• Do not increase the volume unless you are listening while increasing the volume. Also, lower
the volume before turning off the power, because a loud sound may be emitted when the
power is turned on and cause hearing damage.
• Do not tilt the machine horizontally more than ±20 degrees. Doing so may cause the entrance
of foreign objects in the housing of the machine which could result in fire or electric shock.
The projector can be installed at any vertical angle. However, the projector cannot be tilted to the left or
right. Do not use the projector horizontally inclined (±20 degrees or greater).
