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.
•Make sure that you 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.

Using the Digital Compass While Mountain Climbing or Hiking
This section provides three practical applications for using the watch’s
•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.

ERR disappears after about one second, try performing the calibration |
again. If ERR keeps appearing, contact your original dealer or nearest |
authorized CASIO distributor to have the watch checked. |

•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.

Screen
Bearing Memory lets you store a direction reading and display that reading as you take subsequent readings.
The Bearing Memory screen displays the direction angle for the stored direction, along with an indicator in the ring around the display that also indicates the stored direction. When you take compass readings while the Bearing Memory screen is on the display, the direction angle for your current bearing (as read from the 12 o’clock position of the watch) is also shown.
To store a compass reading in Bearing Memory
