Radio Security Code

Radio will require anti-theft security code to be entered if battery is disconnected. Turn radio on. Radio should display "code". Using first 4 preset buttons, enter code number from customer supplied security card. Each preset button applies to code number digit. For example, No. 1 button sets the first digit of code number. Cycle button until desired number appears. Once code is entered, press TAPE or CD (as applicable) button. A "beep" will sound when correct code is entered. If code is incorrectly entered after 3 sucessive attempts, radio must be left on for one hour before it will accept code entry.
