maintenance as recommended in this user’s

guide.

▀■ Warning - Do not look into the projector’s lens when the lamp is

▀■ Warning - To reduce the risk of re or electric shock, do not

expose this projector to rain or moisture.

▀■ Warning - Please do not open or disassemble the projector as

this may cause electric shock.

▀■ Warning - When replacing the lamp, please allow unit to cool down,

and follow all replacement instructions. See pages 56.

▀■ Warning - This projector will detect the life of the lamp itself. Please

be sure to change the lamp when it shows warning

messages.

▀■ Warning - Use the “Lamp Reset” function from the on-screen dis-

play “Options|Lamp Setting” menu after replacing the lamp

module (see page 47).

▀■ Warning - When switching the projector o, please ensure the

cooling cycle has been completed before disconnecting

the power. Allow 90 seconds for the projector to cool

down.

▀■ Warning - Do not use the lens cap when projector is in operation.

▀■ Warning - When the lamp is approaching the end of its life, the

message “Lamp is approaching the end of its useful

life” displays on the screen. Please contact your local

reseller or service center to change the lamp as soon

as possible.

▀■ Warning - To reduce the risk of injury to the eyes, do not look directly

into the laser beam on the remote control and do not point

the laser beam into anyone’s eyes. This remote control is

equipped with a Class II laser that emits radiation.

When the

lamp reaches

Eye Safety Warnings

▀■ Avoid staring directly into the projector’s beam of light at all times.

▀■ Minimize standing facing into the beam. Keep your back to the

beam as much as possible.

▀■ Using a stick or laser pointer is recommended to avoid the need

for the presenter to enter the beam.

▀■ Ensure that projectors are located out of the line of sight from

the screen to the audience; this ensures that, when presenters

look at the audience, they do not also have to stare at the

projector lamp. The best way to achieve this is by ceiling-

mounting the projector rather than placing it on oor or table

top.

▀■ When projector is used in a classroom, adequately supervise

students when they are asked to point out something on the

screen.

▀■ In order to minimize the lamp power needed, use room blinds to

reduce ambient light levels.
