Random Key Presses when Replacing the Display Cover
When replacing the display cover with power applied to the 2920, you may see what appears
to be random key presses. This is due to the touch keys recalibrating when the cover is
replaced.
To prevent these random key presses, disconnect power from the unit prior to replacing the
display cover. When power is reapplied, the unit automatically re-calibrates to compensate for
the cover glass.
