• Using the E-compass is recommended for static
occupations (lines/areas in vertex mode and points). The
GPS compass is recommended for trajectories (lines/areas
logged in automatic time or distance mode).
• E-compass readings stabilize after a few seconds. When
logging a point feature after a walking period, please hold
the receiver horizontally and wait a few seconds before
starting logging the feature.
• Tagging a picture file with bearing information: After
