5. Operating Instructions
The module's settings are adjusted using the 'Start' and 'Stop' buttons. The 'Start' button functions as an 'Up' adjustment, and the 'Stop' button functions as a 'Down' adjustment during setting.
-
Set Starting Voltage:
In the normal voltage display state, press the 'Start' button once to display the current start charging voltage. To change this value, long press the 'Start' button for 3 seconds until the digital tube flashes. Then, use the 'Start' button (Up) or 'Stop' button (Down) to set your desired starting voltage value.
-
Set Stop Voltage:
In the normal voltage display state, press the 'Stop' button once to display the current stopping voltage. To change this value, long press the 'Stop' button for 3 seconds until the digital tube flashes. Then, use the 'Start' button (Up) or 'Stop' button (Down) to set your desired stopping charge voltage value.
-
Factory Reset:
While the module is powered on, simultaneously press both the 'Start' and 'Stop' buttons. The digital tube will display '888', indicating that the factory default settings have been restored.
