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 QV261-HDSDI 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.
