Press D to return to the Timekeeping Mode.
•The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about one hour after entering the Barometer/Thermometer Mode.

1. Set the map so its northerly indication is aligned with north as indicated |
by the watch, and determine your current location. |

Temperature
Barometric pressure
Display Units•Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg).
•The displayed barometric pressure value changes to - - - if a measured barometric pressure falls outside the range of 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg). The barometric pressure value will reappear as soon as the measured barometric pressure is within the allowable range.
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
You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured barometric pressure, and Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value. See “To specify temperature, barometric pressure, and altitude units”.

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 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.
