About lead free solder (PbF)
Any unauthorized changes or modifications to this equipment will void the users authority to operate.
Cautions when transporting
Do not set up the projector in the following locations.
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.
Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal
components or malfunction.
Do not use the device under the condition with the intake/exhaust ports of the device blocked or intake/exhaust air interfered.
The temperature around the device should be within the following range.
- When using at a location lower than 1 400 m (4 593') above sea level: 0 °C (32 °F) - 40 °C (104 °F)
- When using the device between 1 400 m (4 593') and 2 700 m (8 858') above sea level: 0 °C (32 °F) - 35 °C (95 °F).
Near high-voltage power lines or near motors: Doing so may interfere with the operation of this device.
This service information is designed for experienced repair technicians only and is not designed for use by the general public.
It dose not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to service a product.
Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service
or repair the product or products dealt with in this service information by anyone else could result in serious injury or death.
There are special parts used in Panasonic Multi Window Processor which are important for safety. These parts are shaded on the
schematic diagram. 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 PANASONIC SOLUTIONS COMPANY.
This is a class A product. In a domestic environment this product may cause radio interference in which case the user
may be required to take adequate measures.
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.
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.
