Panasonic PT-REZ12 Operating Instructions Manual page 25

f Places with sharp temperature fluctuations such as near lights (studio lamps): Doing so may shorten the life of
the light source, or result in deformation of the projector due to heat, which may cause malfunctions.
Follow the operating environment temperature of the projector.
f Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
f Places where there is high-power laser equipment: Directing a laser beam onto the projection lens surface
causes damage to the DLP chips.
rAsk a qualified technician or your dealer for the installation work such as installing to
a ceiling.
To ensure projector performance and security, ask a qualified technician or your dealer when installing the
projector in a method other than the floor installation or when installing the projector in a high place.
rAsk a qualified technician or your dealer to install the cable wiring for DIGITAL LINK
connection.
Image and sound may be disrupted if cable transmission characteristics cannot be obtained due to inadequate
installation.
rThe projector may not work properly due to strong radio wave from the broadcast
station or the radio.
If there is any facility or equipment which outputs strong radio waves near the installation location, install the
projector at a location sufficiently far from the source of the radio waves. Or, wrap the LAN cable connected to the
<DIGITAL LINK IN/LAN> terminal using a piece of metal foil or a metal pipe which is grounded at both ends. The
<DIGITAL LINK IN/LAN> terminal is a terminal equipped on the optional DIGITAL LINK Terminal Board (Model
No.: TY-SB01DL).
rImage adjustment after installation
Projected image of the projector is affected by the ambient temperature around the projector or the increased
internal temperature caused by the light from its light source, and it will be unstable especially right after the
projection has started.
It is recommended to perform the focus adjustment after 30 minutes have elapsed with the focus test pattern
displayed. For details of the test pattern, refer to "[TEST PATTERN] menu" (x page 192).
rDo not install the projector at an altitude of 4 200 m (13 780') or higher above sea
level. (Altitude of 4 200 m (13 780') above sea level is the maximum height that the
performance of this projector is guaranteed.)
rDo not use the projector in a location where the ambient temperature exceeds 45 °C
(113 °F).
Using the projector in a location where the altitude is too high or the ambient temperature is too high may reduce
the life of the components or result in malfunctions.
Upper limit of the operating environment temperature varies depending on the altitude above sea level.
When using the projector at an altitude between 0 m (0') and 1 400 m (4 593') above sea level: 0 °C (32 °F) to
45 °C (113 °F)
When using the projector at an altitude between 1 400 m (4 593') and 4 200 m (13 780') above sea level: 0 °C
(32 °F) to 40 °C (104 °F)
Do not use the projector in a location where the ambient temperature exceeds 40 °C (104 °F) regardless of the
altitude when the optional Wireless Module (Model No.: AJ-WM50 Series) is attached to the projector.
