Digital Compass

A built-in bearing sensor detects magnetic north and indicates one of 16
directions on the display. Direction readings are performed in the Digital
Compass Mode.
You can store a direction reading in Bearing Memory and display that reading
as you take subsequent readings.
• For more information about Bearing Memory, see "Bearing Memory".
• You can calibrate the bearing sensor if you suspect the direction reading is
incorrect.
• See "Using the Digital Compass While Mountain Climbing or Hiking" for
Day
some real-life examples of how to use this feature.

• While the watch is taking compass readings, it displays a direction angle, a
direction indicator, and four direction pointers, which change dynamically
when the watch is moved. The direction angle, direction indicator and
direction pointers all disappear from the display after the compass reading
operation is complete.
Note
• Note that taking a measurement
while the watch is not horizontal
(in relation to the horizon) can
result in large measurement error.
• The margin of error for the angle value and the direction indicator is ±11
degrees. If the indicated direction is northwest (NW) and 315 degrees, for
example, the actual direction can be anywhere from 304 to 326 degrees.
• Any ongoing direction measurement operation is paused temporarily while
the watch is performing an alert operation (daily alarm, Hourly Time Signal,
countdown timer alarm) or while illumination is turned on (by pressing L).
The measurement operation resumes for its remaining duration after the
operation that caused it to pause is finished.
• The following table shows the meanings of each of the direction
abbreviations that appear on the display.

the other sensor modes, press C to enter the
Digital Compass Mode.
• At this time, the watch will start a Digital
Compass operation. After about two
seconds, letters appear on the display to
indicate the direction that the 12 o'clock
position of the watch is pointing.
• The direction reading on the display is
updated each second for up to 20 seconds,
after which measurement stops
automatically.
2. Press D to return to the Timekeeping Mode.
1. While the watch is in the Digital Compass
Mode, place it on a flat surface, or if you are

north, south, east, and west.
• After the first reading is obtained, the watch
continues to take direction readings
automatically each second, for up to 20
seconds.
