3. Place the watch on a level surface, and position it so that its 12 o’clock position
points north (as measured with another compass).
4. Press

is shown on the display while calibration is being performed. When
calibration is successful, the display will show

Bearing Memory
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
1. Press
C
to start a digital compass measurement operation (page E-50).
•
If a bearing memory direction angle value is already displayed, it means that
the bearing memory screen is displayed. If this happens, press
A
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
A
to store the current direction angle reading in Bearing Memory.
•
The Bearing Memory direction angle flashes for about one second as it is
stored in Bearing Memory. After that, the Bearing Memory screen (which shows
the bearing memory direction angle) will appear, and a 20-second direction
reading operation will start.
•
While the Bearing Memory screen is displayed, you can press
C
to start a new
20-second direction reading operation, which displays the direction angle for
the direction that the 12 o’clock position of the watch is pointed. The direction
angle of the current readings will disappear from the display after the direction
reading operation is complete.
E-63
•
During the first 20 seconds after you display the Bearing Memory screen or
during the 20-second direction reading operation while the Bearing Memory
screen is on the display, the direction stored in memory is indicated by a
Bearing Memory pointer.
•
Pressing
A
while the Bearing Memory screen is displayed will clear the
direction angle currently in Bearing Memory and start a 20-second direction
reading operation.
Using the Digital Compass While Mountain Climbing or Hiking
This section provides three practical applications for using the watch’s built-in digital
compass.
•
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.
•

•
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
C
to take a compass reading.
•
The reading will appear on the display after about two seconds.
E-65
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 E-53).
•
This will position the map in accordance with your
current location.
4. Determine your location as you check the geographic
contours around you.

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-41 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-68
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-64 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-61) 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.
