Sensitivity Control—
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.
Tone Control—
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.
To Turn Off The Receiver—
If the control head has a key knob in the center pull the knob out until it clicks into the off position and the receiver ceases to operate. If you wish to lock the receiver, pull the knob all the way out of the control unit and carry it with you.
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.
