Alpine CD-2
Figure 1:
When the CD player is switched on after the power supply was disconnected, the word "code" appears in the display. The 5-digit security code must be entered by using the preset switches 1 through 6. If the code is entered correctly the CD player is ready to function again. If the code is entered incorrectly in three consecutive tries, the display will show "off ". A waiting period of 24 hours is required before the CD player will accept another code entry. (Radio must be switched on with ignition key in radio position).
Important
When entering the security code, the display changes to "IN ". The code is processed as it is entered. Be sure to complete the 5-digit sequence even when mistakenly pushing a wrong switch. For example, the code number sequence is 54 321 and you mistakenly enter 53 instead of 54. Complete the entry anyway by pushing 321. The CD-2 player will not operate and "code" will be displayed. Re-enter the correct number sequence and the CD-2 player will become operative.
To enter code 54 321, for example, you must push switch
