Notes on Handling and Storage
Be sure to observe the following precautions to avoid malfunctions, operating
errors or damage to the projector.

Notes on Handling and Storage

• Do not use or store the projector in places which are subject to high and low
extremes of temperature. Furthermore, avoid places where the temperature
may change suddenly.
Be sure to observe the operating temperatures and storage temperatures given in
the User's Guide when using and storing the projector.
• Do not project images while the lens cover is still attached. If projection will be
obscured for a short period, turn on the A/V Mute function; if it will be
obscured for a long period, turn the power off and then turn it back on again.
• Do not set up the projector in places where it might be subjected to vibration
or shocks.
• Do not set up the projector near high-voltage electrical wires or sources of
magnetic fields.
These may interfere with correct operation.
• Do not touch the lens with bare hands.
If fingerprints or grease get onto the lens, it can interfere with the quality of the
projected images. Attach the lens cover to the lens when the projector is not in
use.
• During projection, some points (dots) may appear lit at all times, or they may
be dark at all times.
This is caused by the characteristics of the LCD panel, and is not a sign of a
malfunction. The LCD panel is manufactured using extremely high-precision
technology. However, black dots may appear on the panel, or some red, blue or
green dots may light extremely brightly at times. Furthermore, sometimes stripe-
shaped color irregularities or brightness irregularities may also appear.
• Remove the batteries from the remote control before storage.
If the batteries are left in the remote control for long periods, they may leak.
• Always attach the lens cover to the lens when not using the projector, to
prevent the lens from becoming dirty or damaged.
• Do not use or store the projector in places where smoke from oil fires or
cigarettes may be present, as it can adversely affect the quality of the
projected images.
