[. . . ] Use a minus (-) screwdriver to set the voltage selector (on the rear panel) 10 the voltage setting lor Ihe area in which Ihe unit will be used. (11 Ihe power supply in your area is 117 V or 120 V, set 10 the "127 V" position. ) Note that Ihis unit will be seriously damaged il Ihis setling is not made correctly. (There is no voltage selector lor some countries; the correct voltage is al ready set. ) THIS TUNER/RECEIVER IS CAPABLE OF RECEIVING THE NEW AM STEREO BROADCASTS FROM THE AM BAND RADIO STATIONS. HOWEVER LlKE MANY TUNERS AND RECEIVERS CURRENTLY AVAILABLE ON THE MARKET IT WILL REPRODUCE THIS AM STEREO SIGNAL ONL Y IN AM MONO. [. . . ] Pay attent ion to the following points when attaching the anten na. · Do not attach it horizontally (to do so would impair recep tion). · Do not attach it close to metal surfaces (to do so would result in noise). · Do not attach it close to power cords, speaker wires, etc. · Do not attach it close to a tape deck (when the tape deck is being used, chirping or beeping sounds may be received). Connect the AM loop antenna to the AM 3ntenna terminals located on the rear panel of the unit. When attaching the antenna to a wal!, column or rack Find the height and direction of the anten na where reception is best and then fix it vertically to the wall, rack, etc. When attaching the antenna to the unit - - - , This type of installation may cause impaired recept ion or result in signa I noise. If possible, attach the antenna to the rack, a wall, or a column.
