Panasonic SC-PM22 Operating Instructions Manual page 5

Avoid placing the unit in areas of:
direct sunlight
high temperature
high humidity
excessive vibration
uneven surfaces (Place the unit on a flat level surface.)
Such conditions might damage the cabinet and/or other component
parts and thereby shorten the unit's service life.
To protect the unit against sound distortion and acoustical effects,
please place the unit at least 15 cm away from wall surfaces etc.
Never place heavy items on top of the unit or the AC mains lead.
It is very dangerous to use an AC power source of high voltage such
as for an air conditioner.
A fire might be caused by such a connection.
A DC power source can not be used.
Be sure to check the power source carefully, especially if on a ship
or other place where DC is used.
Avoid cuts, scratches or poor connection of the AC mains lead, as
this may result in fire or electric shock.
Excessive bending, pulling or slicing of the AC mains lead should
also be avoided.
Do not pull on the AC mains lead when you are disconnecting the
power, as this could cause an electric shock. Grasp the plug firmly
when you disconnect the AC mains lead.
Never touch the plug with wet hands or a serious electric shock
could result.
Ensure that no foreign objects, such as needles, coins,
screwdrivers etc., accidentally fall into the unit.
Otherwise, a serious electric shock or malfunction could occur.
Be extremely careful about spilling water or liquid on/into the unit, as
a fire or electric shock could occur.
(Disconnect the power plug and contact your dealer immediately if
this occurs.)
Avoid spraying insecticides onto the unit as they contain flammable
gases which can be ignited.
Insecticides, alcohol, paint thinner and similar chemicals should
never be used to clean the unit as they can cause flaking or
cloudiness to the cabinet finish.
Never attempt to repair, disassemble or reconstruct the unit if there
seems to be a problem.
A serious electric shock could result if you ignore this precautionary
measure.
If a problem occurs during operation (the sound is interrupted,
indicators fail to light up, smoke is detected, etc.) contact your
dealer or Authorized Service Center immediately.
Disconnect the AC mains lead if the unit will not be used for a long
time. Otherwise the operation life could be shortened.s
