About safety precautions

Warning – Serious injury or death is possible if all warnings are not followed.

  • Electrical shocks can occur if the unit is disassembled, improperly repaired or modified. This will also void the warranty.
  • For products without a cover, please do not touch due to the exposed high-voltage parts which may cause an electric shock.
  • Do not exceed the specified ambient temperature. Failure to do so may result in fire or an electric shock.
  • Do not insert or remove the power plug with wet hands. It may cause an electric shock..
  • Do not bend or pull by force, nor scratch the power cord or AC plug. Failure to do so may result in fire or an electric shock.

Caution ...

Follow these precautions to prevent personal injury or physical damage to the device.

  • Only use the correct input voltage, frequency, output voltage and current. Failure to do so may result in fire or electric shock.
  • Do not use in environments with moisture, oil, smoke, dusty places, or corrosive gases. Failure to do so may result in fire or electric shock.
  • If there is no output, or other abnormalities are recognized during use, please stop using it immediately and contact our sales office. If the product is an AC adapter, unplug the power plug.
  • Do not cover or wrap the AC adapter or charger with cloths, or bedding, etc. It will hinder heat dissipation and may cause overheating or fire.
