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. 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 and it will have to be removed. Refer to "Removing customer's Code". If "- - -" is displayed, there is no code stored and a new code can be added.
