SilverCrest/Comag isn't listed in the 3 digit code sets I have, so a code search will be necessary. If that doesn't work it's unlikely there is a code.

N.B.
The instructions and codes are available here, though with the caveat of the latter being something of an educated guesstimate on my part (the original file, obtained from Chunghop* didn't include the codes). If you have an original copy of the instruction/codes I'd be very interested in borrowing/trading/buying** them from you.


*I would normally link to the Chunhop website, but it appears to be down...
