Panasonic DLP Projector PT-DZ21K2 PT-DS20K2 PT-DW17K2 PT-DZ16K2 Operating Instructions

							Chapter 1 Preparation — Preparing the remote control
ENGLISH - 31
Connecting the remote control to the projector with a cable
If you control the multiple projectors with a single remote control, use commercially available M3 stereo mini jack 
cables to connect to the / terminals of the projectors.
The remote control is effective even in places where an obstacle stands in the light path or whe\
re devices are 
susceptible to outside light.
Connecting terminalsConnecting to a second projector
M3 stereo mini jack cable (commercially 
available)
Remote control
Connecting to the remote control wired 
terminal
Attention
 f Use a cable that is 15   m (49'3") or shorter, with 2 core shielded. The remote control may not operate when the length of the cable exceeds 
15   m (49'3") or when the shielding of the cable is inadequate.

Setting up
Installation mode
The installation modes of the projector are as follows. Set the [PROJECTOR SETUP] menu → [PROJECTION 
METHOD] (x   page   126) depending on the installation mode.
 fFor the portrait setting, use the optional Replacement lamp unit (for portrait mode) (Model No.: ET-

LAD520P 
(1
  pc), ET
-
 LAD520PF (4   pcs)). (Only for PT

Parts for ceiling mount (optional)
The projector can be installed on the ceiling by combining the optional Ceiling mount bracket (Model No.: 
ET
-
PKD520H (for high ceilings), ET
-
 PKD520S (for low ceilings)) and Ceiling mount bracket (Model No.: 
ET
-

PKD520B (Projector Mount Bracket)).
 fBe sure to use the ceiling mount bracket specified for this projector .
 fRefer to the Installation Instructions of the ceiling mount bracket when\
 installing and setting up the projector

.
Attention
 f To ensure projector performance and security, installation of the Ceiling mount bracket must be carried out by your dealer or a qualified 
technician.
Projected image and throw distance
Install the projector referring to the projected image size and projection distance. Image size and image position 
can be adjusted in accordance with the screen size and screen position. When the fixed-focus lens (Model No.: 
ET
-

D75LE90) is attached, the projection relation between the screen and the projector dif fers from that of other 
lenses. Refer to “For fixed-focus lens (Model No.: ET
-

D75LE90)” (x
  page   35) for details.

Attention
 fBefore setting up, read “Precautions for use” ( x   page   18).
Especially when the fixed-focus lens (Model No.: ET- D75LE90) is used, install the projector so that its back plane is parallel to the screen, 
making the projected image rectangular.
The vertical keystone distortion in moderate range can be corrected by the [POSITION] menu  → [GEOMETRY] → [KEYSTONE] → 
[VERTICAL KEYSTONE] (x
  page   94) even after the projector is installed. For the range that can be corrected, refer to “[GEOMETR Y] 
projection range” ( x
  page   36).
 fDo not use the projector and the high-powered laser equipment in the same room.  The DLP

 chips can be damaged if a laser beam hits the 
projection lens surface.
 f The dimension of L4 is not the distance between the rear of the projector body and the wall, but the distance between the rear of the 
projector body and the screen surface. Install the projector with 500

  mm (19-11/16") or larger space between the rear of the projector body 
and the wall or any object so that the ventilation is not obstructed.
When installing the projector in a confined space, provide air conditioning or ventilation separately . Exhaust heat may accumulate when the 
ventilation is not enough, triggering the protection circuit of the proj\
ector.

Note
 f When [GEOMETR Y] is used, the focus of the entire screen may be lost as correction increases. fMake the curved screen a circular arc shape with one part of a perfect circle removed. fAdjustment range of the [GEOMETR

Y] items may not match the listed projection range depending on the projection lens. Use this projector 
within the projection range, otherwise the correction may not work.
