2. Turn the ignition ON (The radio displays LOC).

3. Press and hold presets buttons 2 & 3 or 1 & 4 for approximately 10 seconds.

4. The radio display changes from LOC to a three-digit number.

5. Write this number down.

6. You will then have fifteen seconds max before the next step must be performed.

7. Press the AM/FM button.

8. The radio display changes to another three-digit number.

9. Write this number to the right of the first one.

10. You now have a six or four-digit number, the first three digits are from STEP 3 and the last three digits are from STEP 5.

11. If you have a four digit number, it will show all four digits at the same time.

• Note:

• If you have activated the Theft-Deterrent feature of your radio and loose power, the radio goes into LOC (theftlock) mode.

• With the ignition on, you must use the MN and HR buttons to enter your personal code in order to unlock it.

• If you fail to enter the correct code eight (8) times, the radio goes into INOP mode.

• You have to wait an hour with the ignition on before the radio returns to LOC mode procedure:

• You may have two sets of the same number. Example- (233-233).

• Saturn and GEO Vehicles only require a four Digit Serial #

• The fourth digit will be half the size of the first three digits on Saturn and GEO Vehicles .
