To whom it may concern

In accordance with KDB 178919 DO1 and FCC rule part §2.1043: Changes in Certified

FCC ID: 2ALA3—CBUASR as detailed below:

The following non—radio parts of the device have been modified: Input overcurrent
protection added, internal DC/DC switched mode power supply has been removed and
output interfaces have been replaced with 4 ch PWM outputs.

The radio circuitry/layout, antenna, and settings remain unchanged from the original

As a result of the changes, the following test cases have been tested to verify —

        rule part 15.209 / 15.247)
    e   AC Conducted Emissions (FCC rule part 15.207)


Yours faithfully,
