							68Maintaining and Transporting the Projector
Transporting the Projector
The projector contains many glass and precision parts. If you need to 
transport it, follow these packing guidelines to prevent damage
to the projector:

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.

When transporting the projector a long distance, first put it in a 
carrying case (such as an optional EPSON case), then pack it in a 
firm box, using cushioning around the case.

If you want to store the remote control inside the projector’s 
carrying case, be sure to turn it off using the switch on its side. 
This prevents the batteries from discharging if something presses 
against one of the buttons.

When you are hand-carrying the projector, use the carrying 
handle.

EPSON shall not be liable 
for any damages incurred 
during transportation.
