How to use Optical in function of RS201

I want to use my Oppo 83SE as my cd transport and connect with rs 201 with optical cable. But I do not know which mode to select in RS201 to make optical in function. Please help me

Hello,

If you hope to use Oppo 83SE as a music source
→ Connect Oppo 83SE (Optical Out) → RS201(Optical IN)
→ Go to ‘IN/OUT Setting’ in RS201
→ Activate ‘OPT IN’, then RS201 will receive digital signals via OPT IN.
