We were able to purchase a 2001 Sanyo DVD Home Theater System model (DWM1000M) with remote (RB-H520MT)but NO instructions. We've managed to get everything hooked up and it's a great system for it's age. Now we want to get rid of all the extra remotes and program from Sanyo's remote. BUT, we have no codes. I have been ALL DAY trying to locate such a simple request. You'd think 8 years was 200,000 thousand years. WHERE DO I FIND THIS INFORMATION? PLEASE HELP ME.
