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 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 cap to the lens when not using the projector, to prevent the lens from becoming dirty or
damaged.
• The mercury lamp that is used as the projector's light source deteriorates as a result of normal use and as a
result of impacts or other damage, and may also break with a loud noise, stop working or reach the end of its
service life more quickly.
At such times, the amount of time remaining before the lamp breaks or stops working may vary greatly depending
on the individual lamp characteristics and the operating environment. These are normal characteristics of mercury
lamps. You should always have a spare lamp ready in case it is needed.
• YAMAHA takes no responsibility for loss or damage caused by damage to the projector or operating failures
outside normal service warranty conditions.
Lamp Operating Errors
The mercury lamp that is used as the light source for this projector may stop operating on occasions. This is a normal
characteristic of mercury lamps. If the lamp does not turn on when the projector's power is turned on, remove the
lamp and check if it is broken. If the lamp is not broken, reinstall it. Refer to "Replacing the Lamp" on page 48 of this
manual for instruction on removing and reinstalling the lamp.
If the lamp is broken, replace it with a new lamp. It is recommended that you have a spare lamp ready at all times in
case it is needed.
Notes on Carrying the Projector
• Turn off the projector power and then disconnect the power cord from the electrical outlet.
Furthermore, check that all other cables have been disconnected.
• Attach the lens cap to the lens.
• Retract the adjustable foot.
• If your model of projector has a handle, hold the projector by the handle when carrying it.
