r
Mount the projector to the track system which is installed in the horizontal ceiling or
beam and can withstand the weight of the projector .
Mounting the projector to the following track system will result in fire, electric shocks, or falling of the projecto .
f
Track system that is installed in the wall surface
f
Track system that is installed in the sloping ceiling or beam
f
Track system that cannot withstand the load
f
Track system that is installed on the floo
Cannot be installed
r
Focus adjustment
The projection lens is thermally affected by the light from the light source, making the focus unstable in the period
just after switching on the power. It is recommended that images be projected continuously for at least 30 minutes
before the focus is adjusted.
r
Cautions when setting up the projector
f
Do not block the ventilation ports (intake and exhaust) of the projector.
f
Prevent hot and cool air from the air conditioning system to blow directly to the ventilation ports (intake and
exhaust) of the projector.
f
Do not install the projector in a confined space.
When installing the projector in a confined space, provide air conditioning or ventilation separately. Exhaust heat
may accumulate when the ventilation is not enough, triggering the protection circuit of the projector.

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 combi-
nations 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.
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 0.75mA 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.
