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 remov-
ing 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
< RQ22K >
There are special components used in this equipment which are important for safety. These parts are marked by 7 in the schematic dia-
gram, 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 commercial environ-
ment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruc-
tion 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 shielded inter-
face cables when connecting to computer or peripheral devices. Also, any unauthorized changes or modifications to this equipment could void 
the user’s authority to operate this device.
Cautions when transporting
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
 When transporting the projector, remove the projection lens and attach the supplied lens hole cover beforehand.
    z Move the projection lens to the home position before removing the projection lens.
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 
damage 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”.
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.
    Upper limit of the operating environment temperature varies depending on the altitude above sea level.
     When using the projector at an altitude between 0 m (0') and 1 400 m (4 593') above sea level: 0 °C (32 °F) to 45 °C (113 
°F)
     When using the projector at an altitude between 1 400 m (4 593') and 4 200 m (13 780') above sea level: 0 °C (32 °F) to 40 
°C (104 °F)

PREFACE
< RQ22K >
r
 
Projection in all 360° direction is possible.
 
r
 
The geometric adjustment is disabled when projecting an image in simultaneous format.
     The geometric adjustment function cannot be used when the video signal in simultaneous format is input. When installing 
the projector, follow the instructions below so that distortion does not occur in the projected image.
 
f
 Use a flat screen.
 
f
 Install the projector so that the front side of the projector is parallel to the screen.
 
f
 Install the projector so that the image can be projected within the lens shift adjustment range.
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)
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.
