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.

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) 1. 2. 3. 4.
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.

Appendix B Design Verification Test Procedure 1.Purpose This standard establishes the environmental specification for projector related products, which defines the level of product performance and reliability in the field. It is not necessary the intent of these specification to simulate a typical user environment, but rather to provide for a level of product robustness that when applied over a wide range of manufacturing variability and environmental usage conditions. 2.
3.Definition 3.1 Failure Criteria: The product is expected to perform to its full potential without loss of function, performance, critical parametric changes, and other undesirable anomalies, over the applied boundaries of this specification. The following product failure are not allowed within the boundaries defined in this specification: 1.Failure including permanent damage, critical parametic changes (optical performance defined in Appendix A), and latent defects. 2.

11. Firmware Upgrade Procedure 1. Connect specific download cable to RS232 (RJ-11) connector. Remember to turn the AC switch off. 2. Execute the ‘Flash Loader’ program. If the ‘COM Settings’ item is ready, you can see ‘Identifying target…’ at the bottom of flash loader. If not, open ‘COM Settings’ item. Choose the ‘COM Port’ you use, always set the baud rate 115200, then press ‘Connect’ and ‘OK’ button.
3. Turn the AC switch on. In 3 seconds, ‘flash loader’ will identify the flash ROM of this unit. Choose ‘Hex File Format’ as ‘Intel Extended’, ‘Operation’ as ‘Program’, and ‘Browse’ the ‘File Name’. After that, press the ‘Start’ button. ‘Flash Loader’ starts to load program to Flash ROM. 4. After download procedure finished, remove download cable and turn the AC switch off. Then the user can operate this machine in normal condition. The hex file to be loaded, the format of its name is 5.
12. RS232 Codes 1. Set up peripherals BenQ PE8700 provides an RJ-11 connector for RS232 serial communication control. The user can use the ‘Hyper Terminal’ program of Microsoft Windows to control this unit. To set the settings of serial port first is necessary.
After settling down, connect our specific RS232 cable and press the ‘call’ icon of ‘Hyper Terminal’ program. After this, press ‘Enter’ key, if an ‘>’ symbol come up, that means the unit is ready to accept commands for computer. 2. Commands list There are 3 kinds of serial commands, X-group, Y-group and Z-group. For X-group, these functions are public. Any end-user can control the unit by these commands, as long as they set correct RS232 communication. Following table is the codes list of X-group command.

Example: 1. Command = Y89893 (Enter) ACK = Y1Y (Illegal format, wrong length) 2. Command = Y98 (Enter) ACK = Y2Y (Illegal function) 3. Command = Y52 (Enter) 1st ACK = Y0Y 2nd ACK = Y0_52Y For Z-group, this one is for ‘auto-alignment’ procedure in our factory. This one allows engineers to read or write the unit settings without OSD operation, it will save time to set the value. Following is the table of Z-group.
Z030 Keystone adjustment Z034 RGBHV input -- Red offset Z035 RGBHV input -- Green offset Z036 RGBHV input -- Blue offset Z037 RGBHV input -- Red gain Z038 RGBHV input -- Green gain Z039 RGBHV input -- Blue gain Z042 YPbPr input -- Brightness Z043 YPbPr input -- Contrast Z044 YPbPr input -- Saturation Z045 YPbPr input -- Pb Offset Z046 YPbPr input -- Pr Offset Z050 CVBS & S-Video -- Brightness Z051 CVBS & S-Video -- Contrast Z052 CVBS & S-Video -- Saturation Z053 CVBS & S-Video

And the length of ACK must be 12, and format is Z0_072+0025Z Byte 1: Always ‘Z’ Byte 2: ACK Byte 3: Always ‘_’ Byte 4~6: function code Byte 7: sign byte, ‘+’ or ‘-‘ Byte 8~11: the current value after writing Byte 12: Always ‘Z’ And ‘ACK’ value is 0: Right command and function 1: Illegal Format 2: Illegal Function 3: Illegal Action, 4: Illegal Adjusted Situation, 5. Written value is over up limit, 6. Written value is over down limit If the ACK is 0, 5, 6, program will deal this command.
