3Tighten the strap so it is snug around the dog's neck.

NOTE: The collar should fit tightly and should not be able to rotate or slide on the dog's neck. The dog must be able to swallow food and water normally. You should observe your dog's behavior to verify that the collar is not too tight.

4If the strap is too long, cut off the excess, leaving at least 3 inches (7.62 cm) to spare.

Communication with the Collar

The handheld device and dog collar device 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 handheld device and your dog’s dog collar device produces the best communication signal. Obstructed radio waves result in a poor signal. To achieve the best line-of-sight conditions, you should move to the highest elevation point in your area (for example, on the top of a hill).

Poor

•Bring extra AA batteries for your handheld device.

•Use a fully charged dog collar device.

A fully charged dog collar device operates for approximately 26 hours when using five‑second interval reporting.

•Use line-of-sight radio communication (Communication with the Collar).

•From the dog tracking page, select MENU > Small Numbers to reduce the text size.

This allows you to view more dogs at one time on the dog tracking page.

This allows the dog collar device to acquire satellite signals much faster.
