Canon WUX500ST Quick Start Manual page 73

Cause
Video is blurred.
Motion blur reduction is
not available.
The sharpness setting is
not available.
■ You Cannot Project an Image Appropriately
Cause
The projected image is
inverted in the vertical or
horizontal direction.
The dot clock of the input
signal is higher than 162
MHz with a BNC cable.
A computer cable is
used in which some pins
are not connected.
■ The Projector Power Turns Off
Cause
The air intake or exhaust
vent is blocked.
The air filter is dirty.
The lamp has ruptured
(or there is a lamp
malfunction).
The operating
temperature is
inappropriate.
Countermeasure
Activate motion blur reduction.
Motion blur reduction is not available in projection
using USB flash drives or networked multi-projection.
Sharpness cannot be adjusted during split-screen
display.
Countermeasure
The ceiling mounted / rear projection setting is
incorrect. Check the [Image flip H/V] setting in the
[Install settings] menu.
Set the signal dot clock to 162 MHz or less on your
computer.
Use a computer cable in which all pins are
connected.
Countermeasure
Check whether the air intake or exhaust vent is
blocked. If the air intake or exhaust vent is blocked,
the temperature inside the projector will increase and
the power is automatically turned off to protect the
projector. (The [WARNING] indicator and [TEMP]
indicator are lit.) Wait until the projector temperature
drops, then make sure that the intake and exhaust
vents are not blocked and turn on the projector. (P30,
P40)
Check whether the air filter is clogged with dust.
If the air filter is clogged, clean or replace the air filter.
(P62, P64)
If the lamp has ruptured, follow the instructions in
"Note the following precautions when replacing
lamps that stop working. Failure to do so could result
in personal injury." (P17).
Check whether the operating temperature is between
0°C (32°F) and 40°C (104°F). (P20)
Projector settings must be adjusted when using the
projector at altitudes of 2,300 m (7,545.8') or higher.
In the [Install settings] menu, set [Fan mode] under
[Professional settings] to [High altitude].
