N OTES ON USE
• The projector uses a high-voltage mercury lamp that contains high
internal pressure. This lamp may break, emitting a large sound, or
fail to illuminate, due to impact or extended use. The length of
time that it takes for the lamp to break or fail to illuminate varies
greatly depending on individual lamp characteristics and usage
conditions.
• The brightness of the lamp will gradually decrease with use.
• The lamp, LCD panel, polarising plate, and polarising beam splitter
(PBS) are consumable parts. These parts may need to be replaced
during the guarantee period if the projector is used for six or
more hours per day.
• The replacement cycle of the LCD panel, polarising plate, and
polarising beam splitter (PBS) will be shortened if the projector is
subjected to continuous use for six or more hours. Likewise, the
replacement cycle of the lamp will be shortened if the power is
frequently turned on and off or the projector is subjected to con-
tinuous use for 10 or more hours.
• Interruptions may occur in the wireless connection due to signal
interference or PC conditions.
*1: In AI mode.
*2: Legs and protruding parts not included.
*3: Operation range differs depending on the environment.
*4: For the PT-LB50NTEA only.
Ecology-Conscious Design
Panasonic works from every angle to minimise envi-
ronmental impact in the product design, production
and delivery processes, and in the performance of the
product itself over its life cycle. The PT-LB50 Series
reflects the following ecological considerations.
• Lead-free solder is used to mount components to
the printed circuit boards.
• No halogenated flame retardants are used in the
cabinet.
• No styrofoam is used in the packing materials.
• Lead-free glass is used for the lens.
• The packing case and operating manual are made
from recycled paper.
