Radio Anti-Theft Lock

Radio and cassette player are equipped with an electronic four-digit anti-theft lock. This four-digit code is programmed at manufacturing and cannot be changed. If the battery is disconnected for more than three minutes, if unit is removed or if otherwise cut off from power, the four-digit code must be entered with the quick-selection buttons as follows:

• Turn radio on, then, when display shows "Code In," enter four-digit code with quick-selection buttons. If code is correct, last-tuned radio frequency is shown on display. If wrong digit has been entered by mistake,...

The servo (booster) unit, Fig. , provides power assistance to the pedal effort applied. The servo obtains its power from vacuum created in the engine inlet manifold and provides assistance in a ratio of about 4 to 1. Should a vacuum failure occur, the two pushrods will act as a single rod, allowing brakes to work conventionally but with a much greater pedal effort.

When the brake pedal is depressed, pedal pressure assisted by power from the servo unit pushes the input rod into the master cylinder. The input rod pushes the primary plunger up the bore which closes the cutoff port to the fluid reservoir. This creates pressure ahead of the primary plunger. This pressure also acts on the secondary plunger, pushing it up the bore and closing the cutoff port from the secondary chamber. The pressure in both circuits increases and, because the plungers are the same size, pressure in each circuit is the same. Fluid pressure is directed to the brake syst...
