Transporting the Projector
The projector contains many glass parts and precision parts. If you 
need to transport it, please follow these packing guidelines to prevent 
damaging the projector: p
When shipping the projector for repairs, use the original 
packaging material if possible. If you do not have the original 
packaging, use equivalent materials, placing plenty of cushioning 
around the projector.
p
When transporting the projector for business use, first put the 
projector in a hard-shell carrying case (such as an optional EPSON 
accessory case), then pack it in a firm box, using cushioning 
around the case. 
p
When you are hand-carrying the projector, be sure to store it in a 
carrying case (such as the optional cases offered by EPSON).
Note: EPSON shall not be liable for any damages incurred during 
transportation.
