Wintec R-1060 Receiver questions

I have a few questions:

1 )Does this unit have a fuse or just a relay ?

if there is a fuse....where is it located ?

2) How to remove wood cover...there are many screws on the bottom ...which ones will remove cover?

3) I cannot find much information about this receiver.

Does anyone own this unit and provide me with  info:

4) Wintec is manufactured by _____?

It may have been made by Kyocera OR Luxman ??

Thoughts please 

Thank you
