indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Important Precautions
• Invisible Fence®Brand pet containment systems have contained over two million pets. However, there are some
precautions you should take.
• Read and retain manuals: Read the entire Owner’s Manual before using your new Invisible Fence® Brand pet
containment system.
• Adhere to all warnings and cautions contained in any Invisible Fence® Brand manual.
used without the safety alert symbol, indicates a hazardous situation which, if not avoided, could
result in harm to your pet.
is used to address safe use practices not related to personal injury.
• Never open a Power Cap®Battery, dispose of it in a fire, recharge it, expose it to heat above 212º F (100º C), or expose
its contents to water. Doing so can cause leakage or explosion and may lead to personal injury.
• Not every pet can be trained to avoid the established boundary. Sometimes even a properly trained pet may cross the
boundary. Therefore, Invisible Fence, Inc., as well as Invisible Fence®Distributors and Dealers, cannot guarantee the
system will, in all cases, keep a customer’s pet within the established boundary. Accordingly, if a customer has reason
to believe that their pet may pose a danger to others, or harm itself, the customer should not rely solely upon the
Invisible Fence® Brand pet containment system to keep the pet from crossing the boundary.
• Do not install, connect, or remove your system during a lightning storm. If the storm is close enough for you to hear
thunder, it is close enough to create hazardous surges.
Read and follow the important instructions on how to avoid pressure necrosis. Proper fit of the Computer Collar®Unit
is important. A Computer Collar®Unit worn for too long or made too tight on the pet’s neck may cause skin damage.
Ranging from redness to pressure ulcers; this condition is commonly known as bedsores.
• Avoid leaving the Computer Collar Unit on the pet for more than 12 hours per day.
• When possible, reposition the Computer Collar Unit on the pet’s neck every 1 to 2 hours.
• Check the fit to prevent excessive pressure; follow the instructions in this manual.
• Never connect a leash to the Computer Collar Unit; it will cause excessive pressure on the contacts.
• When using a separate collar for a leash, don’t put pressure on the Computer Collar Unit.
• Wash the pet’s neck area and the contacts of the Computer Collar®Unit weekly with a damp cloth.
• Examine the contact area daily for signs of a rash or a sore.
• If a rash or sore is found, discontinue use of the Computer Collar Unit until the skin is healed.
• If the condition persists beyond 48 hours, see your veterinarian.
These steps will help keep your pet safe and comfortable. Millions of pets are comfortable while they wear stainless steel
contacts. Some pets are sensitive to contact pressure. You may find after some time that your pet is very tolerant of
the Computer Collar Unit. If so, you may relax some of these precautions. It is important to continue daily checks of the
contact area. If redness or sores are found, discontinue use until the skin has fully healed.
You may need to trim the hair in the area of the Correction Posts or switch to the longer Correction Posts to ensure
consistent contact. Never shave the pet’s neck; this may lead to a rash or infection.

To prevent an unintended correction:
• The Computer Collar®Unit should not be on your pet when the system is tested.
• Remove the Computer Collar Unit before making any changes to your system.
• Before placing the Computer Collar Unit on your pet, test the Boundary Area and Width after any change.
• The use of any power source other than a Power Cap Battery may cause a Computer Collar Unit to operate
erratically or fail. The use of unnecessary force may damage the case and render the Power Cap®Battery
inoperable.
• Train your pet according to the instructions in the Invisible Fence® Brand training manuals. Complete
all steps before allowing your pet to run free. Do not become overly confident if your pet has become
conditioned to the Invisible Fence Brand pet containment system sooner than expected.
• Your Invisible Fence Brand Dealer has professionally installed your pet containment system and ensured
it is working properly. You will want to perform periodic maintenance checks to make sure the system is
properly functioning for your pet’s safe containment.
• Check the Invisible Fence Brand transmitter periodically to make sure it is operating properly. To do this,
simply bring the Computer Collar Unit to the edge of the containment field to verify function.
• The transmitter has visual and audible signals to warn of a system malfunction. The transmitter should be
installed where such signals may be easily seen and heard. If the transmitter is installed by the customer
in an enclosed box, or in a place not readily accessible to the customer, the customer will not benefit from
the system’s warning functions, for which Invisible Fence, Inc., as well as Invisible Fence Distributors and
Dealers, assume no responsibility.
• Do not attempt to service any Invisible Fence Brand equipment. Refer all service to your authorized
Invisible Fence® Brand Dealer. Only your authorized Invisible Fence Brand Dealer should make adjustments
to your pet containment system.
• All Invisible Fence Brand pet containment systems are designed for domesticated animal use only. Never
attempt to use this product for any purpose not specifically described in this manual.
**Computer Collar Unit can be a choke hazard if you pet chews on the strap. **
• Use care when mowing, aerating, or trimming your lawn so as not to cut the loop wire.
• If you have any questions about any aspect of your Invisible Fence Brand pet containment system, call your
Invisible Fence Brand Dealer immediately.

