Projection in all 360° direction is possible.
 
Cautions when setting up the projector
f
  Install the projector in a place or with a mount that can sufficiently tolerate the weight. The position of the projected image 
may shift if the strength is not sufficient.
f
  Use the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other purposes 
may damage the projector.
f
  The adjustable feet can be removed if not needed in the installation. However, do not use the screw holes where the ad-
justable feet were removed to fix the projector to a mount.
    Also, do not attach any screws not instructed in the operating instructions of the optional accessories into the screw holes 
where the adjustable feet are removed. Doing so may damage the projector.
f
  When using the projector in any method other than the floor installation using the adjustable feet or ceiling mounting instal-
lation using the Ceiling Mount Bracket, remove the four adjustable feet and use the six screw holes to fix the projector to a 
mount.
f
  Use a torque screwdriver or Allen torque wrench to tighten the fixing screws to their specified tightening torques.
   Do not use electric screwdrivers or impact screwdrivers.
   (Screw diameter: M6, tapping depth inside the projector: 27 mm (1-1/16"), screw tightening torque: 4 ± 0.5 N·m)

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.
