Use an insulated screwdriver or alignment tool such as RCA Stock No. 31031. Allow at least five minutes warm- up period before making adjustments. In the event that th

6、e receiver is to be used with an external an- tenna use one or two feet of wire (as an antenna) to ensure sharp peaking during the final adjustment procedure. For loop operation, the link should be strapped across terminals on back of set. In either case the procedure is as follows: 1. Make a list o

7、f the desired stations, arranged in order from low to high frequencies. 2. Turn the range selector to A band, and manually tune in the first station on the list. 3. After turning range selector to PB position, push in station button No. 1 (extreme left). Then adjust the No. 1 oscillator core (L-14)

8、to receive the station. 4. After oscillator core is set correctly, adjust C-8 for maximum output. Clockwise adjustment of cores and trimmers tunes the circuits to lower frequencies. 5. Adjust for each of the remaining stations in the saine manner. 6. Make a final careful adjustment of the oscillator

9、 cores and an- tenna trimmers. Owing to the relatively high r -f gain, it may be found that a given station can be tuned in at several different settings of the O ANT -ONO.
