PREFACE

<PT-JW130>

Any unauthorized changes or modifications to this equipment will void the users authority to operate.

■

Do not set up the projector in the following locations.

・

Do not set up the projector outdoors. The projector is designed for indoor use only.

・

Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare cases due to the heated

air from the air exhaust port or the hot or cooled air. Make sure that the exhaust from the projector or other equipment, or the air from

the air conditioner does not blow toward the front of the main unit of the projector.

・

Places with sharp temperature fluctuations near lights (such as studio lamps): Doing so may result in deformation of the projector 

due to heat, which may cause malfunctions.

The operating environment temperature of the projector should be between 0 °C (32 °F) and 40 °C (104 °F) when using it at 

elevations lower than 1 000 m (3 281') above sea level, and between 0 °C (32 °F) and 35 °C (95 °F) when using it at elevations

between 1 000 m (3 281') and 2 700 m (8 858') above sea level.

・

Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.

・

Places where there is high-power laser equipment: Directing a laser beam onto the lens surface causes damage to the DLP chips.

■

Cautions when setting up the projector

・

Mount the projector to the track system which is installed in the horizontal ceiling or beam and can withstand the weight of the projector.

・

Do not install the projector in a confined space, and do not block the ventilation ports (intake and exhaust) of the projector.

・

Prevent hot and cool air from the air conditioning system to blow directly to the ventilation ports (intake and exhaust) of the projector.

・

Make sure to set [HIGH ALTITUDE MODE] to [HIGH1] when using the projector at elevations between 1 000 m (3 281') and 

2 000 m (6 562') above sea level, and set [HIGH ALTITUDE MODE] to [HIGH2] when using the projector at elevations between 

2 000 m (6 562') and 2 700 m (8 858').

Do not install the projector at elevations of 2 700 m (8 858') or higher above sea level.

・

The 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.

 There are special parts used in Panasonic DLP Projectors which are important for safety. These parts are shaded on the schematic
 diagram. It is essential that these critical parts should be replaced with manufacturer’s specified parts to prevent shock, fire, or other
 hazards. Do not modify the original design without permission of Panasonic System Communications Company of North America.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following measures:
    ・Reorient or relocate the receiving antenna.
    ・Increase the separation between the equipment and receiver.
    ・Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
    ・Consult the dealer or an experienced radio/TV technician for help.

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.

- 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 combinations must be properly installed.
- After the service, check the leakage current to prevent the customer from getting an electric shock.
