Adjusting Delco Syncro-Tuning—
Turn the receiver on.
Tune-in a radio station which logs between 55 and 65 on the dial and gives the radio a signal BARELY AUDIBLE in the speaker WITH the VOLUME control FULL ON. A small snap button cap is located in the end of the receiver case beside the antenna lead connection. Remove the snap button cap by prying with a small screw driver.
By means of a small screw driver inserted in the hole which was covered by the small cap, adjust the Delco Syncro-Tuning condenser unit for maximum output in the speaker. Remaining on same station, readjust station selector for maximum volume and readjust the Delco Syncro-Tuning Condenser unit for maximum output. No further adjustment of this unit will be necessary as the receiver is now adjusted for best operation with your car antenna. Replace the snap button cap.
