Before permanently installing the receiver in the car, remove the front

section of the can to make sure that all the tubes and the vibrator are

pushed well down into their sockets. Refit front section.

If a storage battery is available, having the same voltage as that of the
receiver, carry out a preliminary test for normal operation. The receiver
may be placed on the footboard of the car with the antenna lead and control
unit temporarily connected for this test.

MOUNTING- RECEIVER

The receiver is designed to be mounted on the fire wall of the car, and
and at a convenient height to allow the control cables to make a direct
connection or a gradual downward sweep with as wide a bend as possible.

The control cables should be tentatively mounted on the instrument panel

while the mounting position for the receiver is being determined, bearing in
mind the fittings on both sides of the fire wall, and making sure that no

rods or wires will touch the receiver case.

When the position of the receiver has been decided, mark the positions of
the receiver mount bolt holes on the fire wall of the car, using the drill
ing template supplied with the receiver. Drill two 5/16" dia. holes at the
positions indicated on the template,· and thoroughly clean off all paint and
grease from around the holes on the engine side of the fire wall to ensure
that nuts and washers make a good ground connection. Mount receiver in
position with the two mounting bolts provided. Care should be taken when
mounting on a formed fire wall not to overstrain the mounting to prevent
distorting the receiver can. (Refer diagram. Fig. 1)
