Fitting the Collar on Your Dog

 CAUTION

Do not spray the device or collar with harsh chemicals including but not limited to flea or tick spray. Always 
ensure that any flea or tick spray that is applied to the dog is completely dry before placing the collar on the dog. 
Small amounts of harsh chemicals can damage the plastic components and collar strap.

Before you can put the collar on the dog, you must pair the navigator and dog collar device (

Adding a Dog to 

the Alpha

®

 Navigator Using Wireless Pairing, page 2

), and acquire satellite signals (

Acquiring Satellite Signals

page 2

).

Position the collar with the communication antenna pointing up, the GPS antenna facing up, and the LEDs 

facing forward.

Place the collar around the middle of the dog's neck.
Tighten the strap so it is snug around the dog's neck, and fasten the buckle.

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 the collar is 
not too tight.

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

Dog Tracking and Training

One navigator can track multiple dog collar devices and other navigators.

Dog Tracking

The navigator allows you to track your dog or multiple dogs, using the tracking compass or map. The map 
displays your location and your dog's location and tracks. The compass pointer indicates the direction of the 
dog's current location.
