Safety precautions
Placement
Set the unit up on an even surface away from direct sunlight, high
temperatures, high humidity, and excessive vibration. These conditions
can damage the cabinet and other components, thereby shortening
the unit’s service life.
Do not place heavy items on the unit.
Voltage
Do not use high voltage power sources. This can overload the unit
and cause a fire.
Do not use a DC power source. Check the source carefully when
setting the unit up on a ship or other place where DC is used.
Power cord protection
Ensure the AC power cord is connected correctly and not damaged.
Poor connection and lead damage can cause fire or electric shock.
Do not pull, bend, or place heavy items on the lead.
Grasp the plug firmly when unplugging the lead. Pulling the AC
power cord can cause electric shock.
Do not handle the plug with wet hands. This can cause electric
shock.
Foreign matter
Do not let metal objects fall inside the unit. This can cause electric
shock or malfunction.
Do not let liquids get into the unit. This can cause electric shock or
malfunction. If this occurs, immediately disconnect the unit from the
power supply and contact your dealer.
Do not spray insecticides onto or into the unit. They contain
flammable gases which can ignite if sprayed into the unit.
Service
Do not attempt to repair this unit by yourself. If sound is interrupted,
indicators fail to light, smoke appears, or any other problem that is not
covered in these instructions occurs, disconnect the AC power cord
and contact your dealer or an authorized service center. Electric shock
or damage to the unit can occur if the unit is repaired, disassembled
or reconstructed by unqualified persons.
Extend operating life by disconnecting the unit from the power
source if it is not to be used for a long time.
Maintenance
To clean this unit, wipe with a soft, dry cloth.
•
Never use alcohol, paint thinner or benzine to clean this unit.

Before using chemically treated cloth, read the instructions that
came with the cloth carefully.
