How To Input Radio Code?

[flanker271]

I own a 92 LS400. Yesterday I had my alternator replaced. Now, the radio screen says "SEC". I know what the code is, but just need information on how to input my code. I lost my owner's manuel so I had make a post here.

From what I remember from the owner's manuel, you had to hold 2-3 buttons for 4-5 seconds then input the code. I can't remember which buttons they were. I tried many combinations but nothing happend. The screen just says "SEC". Can any LS400 members take a look at their owner's manuel and tell me the procedure to input the correct code?

Thank you.
