These modifications are only required in very rare circumstances. Composite Sync and Sync-on- Green are only required in RGB mode (never Component video/Y-Pr-Pb mode) and typically only with older, large front projectors. The rule of thumb is, if you are seeing a picture on your display, then you have the sync settings correct. VCR mode is only needed for the few displays that are unable to handle the erratic timing of a VCR.

To modify these internal settings, you will need to change a jumper that is only available after opening up your iScan Plus v2 unit. Read through these instructions first and if you feel that you are not comfortable with performing this type of operation, please ask your dealer to make the modification for you. They are generally happy to do so.

14)Turn the iScan Plus v2 unit so that the back of the unit is facing you. Remove the two screws on the back of the unit and set aside in a safe place – you will definitely need these

screws later!

15) Discharge yourself by touching some grounded, heavy metal object nearby.

16) Pull the back panel and EMI gasket off of the unit. The iScan Plus v2 printed circuit board is seated in the bottom slot in the chassis housing.

17) Notice the small metal clip straddling the board below the power input connector. You will need to remove this clip and put it aside for replacement later so pay careful attention to how it is mounted on the board. (See picture on next page).

18) Pull the board all of the way out of the housing.

19) There are three sets of jumpers on the board shown on the figure at right. Each of these locations should have three pins sticking straight up out of the board with a little plastic jumper straddling two of these pins.
