Extend the aerial wire as 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 positionwhich yields the best AM reception, or attach it to a wall or other surfaceas shown in figure.L ch speakerTuner/AmplifierR ch speakerAerial wireExternalAM loopFM75AM LOOPEXT.ANTSPEAKERS (6 MIN.)LRSPEAKERS(6 MIN )SUB WOOFER OUTRLVIDEO(AUD O)INLRSYSTEMCONNECTORAC DCDCDC4V12V5V30VEXT ANTFM75AM LOOPNote:To minimize noise, the speaker, mains and any other leads should notcome close to the indoor or external aerial lead and AM loop aerial. Do notplace the aerial leads close to the system.SpeakersWhen connecting the speakers, make sure that (+) and () polarities arematched properly. Otherwise, the sound may appear to be lacking in thebass range and in stability.Connect the speaker wire with the stripe to the red terminal (+) and theother wire to the black terminal ().Note:If desired, the speaker grilles can be removed.- 8 -LASER BEAM SAFETY PRECAUTIONNotes:-For Tuner/Amplifier: The rating label is located on the bottom of the unit.- The unit is not disconnected from the mains unless it is unplugged from the AC outlet.Pick-up that emits a laser beam is used in this CD player section.(CD CHANGER)(MD DECK) (XE only)CAUTION INVISIBLE LASER RADIATION WHEN OPEN ANDINTERLOCKS DEFEATED.
