O 1850/1852/1853)
The Beeper horn is attached to the collar belt. It will 
emit a loud tone audible from up to 450 yards away. 
CAUTION
Do not cut the collar belt.
Doing so will damage the antenna and may result in
severely decreased receiver range.
Collar Indicator Light
When the Collar Receiver is turned on, the RED light 
will flash steadily once every two seconds to indicate 
that the unit is active. The RED light changes to a 
rapid flash (twice per second) when the battery is low 
and in need of charging. 
Electrodes
Electrodes should fit snugly on the dog’s neck to 
ensure good contact with the skin. For more 
information on the proper fit of the collar, see page 7. 
Battery Charging Receptacles
The battery charging receptacle is located on the side 
of the Transmitter, and on the side of the Collar 
Receiver facing the dog’s neck. After charging, 
always close the jack with the rubber plug to prevent 
foreign particles from getting inside the unit. 
Collar Belt with Embedded Receiver Antenna
The embedded collar antenna is woven into the collar 
belt, and runs the along the entire length of the belt.
