Terminology

This section provides simple explanations for the terminology used within the manual, items for which explanations are not available, and other complex processes.

A/V Mute

Temporarily erases the image and sound. The sound and image can be muted

 

by pressing the [A/V Mute] button on the projector. Press the [A/V Mute]

 

button once again or adjust the volume or display the menu to cancel the mute

 

mode.

D output port

The output port for digital tuners that support the new digital broadcasts

 

within Japan.

SVGA

IBM PC/AT compatible (DOS/V equipment) signals with 800 horizontal pix-

 

els and 600 vertical pixels.

SXGA

IBM PC/AT compatible (DOS/V equipment) signals with 1,280 horizontal

 

pixels and 1,024 vertical pixels.

Sync(synchronization)

Outputs computer signals at a pre-determined frequency. The image will not

 

be projected clearly unless this frequency is aligned with the frequency of the

 

projector. Aligning the signal phasing is known as synchronization. Projected

 

images will be subject to distrubance, blurring and horizontal noise if not syn-

 

chronized.

VGA

IBM PC/AT compatible (DOS/V equipment) signals with 640 horizontal pix-

 

els and 480 vertical pixels.

XGA

IBM PC/AT compatible (DOS/V equipment) signals with 1,024 horizontal

 

pixels and 768 vertical pixels.

USB

An abbreviation for Universal Serial Bus. This is an interface for connecting

 

comparitively low frequency equipment to the computer.

UXGA

IBM PC/AT compatible (DOS/V equipment) signals with 1,600 horizontal

 

pixels and 1,200 vertical pixels.

Color temperature

The temperature of the subject that emits light. A blue hue is attained when

 

the color temperature is high, and a red hue is attained when the color temper-

 

ature is low.

Color differential signal

Video equipment transmits signals through three cables as Red-Bright (R-Y),

 

Yellow-Bright (Y) and Blue-Bright (B-Y). This enables the composite signals

 

(the red, green and blue signals and their brightness signals are transmitted

 

along one cable) to be projected more clearly.

Operating system

The software necessary to operate the computer. The EMP Link V supplied

 

with the projector operates the computers with the use of the Windows 95

 

(Japanese version) operating system, the Windows 98 (Japanese version) oper-

 

ating system, the Windows NT 4.0 (Japanese version) operating system, the

 

Windows 2000 (Japanese version) operating system, and the Macintosh Kanji

 

Talk 7.5.5 or higher operating systems.

Cool-down

A lamp cooling procedure continues to operate even after the power supply

 

has been switched off and the lamp extinguished. The cooling fan will begin

 

to operate when the lamp is entinguished, and button operations will no

 

longer be possible. This period is known as the cooling down period. The

 

amount of time required for the cooling down procedure will differ in accor-

 

dance with the surrounding temperature.

Epson EMP-715/505 manual Terminology

EMP-715/505 specifications

The Epson EMP-715 and EMP-505 are versatile projectors that exemplify the best of Epson's innovation in the field of visual display technology. Designed for both business and educational environments, these models combine high performance with user-friendly features.

At the heart of the EMP-715 and EMP-505 is Epson’s proprietary 3LCD technology, which ensures superior color reproduction and brightness. This technology utilizes three separate liquid crystal panels—one for each primary color: red, green, and blue. The result is vibrant, true-to-life images that stand out in any lighting condition. With a brightness of up to 3500 lumens, both models excel in delivering clear presentations in rooms with varied ambient light.

Resolution is key in ensuring clarity in visual presentations, and both projectors provide a native resolution of XGA (1024 x 768). This resolution is ideal for detailed graphics, presentations, and video content, allowing users to display text and images with impressive sharpness. Additionally, they support various resolutions for maximum versatility, adapting to different content and formats seamlessly.

Portability is another significant feature of the EMP-715 and EMP-505. Weighing approximately 2.5 kg, they are lightweight and compact, making them easy to transport between locations. This portability is complemented by a quick-start function, allowing users to set up presentations with minimal downtime.

Furthermore, connectivity options are robust with multiple input ports including HDMI, VGA, and USB ports, ensuring compatibility with a wide range of devices, from laptops and desktops to USB drives and document cameras. These features enhance the projectors' versatility, making them suitable for various presentation scenarios.

The EMP-715 and EMP-505 also include advanced features such as keystone correction, which allows users to easily adjust and correct image distortion when projecting from an angle. This makes it easier to achieve a perfect image from any position in a room.

For enhanced operation, these projectors come equipped with a user-friendly interface and remote control, ensuring ease of use even during complex presentations. The long lamp life of up to 5000 hours in Eco mode offers a cost-effective solution for users, reducing the frequency of replacements and maintenance.

In a nutshell, the Epson EMP-715 and EMP-505 projectors stand out in the market due to their combination of high brightness, excellent resolution, advanced connectivity, and portability. They are perfect for anyone needing a reliable, efficient projection solution in professional and educational settings. With Epson’s commitment to quality and innovation, these projectors continue to be trusted tools for effective communication and presentations.
