Never attempt to disassemble, repair, or alter US320f under any circumstances. Failure to follow this instruction
may cause an electric shock or fire as well as malfunction of US320f.
Disconnect the power plug before opening US320f.
Make sure to power off US320f and disconnect the power plug from the power outlet before cleaning the unit or
attaching and detaching cables. Touching the inside of US320f with its power cord connected to a power source may

if water droplets are formed on a dusty plug, which may cause a fire.
