We are in process of designing Receiver. The receiver is too small in size, larger place is 2mm, as you see from below attached drawing. (See attached file: C-UBD58 outline drawing .JPG)(See attached file: P1010012.JPG)(See attached file: P1010014.JPG)(See attached file: P1010015.JPG) Laser etching on the metallic part could be subject to rubbing and could be hardly legible as well due to the bad contrast. Unless we remove the Logitech brand there is no other space on the plastic part. Due to described problem above, it has been decided to put FCC ID in the manual. I hope that it is acceptable to FCC, correct ? Please advise otherwise. Thank you very much for your help.
