Stuttgart Radio

Figure 3:

The 4-digit security code should be entered by the customer or servicing dealer to activate the builtin anti-theft circuitry on a new or replacement radio. The Stuttgart radio will operate even after the battery was disconnected or the radio was stolen if the security code was never entered by the customer or servicing dealer. This also applies to new cars. The factory does not enter the security code. In addition, a personal identification number can be entered by the customer. Refer to the instructions in the Stuttgart radio owner's manual.

The 4-digit security code must be entered by using preset switches 1 through 4 when display shows "code". After entering the correct code, depress the RIGHT SIDE of the search tuning rocker switch. If the code is entered correctly, the radio is ready to function again. If the code is entered incorrectly, the display shows for 10 seconds. After six unsuccessful attempts to enter the code, the waiting period is one hour, and after 20 incorrect attempts, the radio can only be decoded at the Blaupunkt service facility at customer expense.

To enter code 4393 for example, you must push
switch 1 - 4x
switch 2 - 3x
switch 3 - 9x
switch 4 - 3x

When the code is displayed, press fight part of the search tuning rocker switch.

Note: Each preset switch can be pressed repeatedly to reach the correct digit in the display. The code is not processed until the rocker switch is pressed.
