I bought the car used. And if I don't know the code.....?
According to my OM.. maybe "LOC" flashes red?
Theft-Deterrent Feature
THEFTLOCK® is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is interrupted.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and
the radio is not protected by the feature. If THEFTLOCK
is activated, your radio will not operate if stolen.
When THEFTLOCK is activated, LOC will appear on the
radio display to indicate a locked condition anytime
battery power has been interrupted. If your battery loses
power for any reason, you must unlock the radio with
the secret code before it will operate.

It appears you'll need to contact a dealer. Maybe see if the original owner copied it to your OM. My radio had a sticker on it with the code, so I peeled it off and put it in there. Or maybe the code was never set?
Unlocking the Theft-Deterrent Feature
After a Power Loss
Enter your secret code as follows; pause no more than
15 seconds between steps:
1. Turn the ignition on. LOC will appear on the
display.
2. Press MN and 000 will appear on the display.
3. Press MN again to make the last two digits agree
with your code.
4. Press HR to make the first one or two digits agree
with your code.
5. Press AM FM after you have confirmed that the
code matches the secret code you have written
down. The display will show SEC, indicating
the radio is now operable and secure.
If you enter the wrong code eight times, INOP will
appear on the display. You will have to wait an hour
with the ignition on before you can try again. When you
try again, you will only have three chances to enter
the correct code before INOP appears.
If you lose or forget your code, contact your dealer.

I misplaced my original code as well and thought I would need to go to the dealer to have it reset, however Corvette Forum came to the rescue. See thread below:
