4.1. Routine Maintenance
•
Every day
: Use compressed air to blow dust off the Timecode Reader’s lens (on the
projector).
•
Every six months
–
or as needed
: Clean the DVD drives in the external unit using a DVD
cleaning disc.
•
After three months service – and every six months afterwards
: If your D600 Timecode
Reader Head does not have an RoHS sticker on it, check and recalibrate the Timecode Reader
Head’s voltage using TN-E550. (You can see TN-E550 on the free Datasat Digital
Entertainment Online Support site located on the Datasat Digital Entertainment website at
www.datasatdigital.com/Support/
.) Timecode Reader Heads with stickers indicating that they
are RoHS compliant do not require this adjustment.
•
Every two years:
Have a technician change the battery on the motherboard. Instructions for
the technician are listed in Appendix I,
Technical Maintenance
.
4.2. XD20 Playback Sound Check
After installing and setting up the unit—or doing a maintenance check—it is a good idea to play content
and stand in the theater while listening to the first few minutes of the movie. Check for the following:
•
The overall sound level is comfortable and balanced.
•
The DTS soundtrack quality is excellent and does not include extraneous noise.
•
The dialog is in sync with the picture being projected.
•
The surround speakers are heard at the correct level. (Please note that not all scenes will have
surround material.)
To adjust the overall sound level in the theater, adjust the main fader on the cinema processor.
If you are having soundtrack playback problems, first check the contents to be sure the
soundtrack that was loaded is the soundtrack for the film you are playing. Feel free to contact
Datasat Digital Entertainment Technical Support for assistance.
