Installation
Securing the lens unit with the fall prevention wire
• If the projector is going to be suspended from a ceiling or another high place,
secure the lens unit using the fall prevention wire (sold separately). If the lens
unit is not secured, it may fall down if it comes lose.
REQUIRED
On use
Do not use on networks subject to overvoltage.
• Connect the projector's Ethernet/HDBaseT port and LAN port to a network
for which there is no risk of overvoltage being applied.
Overvoltage applied to the Ethernet/HDBaseT or LAN port could result in
PROHIBITED
electric shock.
Lens shift, focus and zoom operations
• When shifting the lens or adjusting the focus or zoom, do so from either
behind or the side of the projector. If adjustments are performed from the
front, your eyes could be exposed to strong light and get injured.
REQUIRED
• Keep your hands away from the lens area when performing the lens shift op-
eration. If not, your fingers could get caught in the gap between the cabinet
and the lens.

About the vents
• Do not obstruct the projector's vents. Also, do not place such soft objects as
paper or cloths underneath the projector. Doing so could lead to fire.
Leave sufficient space between the place where the projector is installed and
