pointer is shortened.
NOTE: When you are close to the dog,
the dog pointer may be inaccurate.

About Line-of-Sight Radio Communication
The Astro and DC 40 use radio signals to communicate. Objects in the path of
radio signals degrade the quality of the signals. Keeping an unobstructed line of
sight between your Astro and your dog’s DC 40 produces the best communication
signal. Obstructed radio waves result in a poor signal. To achieve the best line-ofsight conditions, move to the highest elevation point in your area (for example, on
the top of a hill).
