Tips: No input voltage select switch, our upgraded voltage transformer can recognize the input voltage automatically and then provide the correct output voltage for your device. 1. Make sure all appliances are turned OFF. 2. Make sure your all appliances output rated power within the transformer rated power. 3. Please make sure your output appliances are plugged into correct input sockets. 4. Connect the electrical appliances to the transformer. 5. Choose the correct input voltage, press the powerON/OFF" switch toON" position and the LCD screen will show the "Pon IIIIII", then you can use it.
NOTES: 1) Avoid OverloadingThe maximum output doesn't exceed the transformer rated power. When connected with any appliances that built-in motor compressor, the starting power is generally 2-4 times of the appliance's listed power rating. Make sure that the total starting power capacity of all connected appliances does not exceed the listed maximum output power of the converter. For color TV, calculate it twice as its listed capacity. Make sure that the converter is of the same output voltage and frequency as the appliances' it connected. Make sure that the voltage of electrical source is the same as the input voltage of the converter. 2)FuseWhen the converter is over-current, the fuse button on the back of converter will pop up automatically to protect the device and converter, you need to reduce the loading by unplugging the appliances from the converter, and wait it for 3-5 minutes, then press the "FUSE" manually to reset it. Please note that the 500VA has no FUSE button. 3) Input voltageFor USA/Canada, input
voltage must be 100V-120VInput: 100V-120V, Output: 230VFor Europe/Africa, input voltage must be 220V-240V
