No Response
From the Touch
Screen
The following are the corrective steps to be taken if the touch screen does not
respond or displays the incorrect response. (This procedure does not apply to the
MX830 terminal without touch screen.)
To perform a touch screen (panel) calibration, follow this procedure:
1 Press the recessed button near the top of the Magnetic Stripe Reader with a
straightened paper clip and hold while three LEDs in the MSR track turn on.
Release the button when the middle LED turns off. Keep hands away from
the display until the prompt appears for password entry.
2 Enter the password.
3 In System Mode, perform a manual touch screen compensation. Tap
CONFIGURE > right blue arrow > CALIBRATE > CALIBRATE. Follow the directions
on the display.
4 If the problem persists, contact your VeriFone representative for assistance.
NOTE
The MX800 Series terminal requires a touch screen calibration at the time of
installation. The terminal should be powered on and allowed to stabilize at normal
operating temperature; usually this takes no longer than 30 minutes, even if the
terminal was previously in a cooler or warmer location. The touch screen
calibration procedure (below) should then be performed.
