Boss alarm manual -is old and lost the manual-

Hello everyone !!

I have a boss alarm, it is ancient half, since I bought the vehicle (I came with it) and lost the manual ..
The issue is that I had it in silent mode and now for various reasons (change the battery and there was a problem with it) the alarm was bassinally barefoot and it is in modality of maximum security ... I do not remember how to make it again put it in silent or simpler mode ..
The only thing I remember is that you have to press 5 times the button that is under the steering wheel but I do it and nothing happens, I obviously cannot enter programming mode, I do not remember as it was ..

Does anyone know or have the manual to pass it to me?

Thanks for any help.
