r
Be sure to ask a specialized technician or your dealer when installing the projector on 
a ceiling.
The optional Ceiling Mount Bracket is required.
Model No.: ET-PKD120H (for High Ceilings), ET-PKD120S (for Low Ceilings), ET-PKD130H (for High Ceilings, 
6-axis Adjustment), ET-PKD130B (Projector Mount Bracket)
 
r
Ask 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.
 
r
The 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.
 
r
Focus 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.
 
r
Do not install the projector at an altitude of 4 200 m (13 780') or higher above sea level.
 
r
Do not use the projector in a location that the ambient temperature exceeds 45 °C 
(113 °F).
Using the projector in a location that the altitude is too high or the ambient temperature is too high may reduce the 
life of the components or result in malfunctions.
 
r
Projection in all 360° direction is possible.

r
The geometric adjustment function is disabled when projecting the input signal 
rotated by 90°. (Only for PT‑RW730, PT‑RW620)
The geometric adjustment function cannot be used when projecting the input signal rotated by 90°. When 
installing the projector, follow the following instructions to prevent distortion in the projected image.
f
 Use a flat screen.
f
 Install the projector so that the front side of the projector is parallel to the screen.
f
 Install the projector so that the image can be projected within the range of shift adjustment by moving the lens 
position.
The 90° rotation of the image can be set in the [DISPLAY OPTION] menu → [IMAGE ROTATION].

r
 Cautions 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
 When installing the projector with a method other than the floor installation using the adjustable feet, top placed
   on the floor, or the ceiling installation, use the five screw holes for ceiling mount (as shown in the figure) to fix  
   the projector to the mount.
   (Screw diameter: M6, tapping depth inside the projector: 12 mm (15/32"), torque: 4 ± 0.5 N·m)
f
 Do not install the projector in a confined space.
   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
   projector.

1. Safety Precautions
1. 1. General Guidelines
  - For continued safety, no modification of any circuit must be attempted.
  - Unplug the power cord from the power outlet before disassembling this projector.
  - Use correctly the supplied power cord and must ground it.
  - It is advisable to use an isolation transformer in the AC power line before the service.
  -  Be careful not to touch the rotation part (cooling fan, etc.) of this projector when you service with the upper case removed 
and the power supply turned ON.
  -  Observe the original lead dress during the service. If a short circuit is found, replace all the parts overheated or damaged 
by the short circuit.
  -  After the service, all the protective devices such as insulation barriers, insulation papers, shields, and isolation R-C combi-
nations must be properly installed.
  - After the service, check the leakage current to prevent the customer from getting an electric shock.
1. 2. Leakage Current Check
  1. Prepare the measuring circuit as shown in Fig.1.
    Be sure to use a voltmeter having the performance described in Table 1.
  2. Assemble the circuit as shown in Fig. 2. Plug the power cord in a power outlet.
  3. Connect M1 to T1 according to Fig. 2 and measure the voltage.
  4. Change the connection of M1 from T1 to T2 and measure the voltage again.
  5.  The voltmeter must read 0.375 V or lower in both of steps 3 and 4. This means that the current must be 0.75mA or  less.
  6.  If the reading is out of the above standard, the projector must be repaired and rechecked before returning to the customer 
because of a possibility of an electric shock.
