The display works but none of the buttons or the fingerprint reader are responsive. I powered off and back on and it's still not functional.

If the buttons and fingerprint reader on your Grosvenor FP-GT4 are not responsive, try the following steps:

1. Check Power Supply – Ensure the device is receiving power through the 12V DC external PSU or battery backup module.
2. Reset the Terminal – Press the RESET switch to initiate a hardware reset and reboot the terminal.
3. Factory Reset – If the issue persists, press the RECOVERY switch to restore factory settings.
4. Verify Connections – Ensure the biometric reader connector and reader module are properly connected.
5. Check Software and Hardware Options – Menus and options vary depending on hardware and software versions. Refer to the additional instructions supplied with your terminal.
6. Contact Technical Support – If the issue continues, contact Grosvenor Technology support for further assistance.
