Cautions when transporting

・

When transporting the projector, move the lens position to the home position and attach the lens cushion.

  If lens optional model, move the lens position to the home position, remove the projection lens, and then attach
  the lens hole cover.
・

Unpacking and carrying should be done by at least two persons.

・

When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts.

  They may damage the internal components and result in malfunctions.
・

Do not transport the projector with the adjustable feet extended.

  Doing so may damage the adjustable feet.

■

Do not set up the projector in the following locations.

・

The projector is designed for indoor use only.

・

Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal

  components or malfunction.
・

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 projector.
・

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 outer case due to heat, which may cause malfunctions.
・

The operating environment temperature of the projector should be between 0 °C (32 °F) and 45 °C (113 °F).

・

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.

■

Note at the time of installation

・

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.
・

Be sure to set [HIGH ALTITUDE MODE] to [OVER 2700m] when using the projector at elevations between

  2 700 m (8 858') and 4 200 m (13 780') above sea level.
  Make sure to set [HIGH ALTITUDE MODE] to [UNDER 2700m] when using the projector at elevations lower
  than 2 700 m (8 858') above sea level.
  Do not install the projector at elevations of 4 200 m (13 780') or higher above sea level.
・Set [COOLING CONDITION] according to the projection direction, but set it to [AUTO] most commonly.
  Using the projector with [COOLING CONDITION] set incorrectly may shorten the life of the light source.
  Check the setting from [COOLING CONDITION] on the [STATUS] screen.

 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 A digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own
expense.

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.
