PREFACE
< RZ120 >
CAUTION
  About lead free solder (PbF)
 
 
This projector is using the P.C.Board which applies lead free solder.
 
 
Use lead free solder in servicing from the standpoint of antipollution for the global environment.
  Notes:
 
 
•  Lead free solder: Sn-Ag-Cu (tin, silver and copper) has a higher melting point (approx. 217°C) than standard solder Typically the melting point is 30~40 
°C higher. When servicing, use a high temperature soldering iron with temperature limitation function and set it to 370 ± 10 °C.
 
 
•  Be precautious about lead free solder. Sn-Ag-Cu (tin, silver and copper) will tend to splash when heated too high (approx. 600°C or higher).
• Use lead free solder for the P.C.Board (specified on it as “PbF”) which uses lead free solder. (When you unavoidably use lead solder, use lead solder
after removing lead free solder. Or be sure to heat the lead free solder until it melts completely, before applying lead solder.)
• After solder to double layered P.C Boards, check the component side for excess solder which may flow onto the opposite side.
About the identification of the lead free solder P.C.Board.
For the P.C.Board which applies lead free solder, the symbol as shown in the figure below is printed or stamped on the surface or the back of P.C.Board.

PREFACE
< RZ120 >
There are special components used in this equipment which are important for safety. These parts are marked by 7 in the schematic 
diagram, circuit board diagrams, exploded views and replacement parts list. It is essential that these critical parts should be replaced 
with manufacturer’s specified parts to prevent shock, fire, or other hazards. Do not modify the original design without permission of 
manufacturer.
IMPORTANT SAFETY NOTICE
Caution:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. 
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commer-
cial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance 
with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area 
is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
FCC Warning:
To assure continued compliance, follow the attached installation instructions. This includes using the provided power cord and shield-
ed interface cables when connecting to computer or peripheral devices. Also, any unauthorized changes or modifications to this equip-
ment could void the user’s authority to operate this device.
Intended use of the product
f
  The purpose of the projector is to project a video signal from imaging equipment or a computer on a screen or other surface 
as a still image or moving image.
Cautions when transporting
f
  When transporting the projector, move the lens position to the home position and attach the lens protection material when 
transporting. Lens optional model, move the lens position to the home position, remove the projection lens, and attach the 
lens hole cover when transporting.
f
 Lens home position moving procedure.
   1)  Press the [DEFAULT] button on the remote control while
       displaying the lens shift adjustment screen.
   2) Press [q] [w] to select [OK], and press the [ENTER] button.
f
  Transport the projector with two or more people. Failure to do so may drop the projector, which may result in damage or 
deformation of the projector, or injury.
f
  When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impact. Failure to do so 
may cause a failure due to the damaged internal components.
f
 Do not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.
Cautions when installing
r
 
Do not set up the projector outdoors.
    The projector is designed for indoor use only.
r
 
Do not set up the projector in the following locations.
  f   Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal compo-
nents or malfunction.
  f  Location close to sea or where corrosive gas may occur: The projector may fall due to corrosion. Also, failure to do so 
may shorten the life of the components and result in malfunctions.
  f  Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare cases due 
to the heated air from the air exhaust port or the hot or cooled air. Make sure that the exhaust from the projector or other 
equipment, or the air from the air conditioner does not blow toward the front of the projector.
  f  Places with sharp temperature fluctuations such as near lights (studio lamps): Doing so may shorten the life of the light 
source, or result in deformation of the projector due to heat, which may cause malfunctions.
     Follow the operating environment temperature of the projector.
  f Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
  f  Places where there is high-power laser equipment: Directing a laser beam onto the projection lens surface causes dam-
age to the DLP chips.
r
 
The projector may not work properly due to strong radio wave from the broadcast station or the radio.
     If there is any facility or equipment which outputs strong radio waves near the installation location, install the projector at a 
location sufficiently far from the source of the radio waves. Or, wrap the LAN cable connected to the <DIGITAL LINK/LAN> 
terminal using a piece of metal foil or a metal pipe which is grounded at both ends.
r
 
Focus adjustment
     The high clarity 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 to perform the focus adjustment after 30 minutes have elapsed 
with the focus test pattern displayed. For details of the test pattern, refer to “[TEST PATTERN] menu”.

PREFACE
< RZ120 >
r
 
Do not install the projector at an altitude of 4 200 m (13 780') or higher above sea level.
r
 
Do not use the projector in a location that the ambient temperature exceeds 45 °C (113 °F).
     Using the projector in a location that the altitude is too high or the ambient temperature is too high may reduce the life of the 
components or result in malfunctions.
r
 
Projection in all 360° direction is possible.
r
 
Cautions when setting up the projector.
  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  When installing the projector with a method other than the floor installation using the adjustable feet, top placed on the 
floor, or the ceiling installation with the Ceiling Mount Bracket, use the five screw holes for ceiling mount to fix the projec-
tor to the mount.
    (Screw diameter: M6, tapping depth inside the projector: 12 mm (15/32"), torque: 4 ± 0.5 N·m)
  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 ac-
cumulate when the ventilation is not enough, triggering the protection circuit of the projector.

Usable outlet
This projector supports AC 100 V to AC 240 V as the power supply. A grounded outlet supporting 15 A is required 
with either voltage.
The shape of the usable outlet differs depending on the power supply. Following illustrations are examples.

Attention
 
f
Use the supplied power cord and ground at the outlet.
 
f
Use the power cord matching the used power supply voltage and outlet shape.
