Resetting Factory Sounds on N364

Somehow I overwrote Combi A with the sounds from Combi C on my brand new 364. I'm bummed!
Any ideas on resetting to the factory sounds? I've only had this machine for 3 days! Can't find any references in the literature. HELP!

Load Combi A bank (or all P/C/G for that matter) from Preload Disk that came with your N

WILL DO!
THANKS FOR THE INFO - DIDN'T KNOW IT WAS THAT EASY. HADN'T GOTTEN TO THAT DISK YET - DUH!
