Safety Instructions
The service technician is required to read and follow the “Safety Precautions” and “Important Safety Notice” in this service manual.
  
 WARNING
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 prod-
uct. 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.
 
 WARNING : Use UV Radiation eye and skin protection during servicing
CAUTION
  Precaution
   
 If using of this projector at high altitudes, “High Altitude” to “ON” for 1,000 to 3,000m.
   
(Refer to “PROJECTOR SETUP menu” in Operating Instructions.)
   
Failure to observe this may cause malfunctions. Never use this projector at an altitude of 3,000m or higher.
   
Using this projector at high altitude, consult your dealer or Authorized Service Center about preparations.
  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 com-
pletely, 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.
For US
There are special parts used in Panasonic Projectors which are important for safety. These parts are shaded on the schematic dia-
gram. 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.
IMPORTANT SAFETY NOTICE
WARNING:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC 
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruc-
tions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a 
particular installation.
If this equipment dose cause harmful interference to radio or television reception, which can be determined by turning the equipment
off and on, The user is encouraged to try to correct the interference by one or more of the following measures.
  - Reorient or relocate the receiving antenna.
  - Increase the separation between the equipment and receiver.
  - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
  - Consult the dealer or an experienced radio/TV technician for help.
CAUTION : Any unauthorized changes or modifications to this equipment will void the user’s authority to operate this 
device.

Safety precautions
<PT-FW430U/PT-FW430E/PT-FW430EA/PT-FX400U/PT-FX400E/PT-FX400EA>
1. Safety Precautions
  1.1. General Guidelines
  1.2. Leakage Current Check
1. Prepare the measuring circuit as shown in Fig.1.
    Be sure to use a voltmeter having the performance described in Table 1.
2. Assemble the circuit as shown in Fig. 2. Plug the power cord in a power outlet.
3. Connect M1 to T1 according to Fig. 2 and measure the voltage.
4. Change the connection of M1 from T1 to T2 and measure the voltage again.
5. The voltmeter must read 0.375 V or lower in both of steps 3 and 4.  This means that the current must be 0.75mA or less.
6. If the reading is out of the above standard, the projector must be repaired and rechecked before returning to the customer
    because of a possibility of an electric shock.
- For continued safety, no modification of any circuit must be attempted.
- Unplug the power cord from the power outlet before disassembling this projector.
- Use correctly the supplied power cord and must ground it.
- It is advisable to use an isolation transformer in the AC power line before the service.
- Be careful not to touch the rotation part (cooling fan, etc.) of this projector when you service with the upper
  case removed and the power supply turned ON.
- Observe the original lead dress during the service. If a short circuit is found, replace all the parts overheated
  or damaged by the short circuit.
- After the service, all the protective devices such as insulation barriers, insulation papers, shields, and isolation
  R-C combinations must be properly installed.
- After the service, check the leakage current to prevent the customer from getting an electric shock.

  1.3. UV Precaution and UHM Lamp Precautions
- Be sure to unplug the power cord from the power outlet when replacing the lamp.
- Because the lamp reaches a very high temperature during its operation, wait until it cools completely when replacing
  the Lamp Unit.
- The lamp emits small amounts of UV-radiation, avoid direct-eye contact with the light.
- The lamp unit has high internal pressure. If improperly handled, explosion might result.
- Because the high pressure lamp involves a risk of failure, never touch the lamp wire lead during the service.
