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.

 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

All manuals and user guides at all-guides.com

 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
