Remove radio chassis from housing and fasten steering column mounting bracket to bottom of housing with machine screws that are furnished, or if steering column can not be used, use the bolts that are furnished, to fasten housing to bulkhead of car, drawing the three bolts through the three mounting holes in back of housing. In this cage, be gure to a110m housing to extend about 3 / 4 * to 1" away from bulkhead, by adjustment or a series of nuts furnished for this purpose. This will relieve any warping of housing and chassis, so as not to throw radio set out of balance.

Now pass driving control cable through grommeted hole in front cover or housing. With radio chassis still removed from housing, set dial scale on remote control at 0. Using a small wrench or pair of pliers, unscrew bushing headnut on variable condenser backplate about three-fourths of the way, and pass control wire through hole in bushing beadnut, and with dial scale still at 0, grasp the condenser pulley in one hand and revolve same until condenser plates are all the way open and will not turn further in that direction. Holding condenser in this position, loosen clamp screw at top of the pulley and run control wire under clamp until all the slack is taken out of the wire. Then tighten clamp screw down tight on wire. Put chassis back in housing and bolt down as before removing it from housing.

The following diagram shows the connections for speaker cable, and is supplied for service purposes only, as the speaker is already connected to the plug of the chassis.

When locating a position for the receiver, always bear in mind that you must allow sufficient room for mounting the speaker. the Franklin Auto Radio has been designed to be mounted on the steer 1ag column or dash board. You may mount the set either in the driver's compartment of the car, or in the motor compartment. Then locating the three mounting holes for radio, be sure that you locate them accurately. The reason for this is that if the holes are not perfectly in line with the bolts on chassis, you will badly warp the receiver can on mounting it to the dashboard.

After mounting the radio receiver, the next operation is to mount the speaker. We recommend that you mount the speaker as high as poss1ble behind the instrument panel, the reason for this being that when mounted in this position, the speaker receives full advantage of the resonance effect of this space behind the instrument panel. You can easily prove this for yourself, by turning on the radio receiver and placing the speaker in various positions in the car.

You will then note the advantage of placing the speaker according to our instructions. After mounting the radio receiver, drill a 3/8" hole directly below the receiver in buck board. This hole 1s to be used for allowing A and B battery wires to pass through into the motor compartment. Directions for connecting these wires will be found in the following sheets.

The tuning control should be clamped on to the steering column at a height equal to that of the top of shift lever, as this makes tuning A natural motion. In cases where the steering column is of a smaller diameter than that of the clamp, use the leather shims furnished with the tuning control.

When running the wires and tuning control cable from radio to control be sure that you do not kink them excessively, as this will make the tuning control work hard. Always be sure to securely tape the tuning control at about every six inches along its length to some solid part of the car. If you do not do this and the control is left free to swing, it will de-ture the radio.


The "A" battery connections of the Franklin Auto Radio have no polarity. By this we mean, neither negative or positive, but the heavy green wire with tracer must always be attached to the "hot" side of storage battery (the un-grounded side of storage battery) The sheath may be attached to any convenient ground connection, such as any bolt passing into the frame of the car or direct to the grounded terminal of the storage battery.

The heavy green wire with tracer may be attached either directly at the "hot" side of the storage battery or to the heavy cable running to the starter switch. Never, under any circumstances, attach this heavy green wire with yellow tracer to any of the ignition wires or light wires. Special warning is given against connecting this wire to the generator wire anywhere along its length. It is also convenient and advantageous to connect this wire to one side of the car ammeter, so that when the receiver is turned on, the battery load is indicated on the ammeter.


Included with each radio is a special container for the "B" batteries. This container is to be mounted through the floor boards of the car, wherever possible. In mounting this "B" battery box, be sure that you check underneath the floor boards to see that there are no brake rods, muttlers, storage batteries or other parts of the car located directly below the space in the floor boards. The proper method for locating the place for the "B" battery container is to hold it against the floor boards from underneath car, drilling four small holes up through the floor board at the four corners of the box. After doing this, you can out the hole from above and teal assured that you will not min into obstructions underneath the floor boards.

If it is a wooden floor board, you can very easily cut this with a key-hole sar. If, however, the floor boards are metal, no recommend cutting the hole with a cold chisel and a hammer, using a shearing action by holding the cold chisel as nearly parallel to the floor boards as possible. By using this method, you will find it very easy to cut these metal floors.

Whenever cutting through floor boards, be sure to do it in such a manner so as not to weaken floor boards of the car. In some cases, you will have to fasten braces underneath the floor boards at the edge of "B" battery can to strengthen the floor of car, due to the fact that sometimes the only location for the "B" battery can necessitates cutting through the whole width of one floor board.

When placing "B" batteries in "B" battery container, wedge card board or wooden shims beside the batteries to hold them securely from rattling. The proper method of connecting these batteries together 1a 111ustrated in the following diagram:
