Our Warmest Thanks To...

Absolutely You!  We do what we do out of love and the hopes that people create and spread
their own liteness with the world.  You are a patron to this cause and to us…  Thank You!

Yoni.  While we’ve only met just a short time ago, we have aligned in deep ways and work in
harmony - keeping each other lite.  Meowww!

Hannes Pasqualini.  A gifted artist with a very positive and thought-provoking style that is
more than welcome here.

Installation

Install the power cable to your power distribution with the correct polarity.  Also ensure the
connector on the non-Rabid Elephant side is not shifted/offset incorrectly.

-12V is the side of the

connector with the RED STRIPE!

The red side of the cable go to the ‘STRIPE’ mark of the power

header.

NOTE: We have an

Appendix

located at the end of the manual which includes a

Quick Terminology

section

defining terms used throughout the document.
