Troubleshooting
During normal, day-to-day operation of your MX800 Series terminal, it is possible 
for minor malfunctions to occur. Following are some examples of possible 
problems, and steps to resolve them. 
VeriFone follows stringent quality control standards in the manufacture of 
MX800 Series terminals. Each unit that leaves the factory has been rigorously 
tested to ensure quality and reliable operation. However, should you encounter a 
problem in operation, read this section for possible causes and solutions.
The troubleshooting guidelines provided in this section identify various problems 
and suggest the appropriate corrective action(s). If you have problems operating 
your MX800 Series terminal, please read through these troubleshooting 
examples. If the problem persists, or if it is not described below, contact your local 
VeriFone representative for assistance.

If the terminal display does not show correct or readable information, check all 
cable connections. If the problem persists, contact your local VeriFone 
representative for assistance.

Check whether the device connected to the serial port of the multiport cable 
of the MX800 Series terminal has power and is functioning correctly. If
