Safety Instructions

The precautionary measures itemized below should be fully understood when performing repair and 
maintenance procedures.

When disassembling/assembling, be sure to turn off the power switch and pull out 
the power cable from the projector beforehand.

Never touch the current-carrying part or high temperature section during a test oper-
ation, signal measurement or any other situations that is necessary to perform the 
repair/maintenance work with the power turned on and the cover removed. 
Do not wear the metal products such as wrist watch, cuff buttons, rings, tiepin etc. to 
avoid getting a electric shock.

Do not touch the lamp assy. or the parts around it. They are extremely hot even after 
completed the cooling down operation, and may cause a burn injury.
Therefore, leave the unit until it becomes cool enough before performing mainte-
nance work.

Never let the safety devices mounted in this product inactivated for any reason what-
soever.

Never modify the safety devices or replace them with the ones that are not desig-
nated for any reason whatsoever. (Such actions may cause a fire or serious injury.)

Never modify the product for any reason whatsoever. (Except for a case that is under 
the instructions to do so.)

Never peer through the projection lens during repair/maintenance work when the 
power is on.
(Such an action may cause a visual disability because of a very strong light emis-
sion.)

Never use a deformed plug or a damaged power cable to this product. 
If any deformations or damages are found on the power cable or plug section, 
replace it with a new specified power cable.

Never use the air blowers that contain flammable gas in repair/maintenance work.
