LCD Display panel information
Important Information Regarding Use of Video Games, Computers, Captions or Other Fixed Image Displays.
The extended use of fixed image program material can cause a permanent "shadow image" on the LCD panel.
This background image is viewable on normal programs in the form of a stationary fixed image. This type of irreversible
LCD panel deterioration can be limited by observing the following steps:
A. Reduce the brightness/contrast setting to a minimum viewing level.
B. Do not display the fixed image for extended periods of time.
C. Turn the power off when not in actual use.
Note:
The marking or retained image on the LCD panel resulting from fixed image use is not an operating defect and as such
is not covered by Warranty. This product is not designed to display fixed image patterns for extended periods of time.
