AC -DC Operation.- This receiver will operate on 105 to 125 volta, AC 50 or 80 cycles, or DC. A power co

18、rd is housed in the bottom right hand corner looking inside the cabinet as shown in the illustration. Open the cabinet like a suit case, first pushing to one side the little pins under the handle ends to raise the clips. Then pull the power cord plug out of its socket in the top right hand corner as

19、 shown, and take out and unroll the power cord. A slot in the bottom allows the closing of the cabinet with the power cord passing through. Close the cabinet with the cord extending and insert the plug into a convenient electrical outlet. When returning to battery operation, be sure to replace the p

20、ower plug in its socket inside the case with the cord rolled up. NOTE. If reception is not obtained on DC, reverse plug in outlet receptacle. This may also reduce hum on AC operation. Using External Loop.- A loop antenna is housed inside the cabinet. Under normal condi- tions this will give satisfac

21、tory reception. If however the receiver is used in a location remote from broadcasting stations where signals are weak, or where interference is excessive, or in a shielded com- partment auch as an automobile, airplane or railroad traits, an RCA Magic Wave Magnifier Antenna with suction cup fastener

22、 may be purchased from your dealer. This antenna has a strap connector cord ending in a two -prong plug for attachment to the loop antenna frame. Open the case, plug the antenna cord into the socket (it will only go in.one way), bring the strap out at the slot in the case and attach the Antenna by m

23、eans of the suction cup to any convenient vertical surface. The RCA Magic Wave Magnifier may be attached inside the back case, when not in use, by means of three snap fasteners.
