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-LCD15SB-AFHD-DT 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
