This bulletin supersedes Technical Bulletin Group 9, Book E, Number 8809, pages 273 and 274.

Models Affected: Vehicles with Reno II radios, Stuttgart radios and Alpine CD-2 compact disc players

Concern: Obtaining and entering security codes.

The purpose of this bulletin is to provide general information on Porsche radios and CD players requiring the use of security codes.

General Information: Built-in anti-theft circuitry will render the audio system of the radio/CD-2 unusable if the power supply is disconnected or voltage drops below 5 volts. When the radio/CD-2 is electrically reconnected, it will not operate until a security code assigned to the specific radio/CD-2 is correctly entered.

The security code is shown on the car radio identification card that is supplied to the customer with the radio/CD-2 owners' manual. This code must be obtained before the power supply is disconnected. If a security code cannot be obtained from a customer, contact the Porsche Cars N.A. Warranty or Service Technical Support Department by phone to obtain the security code. The following information is required:

- Dealer number and dealer contact name
- Customer name
- Vehicle identification number
- Radio/CD-2 serial number from radio/CD-2 cover plate (Figures 1-3)
