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, remove the projection lens before attaching the dust sponge.
Otherwise dust will accumulate inside and may cause malfunctions.
f
Transport the projector with 2 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 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
Do not set up the projector outdoors. 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, 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
 lamp, or result in deformation of the outer case due to heat, which may cause malfunctions.
f
 
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 should be 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).
If you use the smoke cut filter, the operating environment temperature should be between 0 °C (32 °F) and
35 °C (95 °F). However, it cannot be used at high altitudes.
If you use the Replacement lamp unit (for portrait mode), the operating environment temperature should be 
between 0 °C (32 °F) and 40 °C (104 °F)  when using it at elevations lower than 1 400 m (4 593') above sea level, 
 
and should be between 0 °C (32 °F) and 35 °C (95 °F) when using it at high altitudes (between 1 400 m (4 593') 
and 2 700 m (8 858') above sea level).
If you use the Replacement lamp unit (for portrait mode) together with the smoke cut filter, the operating environment
temperature should be between 0 °C (32 °F) and 30 °C (86 °F). (Only for PT ‑DZ21K2, PT‑DS20K2, PT‑DW17K2)
f
Do not install the projector at elevations of 2 700 m (8 858') or higher 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 projection lens surface causes
damage to the DLP chips.
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.
Cautions when installing
f
After attaching the projection lens, be sure to attach the lens mount cover.
Otherwise dust will accumulate inside and may cause malfunctions.
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 the life of components or result in malfunctions.
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.
