R21 v3 Series Receivers
The R21 v3 Computer
Collar receivers have an
added feature. The v3 will
beep once when a Power
Cap battery is installed.
The beep indicates that the
microprocessor in the
receiver is working and that the Power Cap battery has
enough voltage to power the receiver.
The three small circular indentations, equidis-
tantly spaced around the outer edge of the base that
supports the center battery contact in the receiver,
indicate that the receiver is an R21 v3 series
Computer Collar.

To wo rk pro p e rly, the correction posts on the
Computer Collar receiver must touch your pet’s
skin. Posts are ava i l able in three diffe rent sizes to
e n s u re a proper fit for eve ry pet: s h o rt , 1/2 inch
(12.7mm); long, 3/4 inch(19mm); and short - s p a c e d

your pet’s neck with the posts pointing up and the
top of the re c e iver pointing fo r wa rd, t owa rd yo u r
p e t ’s nose. Adjust the collar so it’s snug enough to
slide one fi n ger between a post and your pet’s
n e ck. Pe riodic adjustment of the Computer Collar
m ay be necessary as your pet’s coat , weight and
age ch a n ge.

battery installed. On average,
the battery should be changed every 3 to 4 months.
