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-MD503 or V-MD434 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

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
