The EUT moves forward, backward, left and right according to the command of the associate transmitter. Due to declaration from the manufacturer and our constructional checking, it is deemed that that the receiver of 9449, 9450, 9451, 9452,9453 and 9454 are same in circuit design and PCB layout, they only differ in the plastic cosmetic design. Hence, all testing was conducted on the representative model: 9453.
