Transporting the Projector
The projector contains many glass and precision parts. When 
hand-carrying the projector, use a carrying case (included with the 
EX3200/EX5200/EX7200 only).
Follow these guidelines to prevent damage when transporting it: 
■Close the A/V Mute slide (lens cover).
■If a USB device is connected, remove it from the projector.
■Return the projector feet to their stored (highest) positions.
■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 place it in a 
hard-shell shipping case, then pack it in a firm box with 
cushioning around the case.
