Troubleshooting a G-13 payment terminal intermittently rejecting transactions. Focus: external causes, cable integrity, and ESD prevention.
Refer to the original purchase documentation or contact the vendor.
Contact certified technical support. Do not attempt to update the firmware without proper authorization.
Use a dry, lint-free cloth to clean the touchscreen and exterior surfaces. Avoid using liquids or abrasive cleaners.
Transaction failures can arise from voltage fluctuations, signal attenuation in communication cables, or electrostatic discharge (ESD) events. External electromagnetic interference (EMI) from nearby devices may also disrupt data transmission. The terminal's internal software relies on consistent data input for transaction authorization.
Safe Handling: Disconnect the power supply before inspecting cables. Avoid touching internal components. Do not use excessive force when connecting or disconnecting cables. Static electricity can damage electronic components; ground yourself before touching the terminal. This device contains sensitive electronics. Under no circumstances should the device be opened, as it will trigger anti-tamper mechanisms.
Regularly inspect cables for wear and tear. Implement cable strain relief to prevent damage to connectors. In dry environments, use anti-static mats and sprays to minimize ESD. Clean the touchscreen regularly with a dry, lint-free cloth. Ensure the terminal is plugged into a dedicated power outlet.
Try a different power outlet to rule out voltage fluctuations. A simple test is to use a different outlet on a different circuit. Ensure the power adapter is the correct voltage/amperage for the G-13. Consider using a power conditioner to filter out voltage spikes and noise.
