Setting Security Code

OPERATION AND CONTROLS
The security input mode allows the user to enter codes to activate or deactivate the theft deterrent svstem and allows authorized service personnel to recall a specially encrypted factory code for use if the user's code is lost or forgotten.

To enter the security input mode from the VULNERABLE or SECURE states, the following conditions must be met:
1. Ignition On.
2. Radio power switch Off.
3. Press presets 5 and 6 for five seconds.

Once the radio is in the security input mode, one of two messages will be displayed depending on whether the theft deterrent system is activated. If the system is active (and the radio is not locked), "SEC" will be displayed. If the system is not active, - - - -"will be displayed. All controls except Power, AM/FM, preset combination 2+3, Seek up/down, and Tune up/down shall be inoperative.
Security input mode is automatically activated when the unit is in the LOCKED state.


Code Entry
The code entry method was selected to allow the user to enter a code consisting of four digits of the full range (0-9). This permits the user to select any familiar four digit number sequence for easy recall (such as birthday or phone number, etc.).

The following procedure is used to enter a four digit code during security input mode or LOCKED state:
1. Press < SEEK, SEEK >, < TUNE, or TUNE > to obtain "0000" display.
2. Press SEEK > to increment the first digit 0-9 with rollover.
3. Press < SEEK to increment the second digit 0-9 with rollover.
4. Press TUNE > to increment the third digit 0-9 with rollover.
5. Press < TUNE to increment the fourth digit 0-9 with rollover.
6. When the correct four-digit number appears in the display, press AM/FM to store the code.
