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.
Place it at least 15 cm away from wall surfaces to avoid distortion
and unwanted acoustical effects.
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.
AC mains lead protection
Ensure the AC mains lead 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
mains lead 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 mains lead 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.
