The TCS-60DV detects rotation of both the supply and take-up side
reels using the PH701 (photo reflector). Because the PH701 is
mounted on the Main board, auto stop is activated and reel rotation
cannot be detected when the Main board is removed. To check the
operation of mechanism deck and voltage without the Main board,
follow the procedure as described below.
