CrC  or  CHKSUM FAIL  Message

"Cyclic Redundancy Code" (CrC) Checksum Error.

A "Cyclic Redundancy Code" (CrC) is a type of checksum algorithm that takes a string of data bytes and calculates from it a few bytes (the checksum) that depend on the entire file. The idea is that, if anything in the file changes, the checksum will change and Result in a CrC Error.

At Power-Up, the System has Failed the Program Checksum Test.  This indicates a Problem with the Firmware (Operation Program), or the System is Operating on Unreleased Firmware (Sample or Prototype System).  Try Turning the Power OFF and back ON again, or Continue for a Detailed Test Procedure.
