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.

 

 

   

  

 

         

*1 :  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.

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.)

1. This projector is equipped with two SLOT NX-specification slots.

    “SLOT NX” is a name of the slot unique to Panasonic supporting the signal input for the 4K image.

2.  There are four SDI input terminals and one DIGITAL LINK input terminal equipped on this projector as the standard video 

input terminals.

    The input for HDMI, DVI-D, and SDI can be added by installing the optional Interface Board in the slot.

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.

g

 The component may be damaged by the static electricity.

f

 Remove the static electricity from your body by touching to surrounding metal, etc., in advance to prevent the 

static electricity damage.

f

 Take care not to get injured when installing or removing the Interface Board.

g

 Hands may be injured by the opening of the blank slot or the edge of the bracket of the Interface Board. 

f

 When installing the Interface Board to the slot, insert it into the connector straight and slowly.

g

 It may not operate or cause malfunction if it is not correctly installed.

f

 To use the 3G-SDI Terminal Board with Audio (Model No.: TY-TBN03G), it is necessary for the firmware version
