Chapter 1 Preparation — Precautions for use
ENGLISH - 21
Early Warning Software
The projector supports “Early Warning Software” which noties of abnormality and detects signs of possible abnormality by
monitoring the status of equipment (projectors or at-panel displays) inside an intranet. Because this software gives notication
of approximate time to replace consumables and parts, and to clean each part, equipment maintenance can be performed in
advance.
Depending on the type of license, the number of equipment that can be registered for monitoring varies. Limited to the rst 90
days after installation in a computer, it is possible to register up to 2048 units of equipment free of charge.
The software can be downloaded for free from the Panasonic website for membership support system “PASS (Projector Asset
Support System)” (http://panasonic.net/avc/projector/pass/). First sign up for “PASS” membership (free of charge), and then log
in to the site.
Disposal
To dispose of the product, ask your local authorities or dealer for correct methods of disposal.
Cautions on use
rTo get a good picture quality
In order to view a beautiful image in higher contrast, prepare an appropriate environment. Draw curtains or blinds over
windows and turn off any lights near the screen to prevent outside light or light from indoor lamps from shining onto the screen.
rDo not touch the surface of the projection lens with your bare hands.
If the surface of the projection lens becomes dirty from ngerprints or anything else, this will be magnied and projected onto
the screen.
Attach the lens cover supplied with the projector or with the optional projection lens to the projector when you do not use the
projector.
rDLP chips
f The DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit. Note that
such phenomena do not indicate malfunction.
f Directing a high-power laser beam onto the projection lens surface can damage the DLP chips.
rDo not move the projector or subject it to vibration or impact while it is operating.
Doing so may shorten the life of the built-in motor.
rLight source
The light source of the projector uses lasers, and has the following characteristics.
f Depending on the operating environment temperature, the luminance of the light source will decrease.
When using the projector at elevations lower than 2 700 m (8 858') above sea level, and the operating environment
temperature becomes 35 °C (95 °F) or higher, the luminance of the light source may decrease. When using the projector
at elevations between 2 700 m (8 858') and 4 200 m (13 780'), and the operating environment temperature becomes 25 °C
(77 °F) or higher, the luminance of the light source may decrease. The higher the temperature becomes, the more the
luminance of the light source decreases.
f The luminance of the light source will decrease by duration of usage.
The time until when the luminance of the light source decreases by half differs depending on the setting of the [PROJECTOR
SETUP] menu → [OPERATION SETTING] → [OPERATING MODE].
The estimated time until when the luminance of the light source decreases by half is as follows.
g When [OPERATING MODE] is set to [NORMAL]: Approximately 20 000 hours
g When [OPERATING MODE] is set to [ECO]: Approximately 24 000 hours
g When [OPERATING MODE] is set to [LONG LIFE1]: Approximately 43 000 hours
g When [OPERATING MODE] is set to [LONG LIFE2]: Approximately 61 000 hours
g When [OPERATING MODE] is set to [LONG LIFE3]: Approximately 87 000 hours
When the [PROJECTOR SETUP] menu → [OPERATION SETTING] → [CONSTANT MODE] is set to [AUTO], the luminance
can be maintained as much as possible for the same usage time. The foregoing time is a rough estimate when the projector
is used without changing the settings of [OPERATING MODE] and [CONSTANT MODE], and will vary depending on
individual differences and usage conditions.
If brightness is noticeably reduced and the light source does not turn on, ask your dealer to clean inside the projector or
replace the light source unit.
