NOTE
Using Universal R-box and Universal Socket Module
The universal R-box and the universal socket module are the do-it-yourself kit for
installing a resistor you want or mounting a socket you want.
You need to prepare the hexlobe (torx type) screwdriver T-10 to remove the cover.
After installing a resistor or mounting a socket, reattach the cover. Do not use the universal
R-box and the universal socket module under the condition that the cover is removed.
