 Dust Filter Reminder Message:  z
 
 
 
 
 
 
This message displays when the projector reached the timer set in 
the [Filter Reminder (Hour)]. In this case, please clean the air filters or 
replace them.
54
 Lamp Warning Message:  z
 
The lamp has reached its end of life, please replace it as soon as 
possible.
57
 Fan Locked Warning Message:  z
 
 
This shows the fan has stopped during projection and the power will be 
shut off soon. Unplug the power cord from the outlet and contact your 
dealer for details.53
 Temperature Fail Message :   z
 
 
The internal temperature is too high and the power will be shut off soon, 
please confirm the display items.
Attention
Please contact your dealer if the projector still can not be operated no\
rmally after following the instructions above.  z
Note
The  operation may not optimize the image position or the resolution, depending on the input signal format or  z

*1: “i” added to the resolution value indicates an interlaced signal.
*2: HDMI signal of 480i and 576i is only supported by 27MHz 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.
Note
The number of display dots is 1 024 x 768 for PT-TX301RE and 1 280 x 800 for PT-TW331RE.  z
A signal with a different resolution will be projected after converting the resolution to match the projector display.
When interlaced signals are connected, flicker may occur on the projected image. z
Even the above signals exist, some image signals that recorded in special method may not be displayed. z
The  operation may not optimize the image position or the resolution, depending on the input signal format or  z
the image contents. In this case, switch to a different image and execute  again.
When the detected signal is out of display range under PC source, the "Out of display range" message will display on the  z
top left corner of the image.
