My 94 EX has one of those cassette radios with an anti-theft device. When I let the battery run down, the power was disconnected to the radio. In an effort to get the radio to work again, I tried following the instructions in the owners manual. I turned the dial on, tried to punch in each of the numbers on the card provided by using the 1-6 station selector numbers on the radio. Nothing happened. Is there something else I should be doing? I thought I would ask before bringing the car to the dealership for service. Thanks Peter Neenan
