INSTALLATION AND OPERATING INSTRUCTIONS

MOUNTING
The chassis contains the complete radio, power supply and speaker. This unit may be mounted in any convenient location on the bulkhead of the car. If possible it should be mounted on the left side or close to the center. This makes for an easier installation. This installation is made by drilling only one 5/16 inch hole in the bulkhead. Care must be taken to see that the mounting bolts on this unit as well as all others, such as the antenna and generator condenser, form a good ground connection. This can be accomplished by scraping the paint from the spot under the mounting nut and washer.

Install flexible cables in the proper place (see figure 1). The other end of cables go to the controls 716 - T1 and 700 - V2. These are installed in the panel kit (see instructions furnished with panel kit). The "A" lead of the radio connects to power socket on control 700 - V2.

Antenna lead is plugged into the antenna socket (see figure 1).

After installation, tune in a weak station around 1400 K.C. and adjust antenna trimmer for maximum volume. DO NOT ADJUST OTHER TRIMMERS.

ELIMINATION OF INTERFERENCE
Remove the coil-to-distributor high-tension lead from the distributor. Cut the lead two inches from the end, and screw the distributor resistor onto the coil lead. Then screw the short length into the resistor, and plug the cable into the distributor cap.

One noise-filter condenser is furnished. Condenser must be connected to the output terminal of the generator (never to the field terminal). The generator-condenser bracket should be fastened to the generator housing, under the screw that holds the field. In some particularly stubborn cases of motor interference, one or more of the following procedures may be necessary:

A condenser can often be used to advantage on the electrically operated oil gauge or gas gauge. Connect the condenser lead to the terminal of the gauge, and bolt the condenser case securely to the frame or some other grounded part of the car.

Bonding the steering column to the fire wall with a short braid may also be effective. Clean the paint from the steering column at the fire wall where the column enters the motor compartment, and solder on a short piece of braid. Ground the end of the braid to the fire wall.

In some cases it may be necessary to ground the tubes and rods coming through the fire wall in order to reduce the interference. Clean them with emery cloth and spot-solder the braid. fastening the end under a convenient screw.

In some cases it may be necessary to connect an additional condenser to the ammeter or to the ignition switch.

It may be necessary to use a condenser on the voltage regulator. The condenser case should be mounted under one of the voltage-regulator mounting screws, or at some other convenient location, and the lead connected to the battery terminal of the voltage regulator.

interference from electric clocks can be eliminated by connecting a condenser to the ammeter terminal. The case of the condenser must be securely grounded.

If tire-static interference is noted in a particular installation, static collector springs should be obtained and installed in the front wheels of the car.
