GREEN 5 flashes Battery strength is good
RED 4 flash Battery strength is weakening; replace Power Cap® unit
NO LIGHT Battery is dead; replace Power Cap® unit immediately
Should the red LED flash continuously while your pet is wearing the MaxDog ™
Computer Collar®, the Power Cap® unit strength is dangerously low; replace Power
Cap® unit immediately.
Replace your existing Power Cap® unit with one supplied via your Power Cap® unit
plan. If a fresh Power Cap® unit is not available, contact your Invisible Fence® Brand
Dealer for a replacement. Once a replacement Power Cap® unit is installed and the signal
field checked (
see page 6
for instructions on checking the signal field), put the MaxDog
™ Computer Collar® unit on your pet. The Invisible Fence® Brand pet containment
system is now ready.
Changing the Power Cap
®
Unit
1. Use a small, thin coin to remove the Power Cap® unit from the MaxDog ™ Computer
Collar® unit. Insert the coin in the slot on top of the Power Cap® unit and turn it 45
degrees counter-clockwise. Do not push down while turning. The Power Cap® unit will
rotate while the spring inside will push the Power Cap unit out of the MaxDog ™
Computer Collar® unit’s battery chamber.
2. Install a new Power Cap® unit using the following steps:
a. Line up the lugs on the bottom of the Power Cap® unit with the grooves in the sides
of the MaxDog ™ Computer Collar® unit’s battery chamber. Make sure the metal tabs
on the bottom of the Power Cap® unit are not bent.
b. Place the Power Cap® unit into the chamber while gently, but firmly, turning it
clockwise 45 degrees with your fingers.
c. Use a small, thin coin in the slot on top of the Power Cap® unit to turn it clockwise
until the slot on the top of the Power Cap® unit 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® unit should be changed every 3 months. Low temperatures,
the number of times the pet challenges the pet containment system boundary, and
improper collar fit can all reduce Power Cap® unit life.
Note: The use of any power source other than a Power Cap® unit will cause a receiver
to operate erratically or fail. Failure of the receiver due to the use of an unauthorized
power source could void the warranty. The use of unnecessary force may damage the
case and render the Power Cap® unit inoperable. NEVER open a Power Cap® unit,
dispose of it in fi re, recharge it, expose it to
Alignment Lug (one on each side)
heat
above 212°F (100°C), or expose its contents to water. Doing so can cause leakage or
explosion and may lead to personal injury.
