PARTS & FUNCTIONS
Collar Indicator Light
When the Collar Receiver is turned on, the Red LED
light will flash steadily once every two seconds to
indicate that the unit is active. The Red LED light
changes to a rapid flash when the battery is in need of
charging. The Red LED light stays lit while plugged
into the charger.
Contacts
Contacts should fit snugly against the dog's neck to
ensure good contact with the skin. For more
information on the proper fit of the collar, see page 17.
Beeper Horn
(H

PLUS only)
The Beeper horn is attached to the collar belt. It will
emit a loud tone audible from up to 450 yards away.
Collar Belt with MAXX-Range ™ Antenna
The embedded collar antenna is woven into the collar
belt, and runs along the entire length of the belt.
CAUTION
If your collar belt is too long, we recommend looping the
excess collar belt back around through the buckle. We DO
NOT recommend cutting the collar belt. Cutting the collar
belt too much will drastically reduce the range of your collar
unit. However, the collar belt can be cut up to about 3
inches without affecting the range too much.
