the ceiling mount kit, it is recommended to hold 
the mount kit and the projector using a metal bar 
or wire in addition to the mount kit fixing screws 
to prevent the projector from falling due to an 
earthquake or other cause. For that purpose, use 
a metal bar, wire, or screw that bears a load of at 
least 55 kgf. When using a metal wire, secure one 
end to a screw hole marked with an arrow on the 
rear terminal panel and the other end to the mount 
kit. (Don’t use screw holes without arrow marks.) In 
this case, make sure that the screw is inserted in 
the projector at least 5 mm. The length of the screw 
should be 20 mm or shorter. Also make sure that 
no electrical current is flowing in the mount kit due 
to current leakage or other cause. 
Rear projection
Ask a specialist for installation. For details, consult 
your dealer.
•	 For	rear	projection,	set	Image	Reverse	in	the	
Installation menu to Mirror. See page 27.
Caution:
•	 Placing	the	projector	directly	on	a	carpet	impairs	
ventilation by the fans, causing damage or failure. 
Put a hard board under the projector to facilitate 
ventilation.
•	 Place	the	projector	at	least	50	cm	(or	20	inch)	away	
from the wall to prevent the intake vents and the 
exhaust vents that emit hot air from being blocked.
•	 Do	not	use	the	projector	in	the	following	locations	
and manners, which may cause fire or electric 
shock.
•	 In	a	dusty	or	humid	place.
•	 In	a	sideways	or	upside-down	position.
•	 Near	a	heater.
•	 In	an	oily,	smoky,	or	damp	place	such	as	a	
kitchen.
•	 In	direct	sunlight.
•	 Where	the	temperature	rises	high,	such	as	in	a	
closed car.
•	 Where	the	temperature	is	lower	than	+41°F	(or	
+5°C)	or	higher	than	+95°F	(or	+35°C	).
•	 Keep	foliage	plants	and	pets	away	from	the	
projector. The temperature around the exhaust 
vents and that of the cabinet on the top of the 
exhaust vents become high. Take special care for 
small children.
Important:
•	 Do	not	apply	force	to	the	lens,	because	the	lens	
may be damaged.
•	 Be	sure	to	use	this	projector	at	an	altitude	of	less	
than 1500 meters.
