Your KRC-511 comes with a complete kit that includes a mount-
ing strap, bolts, washers, a front trim plate, accessory plate and
control knobs. Fig. 2 shows the proper installation procedure.
Look at the diagram and make sure that you have all the neces-
sary parts. Then, begin this procedure. |
Before installation, check the shaft span of the unit against the
openings on the dashboard of your car. If the openings do-not
coincide with the present shaft span of the unit, readjust it in the
following manner.
1. Loosen the hexagonal nuts on both shafts until the claws on
the fitting plates can be retracted from their present slots.
2. Move the claws of the fitting plates to other slots until the shaft
Span fits the dashboard openings. |
3. Tighten the nuts.

trated.
Then,
after
