CD Player Anti-Theft Feature
Delco LOC I1
is a security feature for the compact disc
player. It can be used or ignored. If ignored, the system
plays normally. If it is used, your player won't be usable
if it is ever stolen, because it will go to LOC mode any
time battery power is removed. Until an unlock code is
entered, it will not turn on.
The instructions below tell you how to enter a secret
code into the system. If your vehicle loses battery power
for any reason,
you must unlock the system with the
secret code before the radio will turn on. Be sure to read
through the entire procedure and become familiar with
the appropriate buttons and knobs before starting.
1. Write down any six-digit number and keep it in a
safe place.
2. Turn the ignition to the ACC or RUN position.
3. Press the PWR button to turn the radio off.
4. Press the 1 and 4 pushbuttons together. Hold them
down until
"---"
shows on the display.
You are ready to enter your secret code. If you pause
more than 15 seconds between steps, you may have
to start the procedure over.
5.
Press SET and
"000"
will appear on the display.
6.
Press the
SEEK
button
to
make the first number
appear.
7. Rotate the
TUNE
knob right or left to make the last
two numbers agree with your code.
8. Press the lower (BAND) knob and "000" will appear
again.
Now you are ready to enter the last three digits of
your code by repeating steps 6 and 7 for the last
three digits
of
your code.
9. Press the lower (BAND) knob and "rEP" will appear
for five seconds and then
"000"
will appear
indicating that some steps are to be repeated.
10. Repeat steps 6 , 7 and 8.
11. Press the lower (BAND) knob. If the display shows
"SEC"
it indicates that the process was successful
and the radio is secure. If the display shows
"---,"
the steps were not successful and the process must be
repeated to secure.
