* PJ HDC5420 Series weighs less than 3.0kg. 
-  The projector must be installed in a location that is 
sturdy enough to support the full weight of the projector 
and brackets. 
-  Use only the screws (three M4~16 screws) provided 
with the projector to attach the brackets to the projector.
■ Caution- Keep the machine away from humidity and dust. Other-
wise a fire or an electric shock might occur.
■ Caution- Do not place any objects on the machine. Doing so may 
cause the machine to topple over, possibly resulting in 
injury.
■ Caution- Do not place the machine on an unstable or tilted sur-
face. If it topples over, an injury might occur.
■ Caution- Do not place the machine or use it in an environment 
where it might get wet such as from snow, rain, or be-
ing near water. Doing so could result in fire or electric 
shock.
■ Caution- Do not put your face or hand near the exhaust vents. 
Doing so could result in burns or an accident due to hot 
air coming from the exhaust vents.
■ Caution- Do not use the machine on soft material such as paper or 
cloth that might get sucked into the intake vents. Doing 
so may cause heat buildup inside the machine, resulting 
in malfunction, burns, or fire.
■ Caution- Do not place the machine in a location where air flow 
is poor. Doing so may cause fire due to internal compo-
nents becoming overheated.
■ Caution- Do not place or store the machine in a location where 
direct sunlight or heat generation might occur. The heat 
may deform or wear out the exterior parts or negatively 
affect internal parts. Doing so could result in fire.

■ Caution- Do not place low heat resistant material near the exhaust 
vents. Hot air may come from the exhaust vents, result-
ing in damage to the machine or an accident.
■ Caution- Do not obstruct the machine’s vents. Doing so risks fire 
caused by overheated internal components.
■ Caution- Push the power plug all the way into the power outlet. 
Do not use a power outlet with a loose connection. Doing 
so may result in heat buildup. Plug the power cord in the 
correct direction into the base. If they are not plugged in 
correctly, it could result in smoke, fire, or electric shock.
■ Caution- If this machine is not going to be used for several days or 
longer at a time, disconnect its power cord from the wall 
outlet.
■ Caution- When disconnecting the power cord from the wall outlet, 
always pull the plug, not the cord. Pulling the cord can 
damage the power cord. Use of damaged power cords 
could result in fire or electric shock.
■ Caution- Be sure to disconnect the plug from the wall outlet and 
clean the prongs and the area around the prongs at least 
once a year. Allowing dust to build up on the plug con-
stitutes a fire hazard.
■ Caution- When performing maintenance on the machine, always 
disconnect the power cord from the wall outlet.
■ Caution- Do not place the power cord and connection cable in a 
way that might cause someone to trip and fall. The ma-
chine might fall over and cause an injury.
■ Caution- The machine may be very hot after it is turned off, espe-
cially the vents and the lower part of the unit where the 
lamp is located. Avoid touching these areas. Doing so 
may result in burns.
■ Caution- Do not place the machine on other equipment or vice 
versa. Doing so may cause heat buildup inside the ma-
chine or cause the other equipment to malfunction.
■ Caution- Do not increase the volume unless you are listening 
while increasing the volume. Also, lower the volume be-
fore turning off the power, because a loud sound may be 
emitted when the power is turned on and cause hearing 
damage.
■ Caution- Do not tilt the machine horizontally more than ±20 de-
grees. Doing so may cause the entrance of foreign objects 
in the housing of the machine which could result in fire 
or electric shock.
■ Caution- If the machine’s interior is not cleaned regularly, dust 
will accumulate. Fire and breakdown can result from 
heavy accumulation of dust inside this machine. Contact
