Changing the Power Cap
®
Battery:
1. Use a small, thin coin to remove the Power Cap
®
battery
from the R21 v4.0 Titanium Computer Collar
®
receiver.
Insert the coin in the slot on top of the Power Cap
®
battery and turn it counter-clockwise.
Do not push
down while turning
. The Power Cap
®
battery will rotate
up
and
out
of the R21 v4.0 Titanium Computer Collar
®
receiver’s battery chamber.
2. Install a new Power Cap
®
battery using the following
steps:
a. Line up the lugs on each side of the bottom of
the Power Cap
®
battery with the grooves in the
sides of the R21 v4.0 Titanium Computer
Collar
®
receiver’s battery chamber. Make sure
the metal tabs on the bottom of the Power
Cap
®
battery are not bent.
b. Place the Power Cap
®
battery into the chamber
while gently, but firmly, turning it clockwise with
your fingers.
c. Use a small, thin coin in the slot on top of the
Power Cap
®
battery to turn it clockwise until the
slot on the top of the Power Cap
®
battery is
lined up with the two small raised tabs on the
bottom of the receiver.
Do not over tighten
by turning the slot past the tabs on the
receiver.
On average, the Power Cap
®
battery should be
changed every 3 months. Low temperatures, the
number of times the pet challenges the system
boundary, and improper collar fit can all reduce Power
Cap
®
battery life.
Warning: The use of any power source other than a Power Cap
®
battery will cause the receiver to operate erratically or fail. Failure of the receiver due to the
use of an unauthorized power source will result in denial of a warranty claim.
The use of unnecessary force may damage the case and render the Power Cap
®
battery inoperable.
NEVER open a Power Cap
®
battery, dispose of it in fire, recharge it, heat it above 212°F (100°C), or
expose its contents to water. Doing so can cause leakage or explosion and may lead to personal
injury.
