20 MX800 SERIES INSTALLATION GUIDE

Calibrate

Touch Screen

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.

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.
