Marshall Electronics warranties to the first consumer, that this V-R841P-AFHD 8.4-inch LCD monitor mounted monitor set will, under
normal use, be free from defects in workmanship and materials, when received in its original container, for a period of one year from the
purchase date.

This warranty is extended to the purchasing end user only and proof of purchase is necessary to honor the warranty. If there is no proof
of purchase provided with a warranty claim, Marshall Electronics reserves the right not to honor the warranty set forth above. Therefore,
labor and parts may be charged to you.

This warranty does not apply to product exterior and cosmetics. Misuse, abnormal service or handling, improper alterations or modifications
in design or construction, voids this warranty. No sales personnel of the seller, nor any other person is authorized to make any warranties
other than those described above, or to extend the duration of any warranties on behalf of Marshall Electronics, beyond the time period

An extra note about LCD displays: It is considered normal for a minimal amount of pixels, not to exceed three, to fail on the periphery of
the display active viewing area. Marshall Electronics has the option to reserve service for display pixel failure if deemed unobtrusive to
effective use of the monitor by our technicians.

Due to constant effort to improve products and product features, specifications may change without notice.

Safe Area Overlay

A shaded border is placed onto the edge of image indicating a user selected area deemed to be safe for graphic and other
image placement. Safe Area overlays are available that indicate 80%, 88%, 90%, and 93% of the displayed image. The safe
area displays for the selected screen aspect.

Center Mark

A cross hair cursor is placed on the middle of the screen. The lines of the cross hair consist of a center white element that is
4 pixels wide, surrounded by a black border on each side that is 2 pixels wide. Use of black and white for the Center Mark
function allows the viewer to see screen center in all ranges of color for the screen image.

defi nition signals. SDI signals will display all data input with ancillary data appearing to the right of the image.

Pixel to Pixel Function

As the native LCD displays of the V-R842P-AFHD are 1080 pixels wide by 768 pixels high, it is necessary to change the
size of the image to fi ll the whole screen. Pixel to Pixel mode bypasses the enlargement/shrink of this scaling function and
displays the native incoming format.
For 525-NTSC/480P based images, pixel to pixel will appear as a 480x640 (4:3 aspect) or 480x720 (16:9 aspect).
For 625-PAL/576P based images, pixel to pixel will appear as a 576x640 (4:3 aspect) or 576x720 (16:9 aspect).
For 1080 line HD based images, pixel to pixel will appear as cropped 768x1024 (4:3 aspect) starting from the center of the image.
For 720 line HD based images, pixel to pixel will appear as a 720x1024 (4:3 aspect) with 128 pixels from the left and 128 pixels from
the right cropped.

Color Temperature (Temp Button)

The V-R841P-AFHD has four color temperature settings that adjust the color balance of the screen for varying ambient conditions.
D-55 (5500K) - Simulates indoor incandescent light conditions.
D-65 (6500K) - Standard setting recommended by SMPTE and EBU. Simulates normal daylight conditions.
D-75 (7500K) - Simulates bright daylight conditions.
DEFAULT- 7900K

Blue Gun & Mono (Monochrome Black & White)

Use to adjust SMPTE or split fi eld color bars.

1. Allow monitor to warm up for 5-10 minutes minimum.
Adjustments will not be accurate on a cold monitor.

2. Display SMPTE color bars on monitor. Turn on Mono

3. Find the PLUGE (superblack, black, and gray bars) at the lower right of the pattern.
Adjust BRIGHTNESS control until there is no difference visible between the
superblack and black bars, but a difference is visible between the black and gray bars.

4. Adjust CONTRAST control to achieve a balanced gray scale across top bars.

5.Turn off Mono then turn on BLUE GUN

6. Turn up CHROMA (color level) control until the two outermost bars (white and blue appear to match in brightness.

7. NTSC Only - Adjust COLOR PHASE (tint or hue) control until the third bar from the left (cyan) and the third bar from the right
(magenta) appear to match in brightness.

Frame Marker (Only active in 16:9 display mode)

Frame Aspect Markers are used to frame the image for an additional screen format when 16:9 display is enabled.
For example 4:3 marker is often used for HD broadcasts that are also down converted and cropped for SD transmission.
Frame markers are available for 4:3, 15:9, 14:9, 13:9, 1.85:1, 2.35:1 and 2.37:1 screen aspects.
