The Computer Collar
®
Unit
The Computer Collar unit is a patented microprocessor-controlled device, powered by a patented Power Cap
®
unit.
Note: ONLY use the post tightening tool to
tighten the correction posts. Use of other tools
will void the warranty.
DO NOT secure the correction posts in the
Computer Collar unit with any kind of glue
or adhesive.
Fitting the Computer Collar Unit
To work properly, the correction posts on the Computer Collar unit
must touch your pet’s skin.
1. Position the collar strap high on your pet’s neck with the Computer
Collar unit under your pet’s lower 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 Computer Collar unit appropriately.
Adjust the collar strap so it is snug enough to slide one fi nger
between a correction post and your pet’s neck.
4. Adjust the fi t of the 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 Computer Collar
unit. The collar must be removed each night during the fi rst month
of training. This ensures proper fi t and avoids the possibility of skin
irritation.
6. After training is complete, remove your pet’s 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 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.
Changing the Power Cap
®
Unit
1. Use a small, thin coin to remove the Power Cap
®
unit from the
Computer Collar unit. Insert the coin in the slot on top of the
Power Cap unit and turn it counter-clockwise. Do not push down
while turning. The Power Cap unit will rotate up and out of the
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 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
fi rmly, turning it clockwise with your fi ngers.
