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.
• When mounting the unit on an equipment rack
· Use the supplied rack-mounting bracket. (For the bracket attachment, refer to p. 103 "RACK MOUNTING
BRACKET ATTACHMENT.")
· Have the unit well-ventilated, and be sure to mount a 1U or more size perforated panel above and below
the unit to prevent the unit's internal temperature rise.
