LG HU80KG Owner's Manual page 27

• The projector is manufactured
using high-precision technology.
You may, however, see tiny
black dots and/or bright colored
dots (red, blue or green) that
continuously appear on the
projector screen. This is a normal
result of the manufacturing
process and does not indicate a
malfunction.
• The remote control may not work
in an environment where a lamp
equipped with electronic ballasts
or a three-wavelength fluorescent
lamp is installed. Replace the lamp
with an international standard lamp
for the remote control to work
normally.
• To install to the ceiling, attach
the ceiling-type bracket to the
projector with M4 x 8 mm screws.
•
Do not overtighten the screws. It
may damage the case, causing the
projector to fall and cause a serious
injury. (Recommended Torque: 5~8
kgf·cm)
•
Please be sure that the projector's
aperture (lens and mirror) is not
blocked by a person or any objects.
