' Be sure to connectthe white plugs to the L (lcfi) and the red plugs to the R (right)jacks when making connections.
. Change the position of the FM indoor antenna until you get the best reception of your favorite FM stations.
. A ?5 Q outdoor FM antenna may be used to further improve the reception.
Disconnect the indoor amenna before replacing it with the ourdoor one.
' Place the AM loop altenna as far as possible from the receiver, TV set, spea]er cords and the AC input cord and set it to a
direction for the b€st reception.
. lf the receptionis poor with the AM loop antenna,an AM outdoor antennacan be used wirh the AM looD antenna.
. Make connectionsfirmly and conecdy. If not, it can causeloss of sound,noise or damageto the receivei.
' If the electricity fails or the AC input cord is lefi unpluggedfor about 2 weeks,the memorizedcontentswill be all clearcd.
