Red Mark on the Collar Unit
The Red Mark indicates the location of
the Magnet Switch in the receiver. To
turn the receiver ON/OFF, touch and
hold the Red Mark with the Magnet Indicator (Red
Mark) on the side of the transmitter until the LED
light on the Collar unit starts to flash.
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.
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.
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.
