2.Use E(East) and B(West) to change the settings.
•The following explains magnetic declination angle direction settings.
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 select a value within the range of W 90° to E 90° with these settings.

Precautions about bidirectional calibration
•You can use any two opposing directions for bidirectional calibration. You must, however, make sure that they are 180 degrees opposite each other. Remember that if you perform the procedure incorrectly, you will get wrong bearing sensor readings.
•Do not move the watch while calibration of either direction is in progress.
•You should perform bidirectional calibration in an environment that is the same as that where you plan to be taking direction readings. If you plan to take direction readings in an open field, for example, calibrate in an open field.

To perform northerly calibration
Important!
If you want to perform both northerly and bidirectional calibration, perform bidirectional calibration first, and then perform northerly calibration. This is necessary because bidirectional calibration cancels any existing northerly calibration setting.

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 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 location
1.With the watch on your wrist, position it so the face is horizontal.
2.Press Cto 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. For details, see “Calibrating the Bearing Sensor” (page
•This will position the map in accordance with your current location.
4.Determine your location as you check the geographic contours around you.
