Changing Customer's Code

To change the customer's code, the radio must be unlocked and no customer's code can be currently stored in the radio. The radio will display "1:00" when unlocked. To determine whether or not there is a customer's code stored, press and hold pushbuttons "1" and "4" until the display changes. If "SEC" is displayed, there is a customer's code stored. If "- - -" is displayed, there is no code stored.
