INSTALLATION

Antenna—

See Instructions in antenna package.

Chassis—

This receiver may be installed on any car with Positive or Negative ground without any changes of wiring.

When possible, locate the chassis on the driver's side of the dash, over the steering column, with the removable cover plate facing the floor. This position places the control shafts on the end of the case facing the center of the car.

Locate the position of the mounting holes by means of the template included in the package. Drill the holes, using a 3/8" drill, and scrape the paint from around the holes on the engine side of the dash to insure a good ground connection as there is no other ground connection for this receiver.

Make sure that all tubes and the vibrator are pushed well down in their sockets and that all the grid clips are properly in place on the top caps of their respective tubes.

If a six-volt storage battery is available, check the receiver for normal operation before permanently installing it on the car. The antenna lead and control unit may be temporarily connected for this test.

Insert the two receiver mounting studs in the back of the receiver case with the "burred" threads nearest the receiver to make sure that these studs do not enter the case far enough to cause damage to the receiver parts.

Install the receiver, using the drilling template as a spacer between the dash and the receiver case. Install the two shakeproof washers over the chassis mounting studs. Then tighten the mounting nuts to insure that the receiver case shall be thoroughly grounded to the dash.

Antenna Lead—

Attach the black antenna lead to the car antenna and plug the connector on the antenna lead into the receiver chassis as shown in the Installation Diagrams. Ground the pigtail of the antenna lead shield to a convenient body bolt. Keep antenna lead out of engine compartment to avoid possibility of ignition interference being picked up by the lead-in.

Speaker—

See Instructions in speaker package.

Remote Control Unit—

See Instructions in remote control package.

CONTROL UNIT ADJUSTMENT

The volume control and station selector shafts are AUTOMATICALLY adjusted as follows:

1. Insert control cables in their respective bushings on the case (volume control is upper bushing when receiver is installed in the car), until they seat themselves and then tighten the set screws.

2. Turn the station selector knob to the right (clockwise) until it stops—then turn the knob counter-clockwise until it stops. The dial is now logged.

3. Turn the volume control knob clockwise until the knob turns hard. The volume control is now on full.

Eliminating Motor Interference—

Connect the ammeter condenser to the spring clip at the end of the wire containing the fuse holder by means of the self-threading screw on the side of the spring clip. Ground the other terminal of the condenser at any convenient point.

Install the generator condenser on the generator side of the generator cut-out as shown in the Diagram of Connections....
