If the program being received is from a powerful local station local interference may be practically eliminated by turning the sensitivity control to the LOCAL position. You then will get the best possible reproduction of that station's program.
The sensitivity control is located on the lower, left front corner of the receiver case and when turned to the LOCAL position it decreases the sensitivity of the receiver sufficiently to greatly reduce interference from street cars, electric signs, X-Ray machines, electrical machinery, power lines, etc. It will also eliminate interference from weak stations.
When the control is turned to the DISTANCE position the receiver is allowed to operate at maximum sensitivity.
The tone control is located on the lower, right front corner of the receiver case. This control is to be adjusted at the operator's will. However, most experienced operators prefer to set it for maximum treble response when the car is operated at high speeds.

If you are using the type of control unit which has a combination on-off switch and volume control knob turn the knob to the left until the receiver ceases to operate.
