13 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....

About lead free solder PbF

This projector is using the RC.Board which applies lead free solder. The use of lead free solder is recommended from the standpoint of antipollution for the global environment in service. 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 C to 40 C higher. When servicing, use a high temperature soldering iron with temperature limitation function and set it to 370 10 C. * Be precautions about lead...
