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.
· 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.
Fig. 1
Table 1
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.

A blue-purple color mixture appears in the right of the screen. (When CEILING setting, appears it in the left of the screen.)
b.Increase CW INDEX setting value by 1, and record the value where the color mixture disappears. (The recorded value is
assumed to "A".)
c.Increase CW INDEX setting value from the default value (431) by 50, and set it to 481.
An orange color mixture appears in the right of the screen. (When CEILING setting, appears it in the left of the screen.)
d.Decrease CW INDEX setting value by 1, and record the value where the color mixture disappears. (The recorded value is
assumed to "B".)

6 Setting the Projector ID Number 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
1.Change the position of the operation mode selector switch to “Computer”.
2.Press the ID SET button, and within five seconds use the numeric (0 to 9) buttons to enter the 2-digit ID number set by the
projector.
3.Change the position of the operation mode selector switch to “Projector”.
However, if the ID ALL button is pressed, the projector can be controlled regardless of the ID number of the projector
(simultaneous control mode).
· 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 the ID SET button is pressed, the ID number goes back to the one set before pressing the ID SET button unless a
numeric button is pressed within five seconds after the ID SET button is 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 dry cells are replaced, set the same
ID number again.
· When setting the ID number, the numeric buttons entering of two digits is required even if the 1-digit ID number is set
on the projector side.
For example, setting remote control ID when ID number of the projector is "1": Press the numeric buttons of "0" and "1"
within five seconds after the ID SET button is pressed.
