Notes on repairing
 
f
In case of fuse opening inside the projector, Do not turn the projector on just replacing the fuse with a 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 whether 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 carefully by its bottom and avoid excessive vibration and impacts. They 
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.
 
f
Do not move or transport the projector with the wireless module (Model No.: ET-WML100) of the optional accessories attached. Doing so 
may damage the wireless module.
Cautions when installing
 
r
Do not set up the projector outdoors.
The projector is designed for indoor use only. 
 
r
Do not set up the projector in the following locations.
 
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 from the air conditioner. 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 lamp): Doing so may shorten the life of the 
luminous lamp, or result in deformation of the outer case due to heat, which may cause malfunctions. 
Follow the operating environment temperature of the projector.
 
f
Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
 
r
ask a qualified technician or your dealer for the installation work such as installing to a 
ceiling, etc.
To ensure projector performance and safety, ask a qualified technician or your dealer when installing to a ceiling or 
in a high place.
 
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 be projected continuously for at least 30 min-
utes before the focus is adjusted.
 
r
When using the projector in the elevation of below 1 400 m (4 593'), make sure [HIGH 
ALTITUDE MODE] is set to [OFF].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
 
r
When using the projector in the elevation of above 1 400 m (4 593') and below 2 000 m (6 
562'), make sure [HIGH ALTITUDE MODE] is set to [HIGH1].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
 
r
When using the projector in the elevation of above 2 000 m (6 562') and below 2 700 m (8 
858'), make sure [HIGH ALTITUDE MODE] is set to [HIGH2].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
 
r
Do not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
Failure to do so may shorten the life of the internal parts and result in malfunctions.

r
Do not tilt the projector or place it on its side.
Do not tilt the projector body more than approximately ±40° vertically or ±15° horizontally. Over tilting may result in 
shortening the life of the components.
The angle that can be corrected through [POSITION] menu → [SCREEN ADJUSTMENT] → [KEYSTONE] is within 
±35°. If the vertical tilt of the projector with respect to the screen surface exceeds 35°, vertical trapezoidal distortion 
may not be fully corrected.
 
r
Cautions when setting up the projectors
 
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
Do not stack the projectors.
 
f
Do not use the projector supporting it by the top.
 
f
Do not block the ventilation ports (intake and exhaust) of the projector.
 
f
Avoid heating and cooling air from the air conditioning system directly blow to 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 parts (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 for 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 be resulted.
  - Because the high pressure lamp involves a risk of failure, never touch the lamp wire lead during the service.
