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 page 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 display "Options | Lamp Settings" menu after replacing the lamp module (see page 47).
Warning - When switching the projector off, 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 the end of its life, the projector will not turn back on until the lamp module has been replaced. To replace the lamp, follow the procedures listed under "Replacing the Lamp" section on page 56.

Do:

• Turn off the product before cleaning.
  Use a soft cloth moistened with a mild detergent to clean the display housing.
• Disconnect the power plug from the AC outlet if the product is not being used for a long period of time.

Don't:

Do not block the ventilation slots and openings on the unit.
Do not use abrasive cleaners, waxes or solvents to clean the unit.
Do not use under the following conditions:

- In extremely hot, cold or humid environments. Ensure that the ambient room temperature is within 5-40 °C and relative humidity is 10-85% (max.), non-condensing.

• In areas susceptible to excessive dust and dirt.
• Near any appliance that generates a strong magnetic field.
• In direct sunlight.

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 floor 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.
