Extend the aerial wire as

35、straight as possible and,while listening to the sound from the system, secure it in a position whichyields minimal distortion and noise.AM loop aerialAssemble the loop aerial as shown in figure. Unwind the aerial wires, thenconnect them to the AM LOOP terminals. Place the loop aerial in a positionwh
