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.
