Panasonic Projector Pt Lb20su Operating Instructions

							ENGLISH-11
Preparation
Before use
Caution when moving the projector
Be sure to attach the lens cover before moving the projector.
The projection lens is extremely susceptible to vibration and shocks. When
moving the projector, use the accessory carrying bag. When placing the
projector inside the carrying bag, position it so that the lens is facing upward.
Do not put anything else in the bag other than the projector and the cables.
Cautions regarding setting-up
Avoid setting up in places which are subject to vibration or shocks.
The internal parts can be damaged, which may cause malfunctions or
accidents.
Avoid setting up in places which are subject to sudden temperature
changes, such as near an air conditioner.
The life of the lamp may be shortened.
Do not set up the projector near high-voltage power lines or near
motors.
The projector may be subject to electromagnetic interference.
If installing the projector to the ceiling, ask a qualified technician to
carry out all installation work.
You will need to purchase the separate installation kit (Model No.ET-PKB30).
Furthermore, all installation work should only be carried out by a qualified
technician.
If using this projector at high elevations (above 1 400 m), set the “FAN
CONTROL” to “HIGH”. (Refer to page 47.)
Failure to observe this may result in malfunctions.

Notes on use
In order to get the best picture quality
Draw curtains or blinds over any windows and turn off any lights near the
screen to prevent outside light or light from indoor lamps from shining onto
the screen.
Do not touch the surfaces of the lens with your bare hands.
If the surface of the lens becomes dirty from fingerprints or anything else, this
will be magnified and projected onto the screen. Moreover, when not using
the projector, retract the lens and then cover it with the lens cover.
Screen
Do not apply any volatile substances which may cause discoloration to the
screen, and do not let it become dirty or damaged.
Lamp
The lamp may need to be replaced earlier due to variables such as individual
lamp characteristics, usage conditions and the installation environment,
especially when the projector is subjected to continuous use for more than
10 hours or the power is frequently turned on and off.
Liquid crystal panel
The liquid crystal panel of the projector is built with very high precision
technology to provide fine picture details. Occasionally, a few non-active
pixels may appear on the screen as fixed points of blue, green or red.
Please note that this does not affect the performance of your LCD.

NOTE:
BDuring projection of an image, the cooling fan will operate, emitting a
small noise as it operates. This noise may change depending on the
ambient temperature. Turning the lamp on or off will cause this noise to
increase a little.
BBy using the “OPTION” menu to set “LAMP POWER” to “LOW”, the
operating sound of the fan can be reduced. (Refer to page 47.)
