: The line has breached your safety threshholds. The device has isolated your load to protect it. Check if the indicator light shows a fault, and wait for the grid to drop back to its safe recovery range.
Connect the USB car charger to your device and plug it into your vehicle's cigarette lighter or 12V outlet. The device will power on automatically. This is also how you charge the internal battery for off-car use.
The configuration menu consists of numbered registers (A1 to A15). To enter the settings mode, for more than 3 seconds. Tap SET to cycle through parameters, and use the UP or DOWN arrow keys to modify values.

To enter setup, press the . Use the UP and DOWN buttons to change values. The device cycles through these key parameters: Description Default Value Adjustable Range A1 Power-on delay (Wait time before connecting load) 1s – 500s A2 Over-voltage protection threshold 230V – 300V (or OFF) A3 Over-voltage recovery voltage 225V – 295V A4 Over-voltage recovery delay time 1s – 500s A5 Over-voltage action time (Trip speed) 0.1s – 30s A6 Under-voltage protection threshold 140V – 210V (or OFF) A7 Under-voltage recovery voltage 145V – 215V A8 Under-voltage recovery delay time 1s – 500s A9 Under-voltage action time 0.1s – 30s A10 Over-current protection threshold 1A – 63A A11 Over-current recovery delay time 1s – 500s A12 Over-current action time 0.1s – 30s A13 Voltage calibration (Fine-tune display accuracy) Critical Installation Tips
