6. HANDLING PRECAUTIONS
The supplied power supply cord is designed for exclusive use with this unit. Never use it with other
equipment.
Use the unit in locations where the temperature is between 10 and +40 °C (no condensation should be
formed), and the humidity is less than 80%.
The unit is a precision audio component. To prevent failure, avoid locations where it may be exposed to
strong shocks or vibrations.
To clean, be sure to first disconnect the power supply plug from the AC outlet, then wipe with a dry cloth.
When extremely dirty, use a soft cloth dampened in neutral detergent. Never use benzene, thinner, alcohol
or chemically-treated towels, which may damage the unit's finish.
