Notes on repairing
f
In case of fuse opening inside the projector, Do not turn the projector on just replacing the fuse with new one be-
cause there might be a possibility to have smoking or firing hazard. Turn it on after solving the main cause of fuse
opening.
f
After repairing, confirm that the projector operates correctly.
f
Pay attention to handle the projector as customer's personal settings have been remaining inside the projector.
Cautions when transporting
f
When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts.
Doing so may damage the internal parts and result in malfunctions.
f
Do not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.
Cautions when installing
r
Do not set up the projector outdoors.
The projector is designed for indoor use only.
r
Do not use under the following conditions.
f
Places where vibration and impacts occur such as in a car or vehicle: Doing so may damage the internal parts
and result in malfunctions.
f
Location close to sea or where corrosive gas may occur: the projector may fall due to corrosion. Also, failure to do
so may shorten the life of the components and result in malfunction.
f
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.
f
Places with sharp temperature fluctuations such as near lights (studio lamps): Doing so may shorten the life of the
luminous lamp, or result in deformation of the outer case due to heat, which may cause malfunction. Make sure to
observe the operating temperature range of the projector.
f
Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
r
Be sure to ask a specialized technician or your dealer when installing the product to a
ceiling.
This requires an optional ceiling mount bracket. Be sure to use the Projector Mount Bracket together with the ceiling
mount bracket for high ceilings or low ceilings.
r
Ask a qualified technician or your dealer to install the cable wiring for DIGITAL LINK
connection.(Only for PT-VZ585N,PT-VW545N,PT-VX615N)
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.(Only for PT-VZ585N,PT-VW545N,PT-VX615N)
If there is any facility or equipment which outputs strong radio waves near the installation location, install the projec-
tor at a location sufficiently far from the source of the radio waves. Or, wrap the LAN cable connected to the <DIGI-
TAL LINK/LAN> terminal using a piece of metal foil or a metal pipe which is grounded at both ends.
r
Focus adjustment
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 the images are projected continuously for at least 30 min-
utes before the focus is adjusted.
r
Do not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
r
Do not use the projector in a location that the ambient temperature exceed 40 °C
(104 °F).
Using the projector in a location that the altitude is too high or the ambient temperature is too high may shorten the
life of the components or result in malfunctions.
The upper limit of the operating temperature of the projector varies depending on the altitudes of the operating envi-
ronment.

When using it at altitudes below 1 200 m (3 937') above sea level: 0 °C (32 °F) ~ 40 °C (104 °F)
When using it at altitudes between 1 200 m (3 937') and 2 700 m (8 858') above sea level: 0 °C (32 °F) ~ 30 °C
(86 °F).
r
Do not tilt the projector or place it on its side.
Do not tilt the projector body more than approximately ±30 degrees longitudinally or ±15 degrees laterally. Over
tilting may result in shortening the life of the components.

Cautions when setting the projectors
f
Use the adjustable feet only for the oor standing installation and for adjusting the angle. Using them for other
purposes may damage the projector.
f
Do not stack the projectors.
f
Do not use the projector supported by its top.
f
Do not block the ventilation ports (intake and exhaust) 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 combinations 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.

1.3. UV Precaution and UHM Lamp Precautions
- Be sure to unplug the power cord from the power outlet when replacing the lamp.
- Because the lamp reaches a very high temperature during its operation, wait until it cools completely when replacing the Lamp Unit.
- The lamp emits small amounts of UV-radiation, avoid direct-eye contact with the light.
- The lamp unit has high internal pressure. If improperly handled, explosion might result.
- Because the high pressure lamp involves a risk of failure, never touch the lamp wire lead during the service.
