The service technician is required to read and follow the “Safety Precautions” and “Important Safety Notice” in this service manual.
CAUTION
    Lithium Battery
    About lead free solder (PbF)
WARNING:
CAUTION : 
Any unauthorized changes or modifications to this equipment will void the users authority to operate.
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 soldering 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.
 
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
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 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.

Cautions when transporting
f
When transporting the projector, move the lens position to the home position and attach the lens cushion.
If lens optional model, move the lens position to the home position, remove the projection lens, and then attach
the lens hole cover.
f
When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts.
They may damage the internal components and result in malfunctions.
f
Do not transport the projector with the adjustable feet extended. 
Doing so may damage the adjustable feet.
Do not set up the projector in the following locations.
f
The projector is designed for indoor use only.
f
Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal
components or malfunction.
f
Location close to sea or where corrosive gas may occur: The projector may fall due to corrosion.
Also, it 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 lamp, or result in deformation of the outer case due to heat, which may cause malfunctions.
The operating environment temperature of the projector should be between 0 °C (32 °F) and 45 °C (113 °F) when
using it at elevations lower than 1 400 m (4 593') above sea level, and between 0 °C (32 °F) and 40 °C (104 °F) when
using it at high altitudes (between 1 400 m (4 593') and 2 700 m (8 858') above sea level).
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 lens surface causes damage
to the DLP chips.
f
Do not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
Note at the time of installation
f
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 that images be projected continuously for at least
30 minutes before the focus is adjusted.
f
Do not use the projector tilted to the right or left.
Using the projector at a vertical angle that exceeds ±15° may reduce product life or result in malfunction.
