– DO NOT touch or insert any foreign substance into the AC inverter. Be aware of the potential risk of electric shock or fire.
– Only use the AC inverter when the engine is running. Always disconnect the inverter when not in use.
– Using the AC inverter when the engine is off or leaving an electric device plugged in for a long time may drain the battery of the vehicle.
– DO NOT use any electric devices that consume more than 220 V (200 W) of power.
– Connecting an electrical device that generates excessive levels of electromagnetic noise to the AC inverter may cause abnormal sounds in the audio equipment or a malfunction in the vehicle's electronic devices.
– Connecting a faulty electronic device to the AC inverter may damage the inverter or the electric system of the vehicle.
– The LED indicator blinks if the AC inverter input voltage falls below 11.3 V. The inverter shuts off if the voltage falls below 10.7 V.Inspect the battery and recharging system.
