Panasonic PT-DZ21K2 Operating Instructions Manual page 19

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/LAN> terminal using a piece of metal foil or a metal pipe which is grounded at both ends.
rFocus adjustment
The high clarity projection lens is thermally affected by the light from the light source, making the focus unstable in
the period just after switching on the power. It is recommended that images be projected continuously for at least
30 minutes before the focus is adjusted.
rDo not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
Doing so may shorten the life of the components and result in malfunctions.
rDo not use the projector tilted to the right or left.
Using the projector at a vertical angle that exceeds ±15° may reduce the life of components or result in
malfunctions.
rWhen using the Replacement lamp unit (for portrait mode), install the projector with
the terminals surface facing down.
(Only for PT-DZ21K2, PT-DS20K2, PT-DW17K2)
Do not use the projector tilted to the right and left, front and back. Using the projector at an angle that exceeds 15°
in either direction may reduce the life of the components or result in malfunctions.
The PT-DZ16K2 cannot be used with the portrait installation.
rCautions when setting up the projector
f Use the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other
purposes may damage the projector.
f The adjustable feet can be removed if not needed in the installation. However, do not use the screw holes
where the adjustable feet were removed to fix the projector in place.
Also, insert only the screws that are specified in the user manual of the optional accessories into the screw
holes of the adjustable feet. Failure to do so may cause damage to the projector.
f When installing the projector in a location other than on the floor using the adjustable feet or the ceiling mount,
secure the projector using the six screw holes for ceiling mount (as shown in the figure).
(Screw diameter: M6, tapping depth inside the projector: 30 mm (1-3/16"), torque: 4 ± 0.5 N·m)
