RF channel: The radio frequency channel used between the handheld
unit and the collar unit for GPS communications and sending/receiving
Training functions. Highlight the box and press Left or Right key to cycle
between channels 1 through 6 .
NOTE - If there is interference from outside sources or if the signal is not
clear, the RF channel may need to be changed. This setting rarely
needs to be changed and should only be considered if there is outside
interference.
Satellite: Allows user to view available satellites and reception of
specific satellite signals. It also shows the
current Latitude, Longitude, and Altitude of the
handheld unit (
see fig. 1 to right ).
NOTE - H-value measures the GPS signal
strength that the handheld unit is receiving. The
lower the H-value, the stronger the signal. An
H-value of 2.0 or less is recommended. A
higher value may give less accurate GPS-
related information.
