Maintenance
■Screen Cleaning
Periodically clean the screen surface using ammonia-free cleaning wipes (Marshall Part No. V-HWP-K). A clean micro-fiber cloth
can also be used using only non-abrasive and ammonia-free cleaning agents. Do not use paper towels. Paper towel fibers are
coarse and may scratch the surface of the polycarbonate faceplate or leave streaks on the surface. Antistatic and fingerprint
resistant cleaning agents are recommended. Do not apply excessive pressure to the screen to avoid damaging the LCD.
■Faceplate Dusting
Dust the unit with a soft, damp cloth or chamois. Dry or abrasive cloths may cause electrostatic charge on the surface, attracting
dust particles. Neutralize static electricity effects by using the recommended cleaning and polishing practice.
Warranty
Marshall Electronics warranties to the first consumer that this V-MD151 LCD monitor 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 first consumer 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 the consumer. This warranty does not apply to the product exterior or
cosmetics. Misuse, abnormal handling, alterations or modifications in design or construction void this warranty. 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 reserves the option to refuse service for display pixel failure if deemed unobtrusive to effective use of the monitor by
our technicians. No sales personnel of the seller or 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
described above. Due to constant effort to improve products and product features, specifications may change without notice.

Installation and Initial Setup
■Unpacking
Carefully unpack the V-MD151 monitor and verify that the following items are included:
• V-MD151 Monitor
• V-PS12V-5A-XLR Power Supply
• Operating Instructions
Inspect the unit for any physical damage that may have occurred during shipping. Should there be any damage, immediately
contact Marshall Electronics at [phone]. If you are not located within the continental United States, call +1 (310) 333-
0606.
■Installation
The V-MD151 can be mounted in any standard EIA 19” equipment rack. The attached rack ears can be angled to provide the user
control over the viewing angle. Adequate ventilation is required when installed to prevent possible damage to the monitor’s
internal components. Please see the Dimensions section for more information.
A VESA standard 75mm hole pattern also allows custom mounting installations. Alternately, the V-MD151 can be used in a
desktop configuration with optional stand. Please contact Marshall Electronics for more information.
Warning: Please use only the square type VESA mount (which fits inside the VESA Screw Length WARNING
silkscreen) with the 75mm hole pattern in order to avoid obstructing Module Slot 2.
Please contact Marshall Electronics or visit www.LCDRACKS.com for further information.
■Connections, Power-On and Initial Setup
Plug the power supply into an AC power source (100-240 V @ 50/60 Hz). Attach the Power connector to the back of the monitor.
Connect the required cables for video signal input and output. (Power must be applied to the V-MD151 for the active loop-
though output to be activated.) The monitor defaults to ‘ON’ when power is supplied. Video will automatically be detected and
displayed on the screen.
