9. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider
than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong is
provided for your safety. When the provided plug does not fit into your outlet, consult an electrician for the replacement of
the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles and the point
where they exit from the apparatus.

11. Only use the attachments/accessories specified by the manufacturer.

12. Use only with a cart, stand, tripod, bracket or table specified by the manufacturer or sold with the apparatus.
When a cart is used, use caution when moving the cart/apparatus to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in
any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

15. The +12V trigger only outputs 12Vdc signal for triggering. Do not connect to any other power input or output. This could
cause damage to this unit.

16. Keep the packing material in case the equipment should ever need to be shipped.

17. The lamp becomes extremely hot during operation. Allow the projector to cool down for approximately 45 minutes prior to
removing the lamp assembly for replacement.

18. Do not operate lamps beyond the rated lamp life. Excessive operation of lamps beyond rated life could cause them to
explode in rare occasions.

2 Q-750i Series Installation/Operation Manual

Introduction

Integrating Runco's award-winning controller/processor technology for flawless images
from any source, the Q-750i sets new standards in projection with Runco's
game-changing InfiniLight™ LED lampless technology, Personal Color Equalizer and
Runco SmartColor.

Runco's revolutionary QuantumColor™ projectors pair energy-saving LED technology
with proprietary Runco engineering to create unsurpassed performance and unrivaled
customization. The Runco QuantumColor Q-750i maximizes the benefits of Runco's new
InfiniLight™ lampless LED illumination technology to provide an infinite light source that
creates an energy-efficient projector with the widest color gamut ever available in home
theater projection.

But simply creating a projector platform with lampless technology and the largest color
gamut isn't enough. Harnessing its incredible color options, Runco introduces its
revolutionary new Personal Color Equalizer™, which allows color adjustment that includes
those exactly defined by the cinematographer and the color preferences of each individual
viewer for each source. Proprietary Runco Smart Color (RSC™) provides a hue
compensation curve and gamut mapping that allows for lifelike, accurate flesh tones while
increasing color saturation, without sacrificing the purity of other colors.

In addition to Runco's proprietary InfiniLight, Personal Color Equalizer and Runco Smart
Color, Runco the Q-750i can also be paired with Runco’s award-winning CineWide™ and
CineWide with AutoScope™ technology. CineWide provides uncompromised widescreen
reproduction of movies originally filmed in the CinemaScope™ 2:35:1 format. It maintains
constant vertical height on the screen just as in a movie theater. When a viewer transitions
from 1.78:1 (16:9) program material to superwide 2.35:1, the image simply gets wider
while full screen height is maintained, eliminating useless black bars on the top and
bottom of the screen.

Runco CineWide is achieved through Runco's ingenious combination of software,
electronics and precision anamorphic optics. With Runco CineWide, the projection
system is able to use the full pixel array, thereby producing a 2.35:1 image with enhanced
resolution and increased brightness. No resolution or image area is lost to those black
bars that contain no picture information. CineWide with AutoScope provides a motorized,
remote-controlled anamorphic lens mechanism.

3. Installation

To install batteries in the remote control:

1. Slide the battery compartment cover in
the direction of the arrow to remove it.

2. Install two AAA batteries with the
correct polarity.

3. Replace the cover.

Y

• Do not mix an old battery with a new one or different types of batteries.

• If you will not use the remote control for a long time, remove the batteries to avoid

damage from battery leakage.

• Make sure that there is nothing obstructing the infrared beam between the remote

control and the IR receiver on the projector.

• If the effective range of the remote control decreases, or it stops working, replace the

batteries with new ones.

• The remote control may fail to operate if the infrared remote sensor is exposed to bright

sunlight or fluorescent lighting.

• Ambient conditions may possibly impede the operation of the remote control. If this

happens, point the remote control at the projector, and repeat the operation.

Throw Distance Throw distance is the distance measured from the front of the projector to the screen.

➤

This is an important calculation in any projector installation as it determines whether or not
you have enough room to install your projector with a desired screen size and if your
image will be the right size for your screen.

You can quickly estimate the throw distance by taking the width of the screen and
multiplying it by the lens throw ratio; see
roughly how far back the projector should be positioned from the screen in order to
project a focused image large enough to fill the screen.

Estimating Throw Distance

Throw Distance (TD) = Screen Width (w) x Lens Throw Ratio
