Remove carrying handle and On-Off and Volume knob. 5. Remove 3 chassis mounting screws (indoing so, the cab inet back mou

3、nting bracket will also come out). 6. Remove chassis from cabinet (lift up right side of chassis first, to allow the tuning knob to clear its cutout on the cab inet). BATTERY DRAIN 10-14 ma (max) with no input signal NOTE: Due to the type of circuitry involved, there are two separate battery current

4、 paths, therefore, a DPST on-off switch is used. This necessitates two current measurements. A very simple, convenient method of measuring battery drain can be made without unsoldering any connections. The only items necessary are a low resistance DC milliam- meter and a jumper wire or two milliamme

5、ters. With the re ceiver turned off, place a milliammeter across the open terminals of one section of the switch and the jumper across the other section of the switch; the receiver is automatically turned on at the minimum volume level. The meter should read 10-14 ma; then interchange jumper wire an

6、d milliam- meter connections, the meter should read 10-14 ma. If two milliammeters are available, place one across each section of the switch, each meter should read 10-14 ma. s o 1 I O E 5 = i I ; F- S LJ O m O XT L_ -Sl y o c 1/1 , g 5o&J|. fe O O T N I9B646282 GANG / / . 1/2 TURNS GANG SET TO HIGH END (1620KC) ANT TRIM 1400 KC -Go ose TRIM 1620 KC ID IF 1ST IF OSC CORE 5 KC 455 KC 600 KC ALIGNMENT POINT LOCATIONS 90 ALTERNATE GANG 收音机爱 好者资料库 RadioFans.CN
