1. LD(Laser) unit that is mounted on the inside of the light source unit is classified in Class 4 of the safety standards.

     • Laser light is very dangerous, can damage the human eye and skin.

     • Please do not perform energization in the state where the lighting block was disassembled.

2. Depending on the operating environment temperature, the luminance of the light source will decrease.

    The higher the temperature becomes, the more the luminance of the light source decreases.

3. The luminance of the light source will decrease by duration of usage.

   •  The time until when the luminance of the light source decreases by half differs depending on the setting of the [PRO-

JECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE].

   • The estimated time until when the luminance of the light source decreases by half is as follows.

 

      

   

 

•  The runtime is an estimation when the [PICTURE] menu → 

[DYNAMIC CONTRAST] is set to [3].

   •  The foregoing time is a rough estimate when the projector is used without changing the settings of [OPERATING 

MODE] and [CONSTANT MODE], and will vary depending on individual differences and usage conditions.

4. Static electricity or electrical surges will reduce and degrade the reliability of LD unit.

   •  When working with the LD unit take countermeasures to avoid the generation of static electricity, use or wear appropri-

ate work clothes, gloves, shoes, grounded wrist straps and other tools to avoid static electricity.

1. The DMD chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit.

   • Note that such phenomena do not indicate malfunction.

2. Directing a high-power laser beam onto the projection lens surface can damage the DMD chips.

OPERATING MODE

Estimated time

NORMAL

Approx. 20 000 hours

ECO

Approx. 24 000 hours

1. The lithium battery is used for the internal clock in the A-P.C.Board. So when it consumed it must be replaced.

 

2.  After replacing the lithium battery, surely set the [DATE AND TIME] on the sub-menu in the main menu [PRPJECTOR 

SETUP].

1. Make sure that all the connectors are connected completely.

2. Especially, pay attention for the connection of the connectors on the LD unit.

   If the projector is turned on in the state of the connectors disconnected, the LD error will occur and be memorized in the

   memory. The error information will not be reset even if the connector is re-connected correctly.

   In this case, you need to take the runtime reset of its LD unit by the LD reset software.

   (The LD error information will also be reset.)

 Lithium battery : CR2032

• Use only specified lithium battery. 
• Used battery must be scrapped according to the instruction

.

1. Energization check and adjustment, after assembling the lighting block completely.

 

• Before turning on the power, please make sure that the lighting block is completely assembled.

•    The service engineer who works on this model and also other people who are in the same room need 

to wear the laser safety glasses for avoiding the laser irradiation just in case.

2. Do not disconnect the AC cord or turn off the AC breaker during the fans are operating.

   • Turn off the power after the POWER indicator lights red.

3. Before repair, make sure to turn off the main power and unplug the power cord from the power outlet.

   •  When replacing the print board, the internal electrical parts can be broken by the static electricity of clothes or human 

body. Be careful of static electricity and wear the anti-static electricity gloves.

4. After repairing, please check the gradation (10step or the gray scale) test pattern or moving image.

   • Also, please check that it is normal on a self check screen.

5. Do handling and safekeeping carefully because the user setup information remains in the projector.

• The filter is supplied as service parts. 

• When using the projector in a dusty area, use this filter to prevents dust from entering the inside (electrical circuit part).

  1.  Filter unit model No. : 3YE2RZ21K

• This filter can not be used when high altitude (over 1,400 m above sea level) and operating ambient 

   temperature is 35 ° C or more (at portrait 30 ° C or more). 

• Please use the voltage at AC 200 - 240 V.

1.  When the replacement of [A]-P.C.Board or [DG]-P.C.Board (assembly) is needed, back up the memory information such 

as adjustment data from the old board to PC with the service software. Then transfer this data to the new P.C.Board.

    For more information refer to the SECTION 3 "Adjustment".

2.  When replacing the [A] or [DG] printed circuit board, write the latest version of main firmware again to make consistency 

between Main and FPGA firmware. Each FPGA firmware is updated at the same time as the main firmware.

•  If you cannot transfer the data by using the software, remove the memory IC on the original board and mount it 

on the new board. 

  In the case of replacing the [A]-P.C.Board    : IC3711/IC3712 

  In the case of replacing the [DG]-P.C.Board : IC5412

• When [A]-P.C.Board is replaced, the MAC address of wired LAN will be changed. Explain it to the customers 

  in advance.
