Troubleshooting radio interference issues with the PAX G10-S payment terminal. Safe handling, potential causes, and preventative measures for retail environments.
Use a Wi-Fi analyser app on a smartphone or tablet to measure signal strength in dBm.
Note any recent changes that might be causing electromagnetic interference.
Check the device's settings menu for firmware information.
The PAX G10-S uses specific radio frequencies for wireless communication (e.g., Wi-Fi, Bluetooth, cellular). Interference occurs when external radio signals overlap these frequencies, attenuating the signal-to-noise ratio. Electromagnetic Interference (EMI) from nearby devices can disrupt the G10-S's receiver sensitivity. Low voltage conditions can affect the radio module's performance. Baud rate mismatch can lead to faulty data transmission.
Intermittent or complete loss of wireless communication. Data transmission errors during transactions. Slow transaction processing times. Signal strength fluctuations. Unresponsive network connection.
Safe Handling: Always unplug the PAX G10-S from the power outlet before cleaning or moving it. Avoid using liquids or abrasive cleaners. Ensure the power outlet is properly grounded. Static electricity can damage electronic components; ground yourself before touching the device. Do not attempt to open or repair the device internally; this will void the warranty and may trigger tamper protection mechanisms.
Try using a USB extension cable to reposition the PAX G10-S slightly further away from the point-of-sale system or other potential interference sources. A small change in location can sometimes significantly improve signal strength. A clip-on ferrite choke on the power cable can help reduce EMI.
