The following are the corrective steps to be taken if there is a gap in captured 
signature. (This procedure does not apply to the MX830 terminal without touch 
screen.)

Ensure that the stylus is pressed hard during signature capture.

If the problem persists, contact your local VeriFone representative for 
assistance.

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:

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.

Enter the password.

In System Mode, perform a manual touch screen compensation. Tap 

> right blue arrow > 

 > 

. Follow the directions 

on the display.

If the problem persists, contact your VeriFone representative for assistance.

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.
