PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the projector have special safety related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement compo- nents rated for higher voltage, etc.
Page 5: Safety Precautions
SAFETY PRECAUTIONS North america NOTICE: Observe all cautions and safety related notes located inside the cabinet and on the chassis. Warning . Operation of this projector outside the cabinet or with the cover removed presents a shock hazard from the projector power supplies.
Page 6: Precautions For Resoldering
PRECAUTIONS FOR RESOLDERING Lead-free solder is handled in a different way from eutectic solder. See below for details. How to distinguish circuit boards using lead-free solder from those using eutectic solder Circuit boards using lead-free solder A mark of PCA or LFS (for limited marking space) is printed near the board assembly number on Solder, Joints, the component side.
