PATENTED BY MICHAEL AND BART BELLON

The Chameleon® Extender has been patented
(US Patent 8,783,212 B2 and EP pending) and
designed by Michael and Bart Bellon. By
affixing your ecollar brick to the Chameleon®
Extender, you will be able to benefit from the
Chameleon® collar design while being able to
use your existing brand (limited to Martin
System, D o g t ra, D o g Trace, E -Co ll ar
Technologies, Garmin, Sit Means Sit, and Sport
Dog brands).
With the Chameleon® Extender, you can have
one brick collar and have the utility of two
bricks. You can have more than one positive
and negative contact point. Additionally, with
the Chameleon® Extender, you can move your
contacts and change the number of contacts to
have optimal contact and best sensitivity for
your dog. You can move the contact points as
frequently as necessary to eliminate possibility
of necrosis. Additionally, you can use the
Chameleon® Feather Contacts which are
compatible with the Chameleon® Extenders
(and all Chameleon® collars) and give the best
contact with flexible comfort.
To affix the brick to the Chameleon® Extender,
you unscrew your contact points and then place
your brick on the Chameleon® Extender and
then screw your bolts (or your screws) back on
the brick. Whether you use bolts or screws
when attaching the brick is specific to each
brand. After tightening the screws/bolts well
with a special wrench (delivered in the package
with your Extender), then you cover the holes at
the inside of your Chameleon® Extender with
the two delivered plastic covers. The plastic
covers need only to be pushed on.
You can purchase the feathers as an option to
ensure optimal contact.

How to install my collar receiver on the CEMS® Extender
Incorporation of the Chameleon®!Charging Cable with your Martin
System charging system makes charging quick and easy.
Other brands aside from Martin System receivers can work on the
CEMS®, but the CEMS® is too small to support alternate charging
methods, so other brands will have to be removed from the CEMS®
for charging.

case, the micro) and
unscrew the contact
points.
