Safety Precautions; Step - Panasonic SC-HT540 Operating Instructions Manual

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
places 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.
