INSTALLATION INSTRUCTIONS
FOR
1938 MODEL 8-50

RECEIVER MOUNTING
Mount this radio set on the bulkhead in the driver's compartment and, if possible, behind the steering column.
Place the cardboard drilling template in position on the dash and mark the mounting holes for the set. Most of the car manufacturers have provided punch marks and knock-out plugs on the bulkheads for the mounting of radios. The Motorola drilling template shows the location of some of the manufacturers' mounting holes, but these are to be used only as reference marks for the proper location of the receiver.

USE ONLY THE MOTOROLA STANDARD MOUNTING HOLES
Drill the two holes with a 1/4" drill. Clean the paint from around the mounting bolt holes on the side of the bulkhead.
Insert the 'T' mounting bolts through the bulkhead, install the special lockwashers and run the nuts loosely on the bolts on the motor compartment side of the bulkhead.
Raise the radio set into position in the driver's compartment, so the heads of the two mounting bolts slip into position in the mounting brackets on each side of the set.
Draw the mounting nuts down tight so the lockwashers dig into the metal surface of the bulkhead. IT IS HIGHLY IMPORTANT TO SECURE A GOOD GROUND AT EACH BOLT.

CONTROL HEAD MOUNTING
Install the control head in the instrument panel, following carefully the instructions found in the medallion or control head package.
Insert the square-tipped end of the volume control shaft in its receptacle (Fig. 1) through the side of the receiver housing. Push the housing bushing into place and turn a quarter turn to the right to lock it in position.
NOTE: In routing the flexible shafts from the radio set to the control head, be careful to avoid sharp bends, as this will cause the control mechanism to bind.
Insert dial light connector pin in its socket. (Fig. 1) (The dial lights in the Acouindicator and control head are connected in parallel, and terminate in a single pin.)
