*2: HDMI signal of 480i and 576i is only supported by 27 MHz Dot clock signal.
*3:  Where marked "o" signals indicates in Plug and Play is compatible with EDID of projector . Unmarked signals in Plug and 
Play may also be compliant if input terminals are written in the format \
list. Where Plug and Play is unmarked and nothing is 
written in the format list, difficulties in projecting image may occur even when computer and projector appear to have same 
resolution.

Ceiling mount bracket safeguards
Installation work of the ceiling mount bracket should only be carried by a qualified technician. z
Even if it is during guaranteed period, the manufacturer is not responsible for any hazard or damage caused  z
by using a ceiling mount bracket which is not purchased from an authorized distributors, or environmental 
conditions.
Remove an unused ceiling mount bracket promptly. z
Ensure to use a torque driver and do not use an electrical screwdriver or an impact screwdriver. z
For details, see the work instruction manual packed together with the ceiling mount bracket. z
The model Nos. of the accessories and the parts sold separately are subj\
ect to change without notice. z
Make sure the screws on the ceiling mount kit cannot touch the metal parts materials (metallic lath, wire or  z
board) in the ceiling board. Otherwise it may result in fire hazard.
