Before installing or removing the lens unit, be sure to disconnect the power plug or connector. Failure to do so may result in fire, electric shock, or injury.
- When hanging the projector from a ceiling, put the projector down on the floor or a workbench before attaching or replacing the lens unit. Failure to do so could result in parts falling off the projector and may cause a malfunction or personal injury.
- Do not attempt to install or remove the lens unit yourself. Be sure to request this service from a qualified technician or contact the Canon Customer Support Center.

- The projector is provided with a lens shift function to move the lens up, down, left, and right using the motor. Do not touch the lens while it is moving. Touching the lens when it is moving may result in personal injury.
- Before replacing the lens unit, wait at least 30 minutes after the projector is turned off to allow the lens unit to cool down. Failure to do so may result in burns or injury.

- When installing and removing the lens unit, be sure not to touch the surface of the lens with your hands or scratch it.
- Do not apply force to parts (e.g. lead wires) that are connected to the lens unit or lens motor. Doing so may cause a malfunction.
- Do not replace the lens unit in a dusty location. If any dust or dirt enters the projector, this may adversely affect picture quality.
- When carrying or holding up the projector after attaching the lens unit, be sure not to hold the lens. Doing so may cause damage to the lens unit.
- If transportation is necessary, the lens unit should be removed before transporting the projector. If the projector is subjected to excessive impacts during transportation, the lens unit may be damaged.
- For details about which devices the projector is compatible with, contact the Canon Customer Support Center.
