I found the full page ad in Crappie magazine for the device you bought and figured out how the thing worked just by looking at the ad. From the ad: "Fish rely on color to signal the arrival of food in their environment, to seek a mate, for self defense or to find shelter."
All colors have their own specific frequency.

I stay with the bright green and yellow jigs with a Berkley crappie nibble and have excellent results in the Ross Barnett Reservoir in Mississippi.
Yikes! I went to the website and this thing costs $99.
There is a "Contact Us" link at their site. Maybe you can click it and send them an email requesting an owner's manual.
