Pioneer VSX D736S

Recently, i bought an secondhand Pioneer VSX D736S. This AV amp cum receiver works prefectly. I have try to look for user manual for this model but not found. My location was in Malaysia. I was told that the same amp may have different model number in the different region.

Can someone enligthen me on the above different name model number or perhaps can tell me where i can find this manual.
