1 Safety Precautions

1.1. General Guidelines

· For continued safety, no modification of any circuit must be

attempted.

· Unplug the power cord from the power outlet before

disassembling this projector.

· Use correctly the supplied power cord and must ground it.

· It is advisable to use an isolation transformer in the AC

power line before the service.

· Be careful not to touch the rotation part (cooling fan, etc.) of

this projector when you service with the upper case removed and the power supply turned ON.

· Observe the original lead dress during the service. If a short

circuit is found, replace all the parts overheated or damaged by the short circuit.

· After the service, all the protective devices such as

insulation barriers, insulation papers, shields, and isolation R-C combinations must be properly installed.

· After the service, check the leakage current to prevent the

customer from getting an electric shock.

1.2. Leakage Current Check

1. Prepare the measuring circuit as shown in Fig.1. Be sure to use a voltmeter having the performance

described in Table 1.

PT-D10000U / PT-D10000E / PT-DW10000U / PT-DW10000E

Fig. 2

2. Assemble the circuit as shown in Fig. 2. Plug the power cord in a power outlet.

3. Connect M1 to T1 according to Fig. 2 and measure the voltage.

4. Change the connection of M1 from T1 to T2 and measure the voltage again.

5. The voltmeter must read 0.375 V or lower in both of steps 3 and 4. This means that the current must be 0.75 mA or less.

6. If the reading is out of the above standard, the projector must be repaired and rechecked before returning to the customer because of a possibility of an electric shock.

1.3. UV Precaution and UHM Lamp

Precautions

· Be sure to unplug the power cord from the power outlet when replacing the lamp.

· Because the lamp reaches a very high temperature during its operation, wait until it cools completely when replacing the Lamp Unit.

· The lamp emits small amounts of UV-radiation, avoid directeye contact with the light.

· The lamp unit has high internal pressure. If improperly handled, explosion might result.

PT-D10000U / PT-D10000E / PT-DW10000U / PT-DW10000E

7 Using a Wired Remote Control

7.1. Connection Example

When multiple main units are connected as part of the system, connect to units with a M3 stereo mini jack cable (sold separately) to simultaneously control multiple main units with a single remote control through the REMOTE1 IN/OUT terminal. It is effective to use the wired remote control in the environment in which an obstacle stands in the light path or where devices are susceptible to outside light.

· Use a two-wire shielded cable with a length of 15 m or less. If the length of the cable exceeds 15 m, the shielding of the cable

may not be sufficient and the remote control may not work.

7.2. Setting Projector ID Number to Remote Control

Every projector has its ID number and the ID number of the controlling projector must be set to the remote control in advance so that the user can operate the remote control. The ID number of the projector is set to “ALL” on shipping, and use the ID ALL button of the remote control when using only a single projector.

Procedure of ID setting

Press ID SET, and then within 5 seconds, press the two numeric (0-9) buttons which correspond to the ID number that has been set for the projector.

· The main unit has its ID number (1-64 or ALL), and set to remote control when the ID number is 1-9 as 01-09. When the

ID number is "ALL", set it with the ID ALL button of the remote control unit.

· Do not press the ID SET button accidentally or carelessly because the ID number on the Remote Control can be set even

when no projector is around.

· If you do not enter the two-digit ID number within 5 seconds after the ID SET button has been pressed, the ID number will

remain at the number that was set before the ID SET button was pressed.

· Your specified ID number is stored in the remote control unit unless another one is specified later. However, the stored ID

will be erased if the batteries of the remote control are left exhausted. When the batteries are replaced, set the same ID number again.

11 Replacement of Lamp Unit

Cautions

· Wait until the lamp is cooled sufficiently before replacing the lamp unit.

· Make sure that all four lamp units are installed.

· Replace of the lamp unit should be carried out by a qualified technician.

11.1. Precautions on Lamp Unit Replacement

Remove the power plug and confirm that the surroundings of the lamp unit have cooled off.

· Be careful when handling a light source lamp. The lamp unit has high internal pressure. If improperly handled, explosion might

result.

· A used lamp unit may burst if it is handled violently.

For disposition of used lamps, request an industrial waste disposal contractor.

· If you continue to use a lamp after the replacement time, the lamp may break.

· Philips screwdriver is necessary when replacing a lamp unit.

11.2. Timing of Lamp Unit Replacement

The lamp used for the light source has its due life. The life of light source lamp used in the main unit is 2 000 hours. However, it may happen that the lamp becomes dead (will not light) by the time of 2 000 hours depending on the characteristics of individual lamps and working conditions (lamps may reduce their life affected by the times of lighting and the intervals between previous lighting and next lighting). Therefore, it is strongly recommended for the user to keep a spare bulb. If a lamp unit has not been replaced after 2 000 hours of operation have elapsed, the lamp will turn off automatically. when the operating time for all of the lamps reaches 2 000 hours or more, the power will turn off automatically approxmately 10 minutes after it is turned on, and the projector will switch to standby mode.
