Maintenance Required UAT/UT

What this means and what action is required?

If your Pinpad displays the error "Maintenance Required UAT/UT," it is experiencing a "tamper" error, indicating a hardware issue. This typically results from mishandling, such as dropping the Pinpad, attempting to clean the interior of the device, or trying to open the device, etc. These errors will require that a VASC Technician is contacted to replace the device.

Pinpad Screen Displaying “Welcome”, “Unable to log in to EPS”, or freezing:

The above error indicates that your Pinpad is not communicating with your POS/register. Follow the troubleshooting steps below to fix the issue.

If at any point during troubleshooting the Pinpad returns to normal (displaying site or brand name), you do not need to proceed further.

1

Register Log Out/In:

• Log out of the register/POS, then log back in and verify if the Pinpad is functioning normally.

2

Pinpad Reboot:

• Reboot the Pinpad.
• Once the Pinpad returns to Welcome screen, log out and log back in to the register/POS again.
• Check if the Pinpad is working normally.

3

Check the Pinpad cables (power + ethernet)

Look at the back of the Pinpad.

• Single Black cable: Follow it to the Multiport Adapter where both the power and ethernet cables are connected.
• Two cables: These are the power and ethernet cables connected directly to the Pinpad.

Reseat both connections. Make sure the ethernet clicks into place.
