To reset the settings on the UTL GAMMA+ 12 Volt, follow these steps:

1. Enter calibration mode.
2. Change the required parameters by following the procedure (1.1, 1.2 & 1.3).
3. To exit calibration mode, press and hold the SMT switch for 10 seconds.
4. A beep will indicate that the system has exited calibration mode.

This will reset the settings based on the changes made.
