POWER-CORD CAUTION
Handle the power cord by the plug. Do not pull out the 
plug by tugging the cord and never touch the power 
cord when your hands are wet as this could cause a 
short circuit or electric shock. Do not place the unit, a 
piece of furniture, etc., on the power cord, or pinch the 
cord. Never make a knot in the cord or tie it with other 
cords. The power cords should be routed such that they 
are not likely to be stepped on. A damaged power cord 
can cause a fire or give you an electrical shock. Check 
the power cord once in a while. When you find it 
damaged, ask your nearest PIONEER authorized 
service center or your dealer for a replacement.

If the AC plug of this unit does not match the AC 
outlet you want to use, the plug must be removed 
and appropriate one fitted. Replacement and 
mounting of an AC plug on the power supply cord of 
this unit should be performed only by qualified 
service personnel. If connected to an AC outlet, the 
cut-off plug can cause severe electrical shock. Make 
sure it is properly disposed of after removal.
The equipment should be disconnected by removing 
the mains plug from the wall socket when left unused 
for a long period of time (for example, when on 
vacation).

CAUTION
The
STANDBY/ON switch on this unit will not
completely shut off all power from the AC outlet. 
Since the power cord serves as the main disconnect 
device for the unit, you will need to unplug it from the 
AC outlet to shut down all power. Therefore, make 
sure the unit has been installed so that the power 
cord can be easily unplugged from the AC outlet in 
case of an accident. To avoid fire hazard, the power 
cord should also be unplugged from the AC outlet 
when left unused for a long period of time (for 
example, when on vacation).

VENTILATION CAUTION
When installing this unit, make sure to leave space 
around the unit for ventilation to improve heat radiation 
(at least 40 cm at top, 10 cm at rear, and 20 cm at each 
side).
WARNING
Slots and openings in the cabinet are provided for 
ventilation to ensure reliable operation of the product, 
and to protect it from overheating. To prevent fire 
hazard, the openings should never be blocked or 
covered with items (such as newspapers, table-cloths, 
curtains) or by operating the equipment on thick carpet 
or a bed.
