1. The light source of the projector uses lasers.

   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 danger, 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 (LD units) 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 [PROJEC-

TOR SETUP] menu → [ECO MANAGEMENT] → [OPERATING MODE].

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

    (The time is estimated when the [PICTURE] menu → [DYNAMIC CONTRAST] is set to [ON].)

  

  •  These times are rough estimate when the projector is used without changing the [OPERATING MODE] setting, and will 

vary depending on individual difference and usage condition.

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 appropriate 

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.

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

 

  Lithium battery : CR2032

* Use only specified lithium battery.

* Used battery must be scrapped according to the instruction.

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

SETUP].

  The basic service policy is shown below.

1. Hexalobe (TORX type) driver [2.72 mm]

  • VESSEL T10H or comparable product

  • Part No. : TZSH07035

2. Hexalobe (TORX type) driver [3.94 mm]

  • VESSEL T20H or comparable product

  • Part No. : TZSH07042

3. Hex wrench/Hex ball-point driver 

  •[2.5mm] : Use for the lighting area adjustment.

  •[3.0mm] : Front cover removal.

4. Laser safety glass

  • Please wear glasses for safety when checking with the cover removed.

  • Type : Full absorption, Adaptation laser : Ar, Wavelength : 448 - 462nm

  • Part No. : TZSH07038 (or comparable product)

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.

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.

1.  When the replacement of [A]-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 [A]-P.C.Board.

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

  * Download the service software from Projector service web site.

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

[Note] 

•  If you cannot transfer the data by using the software, remove the [IC2008] on the original board and mount it on the new 

board.

•To revert to the factory default password (AAAA), perform the following operations while the screen asking for a control

 device password input is displayed.
  1.  Press the [AUTO SETUP] button on the remote control (or [p]+[INPUT SELECT] buttons on the control panel) for more 

than 3 seconds.

  2. Press the [▼] button for more than 3 seconds.

  The password will be initialized.

•Initial password : Press [p u q t p u q t] button sequentially and press [ENTER] button.

  If the initial password has been changed, ask user to have it.
