About the e-mail below.
Now we have been AVR-X520BT, only a single item. You need to send us sample models AVR-X2200W,AVR-X4200W.
When should we get the sample for testing? Please send me if they're available.
So could you please support me any related doc.(catalog, CB Test, ISO 9001 certificate etc...)? We need to prepare for permission approval process by next step.
