1. Safety Precautions
1. Be sure to read this manual before servicing and save it for future reference.
2. The lamp becomes extremely hot during operation. Allow the projector to cool for
approximately 45 minutes prior to removing the lamp assembly for replacement. Do not
operate lamps beyond the rated lamp life. Excessive operation of lamps beyond the
rated life could cause them to explode on rare occasions.
3. Never replace the lamp assembly or any electronic components unless the projector is
unplugged.
4. To reduce the risk of electric shock, do not disassemble this appliance. Take it to a
qualified technician when service or repair is required. Incorrect re-assembly can cause
electric shock when the appliance is subsequently used.
5. Do not place this product on an unstable cart, stand, or table. The product may fail,
sustaining serious damage.
2. Servicing Precautions
1. When replace the lamp, be sure to avoid burns your fingers because the lamp becomes
too hot.
2. Never touch the lamp bulb with a finger or anything else. Never drop it or give it a shock.
They may cause bursting of the bulb.
3. This projector is provided with a high voltage circuit for the lamp. Do not touch the
electric parts of power unit when turn on the projector.
4. Do not touch the exhaust fan during operation.

Appendix A Optical Measurement
This part of the Optical Test Instruction describes those measurements to be executed
during the production of the optical engines.
Content:
A1 BRIGHTNESS
A2 BRIGHTNESS UNIFORMITY
A3 BRIGHTNESS DIFFERENCE
A4 ANSI CONTRAST
A5 PEAK CONTRAST
A6 LIGHT LEAKAGE
A7 IMAGE DISTORTION
A8 THROW RATIO
A9 ZOOM RATIO
A10 FOCUS RANGE
A11 COLOR
A12 COLOR UNIFORMITY
A13 OPTICAL KEYSTONE (FIXED)
 General requirements
1. The unit shall be allowed to stabilize without further adjustment for a
minimum of 10 minutes, at nominal ambient room temperature of 25°C,
before making measurements.
2. Measurements shall take place in a light proof room, where the only source of
illumination is the projector. Less than 1% of the light on the screen shall be
from any source other than the projector.
3. All measurements shall be made on flat screens that do not provide any
advantage to the performance of the unit
4. All measurements shall be made at standard color temperature setting, 100%
white image (per ANSI IT7.228-1997), except where noted

 Practical consideration
1. When measuring contrast manually, operators should not wear white
clothing since light reflected from white clothing can influence the
measurement.
2. Unless otherwise specified the projection lens is set in the widest zoom
position since zoom function can influence the measurement.
3. Measurement should be performed with Minolta Chromameter, Model
CL-100, or equivalent.
 A1. BRIGHTNESS
Unit: Lumen
Brightness: Default
