Do not "hot plug" the Reader! The Reader gets its power through the cable that
connects it to the Decoder. Do not remove or install this cable while the Decoder power
is on. Doing so may cause damage to the Reader and void the warranty.
Frame offset. Specific installation instructions for mounting the Reader to each type of
projector are available in the DFP-R3000 Installation Manual. Following these
instructions will ensure a minimum frame offset between the Reader's LEDs and the
picture gate. See Step 17 in Section 5, B-Chain Alignment. The frame offset must be
at least 32 frames ahead of the projector gate. The maximum frame offset
possible is 115 frames.
