CAUTION - This device is not intended to be a tracking unit. Direction of
icons may be inaccurate by +/- 20 degrees. Readings can be affected
by electromagnetic interferences, obstructions, or loss of line of site.
NOTE - Be sure to hold the handheld unit parallel to the ground with the
screen facing towards the sky to properly view direction.
Actual North and Onscreen North are differing values. The moving Red
dot is Actual North while “N” at the top of the screen is Onscreen North.
Matching Actual North with Onscreen North will show proper direction of
units relative to Fence Center. To do this, hold the handheld unit parallel
to the ground and rotate the handheld unit (and your body) until the Red
Dot matches with “N” (
see fig. 1 below ).
The Paw Icon shows direction and distance of
the collar unit. The Person Icon shows direction
of handheld unit. Icons will show on the corner
edges of the compass screen unless it is within
10 yards of the Fence center, in which case it
will show in the center and read “Near.”
To get direction and distance of collar unit
relative to the handheld unit, stand at Fence
Center. The center of the screen is always
Fence Center, not the position of the handheld
unit.
