Touch Panel (DC250TP) Installation
CRITICAL NOTE #1 : Pay attention to which screws go where. Missing screws (particularly the machine-thread screws) can cause poor grounding of some of the components and will cause failures.
CRITICAL NOTE #4: On the 76xx and 77xx models only, a touch problem has been reported to sometimes be caused by software issues. Reloading firmware for the UI is said to solve problems in those cases.
CALIBRATING THE TOUCH PANEL:
If the touch buttons seem to be “off” a-ways, you can recalibrate the touch panel like this: Power off the machine, then hold down the ‘1,0, & 3’ buttons together while powering back on. A calibration screen will show up. Use stylus to touch the 9 points labeled P1 through P9. The screen will change to a grid with intersecting lines. Touch the points where the lines cross in random order to see that the panel responds right.
Then turn the power off, wait a full 60 seconds and turn it back on.
