Tighten 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.

If 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).

Calibrating the Compass
NOTE: You must calibrate the electronic compass outdoors. Do
not stand near objects that influence magnetic fields, such as
cars, buildings, or overhead power lines.
The device has a 3-axis electronic compass. You should
calibrate the compass after moving long distances, experiencing
temperature changes, or changing the batteries.

Tips
• Turn on the dog collar device and allow it to acquire satellites
before you put the dog collar device on your dog.
This allows the dog collar device to acquire satellite signals
much faster.
• 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.
