• Altitude: not exceeding 2 000 m.
• Relative humidity (maximum value at 40°C): 50 %.
• Frequency: reference value is in ±5 % (230 V~ 50 Hz).
• External magnetic field: not exceeding five times the earth’s magnetic field in any direction. It also
means the device should not be used in the proximity of a strong magnetic field.
• Sinusoidal wave distortion: not exceeding 5 %.
• After the item 1)-5), the device is ready for use. The device shall not be used if it fails to operate
correctly in accordance with the test sequence listed above. In this case please unplug the device
to outlet.
• Please make sure the device can work normally by conducting the above operation sequence at
first to protect against unexpected electric leakage hazard before use. Don’t misuse such as
dropping, immersion, etc.
• In case of electric leakage, the device will automatically shut off the power supply and prevent
electricity reaching human bodies.
• Seek advice from manufacturer or responsible vendor or a competent electrician for solution if the
device repeatedly trips with an appliance connected or if it fails to pass the test sequence listed