How the System Works
The MicroLite®Plus Computer Collar®Unit is compatible with Boundary Plus® and 800 Series Transmitters
to contain your pet within areas you choose, or teach your pet to avoid specific areas such as flower beds,
gardens, or pools. The transmitter produces a signal that travels along the signal field wire and back to the
transmitter to produce an Invisible Boundary®barrier.
When your pet approaches the established boundary, the MicroLite Plus Computer Collar Unit generates a
tone and correction to remind your pet of the boundary. With training and praise, your pet will quickly learn
to avoid the established boundary.
Definition: A correction is a training term used to describe an action taken to discourage unwanted pet
behavior. The MicroLite Computer Collar Unit applies a correction when your pet crosses the boundary of an
Invisible Fence®Brand electronic pet containment system. Corrections are used in combination with rewards
to alter unwanted pet behavior.
Your Invisible Fence®Brand pet containment system will only work when:
a. The transformer is connected to the transmitter and to a functional standard electric outlet, via an approved
Lightning Protection Device. All Invisible Fence Brand pet containment systems must be grounded per the
National Electric Code to be protected against lightning (North American customers only).
b. The transmitter is on, connected to the signal field wire, and producing a signal along the entire length
of the wire.
c. The signal field wire is intact, continuous, and the transmitter’s Status Indicator light is blinking green.
d. The MicroLite Computer Collar Unit is correctly fitted and worn by your pet. The MicroLite Computer
Collar Unit must be adjusted so that both of the correction posts touch your pet’s skin.
e. The Power Cap®Battery in the MicroLite Computer Collar Unit is good and correctly installed. See page
6 and 7 for proper Power Cap®Battery operation.
About Thunder and Electrical Storms:
Even though your Invisible Fence®Brand pet containment system is equipped with a Lightning Protection
Device (North American customers only), it is still possible that it may be damaged during a thunderstorm,
or when an electrical storm is in the area. After a storm has ended, check the signal field width. See page 8
for periodic maintenance checks.

MicroLite® Plus Computer Collar® Unit
The MicroLite®Plus Computer Collar®Unit is a patented microprocessor-controlled device, powered by a
patented Power Cap®Battery.
ONLY use the post tightening
tool to tighten the stainless
steel correction posts. DO NOT
secure the correction posts in the
MicroLite®Computer Collar®Unit
with any kind of glue or adhesive.
Fitting the MicroLite®Plus Computer
Collar®Unit
To work properly, the correction posts on the
MicroLite Plus Computer Collar Unit must touch your
pet’s skin.
1. Position the collar strap high on your pet’s neck with the
MicroLite Plus Computer Collar Unit under your pet’s jaw.
2. To avoid having a collar that is too tight on a thick-
haired pet, thin some hair away in order to allow the
correction posts to make contact with the skin. Do not
shave the pet’s neck.
3. Tighten the collar strap of the MicroLite Plus Computer
Collar Unit appropriately. Adjust the collar strap so
it is snug enough to slide only one finger between a
correction post and your pet’s skin.
4. Adjust the fit of the MicroLite Plus Computer Collar Unit
as necessary as your pet’s coat, weight, and age change.
Your pet’s coat may change from season to season.
5. Allow your pet to become accustomed to its new
MicroLite Plus Computer Collar Unit. The collar must be
removed each night during the first month of training.
This ensures proper fit and avoids the possibility of
skin irritation.
6. After training is complete, remove your pet’s MicroLite
Plus Computer Collar Unit each night if possible. This will
help prevent irritation. However, if this it not possible,
please check the tightness of the collar each time you
feed your pet by removing the collar and then replacing
it back on your pet.
7. The MicroLite Plus Computer Collar Unit is waterproof. If
the nylon collar strap becomes wet, it is recommended
that it be removed from your pet and be allowed to air
dry before replacing the collar on your pet’s neck.
MicroLite Plus Computer Collar Unit Power Cap®Battery Status
The MicroLite Plus Computer Collar Unit monitors Power Cap Battery status. Each time you insert a Power
Cap Battery into your MicroLite Computer Collar Unit it performs a battery test. The LED status indicator will
show a flashing light, indicating power status.

Should the red LED flash continuously while your pet is wearing the MicroLite®Plus Computer Collar®Unit,
the Power Cap®Battery strength is dangerously low; replace Power Cap Battery immediately.
Replace your existing Power Cap®Battery with one supplied via your Power Cap®Battery plan. If a fresh
Power Cap®Battery is not available, contact your Invisible Fence®Brand Dealer for a replacement. Once a
replacement Power Cap®Battery is installed and the signal field checked (see page 8 for instructions on
checking the signal field), put the MicroLite®Plus Computer Collar®Unit on your pet. The Invisible Fence®
Brand pet containment system is now ready.
Changing the Power Cap Battery
Use a small, thin coin to remove the Power Cap Battery from the MicroLite
Computer Collar Unit. Insert the coin in the slot on top of the Power Cap
Battery and turn it 45 degrees counter-clockwise. Do not push down while
turning. The Power Cap Battery will rotate while the spring inside will push
the Power Cap®Battery out of the MicroLite®Computer Collar®Unit’s battery
chamber.
Install a new Power Cap Battery using the following steps:
a. Line up the lugs on the bottom of the Power Cap Battery with the grooves in
the sides of the MicroLite Computer Collar Unit’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 45 degrees with your fingers.
c. Use a small, thin coin in the slot on top of the Power CapBattery 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 Computer Collar Unit. Do not over-
tighten by turning the slot past the tabs.
On average, the Power Cap Battery 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 Battery life.
The use of any power source other than an Invisible Fence®Brand
Power Cap®Battery may cause a Computer Collar®Unit to operate erratically or
fail. 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, expose it to 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.
