To Add Owner's Code

Important: If SEC displays, the theft-deterrent is already activated. This means the old code must be removed before entering a new code.
- Turn the radio OFF. Press and hold push button numbers 1 and 4 for about 6 seconds until the display changes to "- - -".
- Press HR to set the first two digits (0-19) of the code.
- Press MN to set the next two digits (0-99) of the code.
Important: If"- - -" displays after pressing AM/FM, the owners code has not been entered.
- Press the AM/FM button to enter the code.
- When REP then 000 are displayed, repeat steps 2 through 4 . This confirms the owners code and activates the theft-deterrent. SEC appears on the display indicating that the theft-deterrent is active, then the time of day appears on the display.
Anytime battery power is cycled and ignition is applied the LOC appears on the display. The system locks. To unlock the system use the owners code or the factory backup code. Refer to Radio Theft-Deterrent Unlocking After Power Loss.
