Marantz PD4220V To avoid damage and prolong operating life, Plasma monitor cleaning procedure

To avoid damage and prolong operating life:

1.Use only with 120V 50/60Hz AC power supply. Continued operation at line voltages greater than 120 Volts AC will shorten the life of the unit, and might even cause a fire hazard.

2.Handle the unit carefully when installing it and do not drop.

3.Set the unit away from heat, excessive dust, and direct sunlight.

4.Protect the inside of the unit from liquids and small metal objects. In case of accident, unplug the power cord and have it serviced by an authorized Service Center.

5.Do not hit or scratch the panel surface as this causes flaws on the surface of the screen.

6.For correct installation and mounting it is strongly recommended to use a trained, authorized dealer.

7.As is the case with any phosphor-based display (like a CRT monitor, for example) light output will gradually decrease over the life of a Plasma Display Panel.

8.To avoid sulfurization it is strongly recommended not to place the unit in a dressing room in a public bath or hot spring bath.

Plasma monitor cleaning procedure:

1.Use a soft dry cloth to clean the front panel and bezel area. Never use solvents such as alcohol or thinner to clean these surfaces.

2.Clean plasma ventilation areas with a vacuum cleaner with a soft brush nozzle attachment.

3.To ensure proper ventilation, cleaning of the ventilation areas must be carried out monthly. More frequent cleaning may be necessary depending on the environment in which the plasma monitor is installed.

Recommendations to avoid or minimize phosphor burn-in:

Like all phosphor-based display devices and all other gas plasma displays, plasma monitors can be susceptible to phosphor burn under certain circumstances. Certain operating conditions, such as the continuous display of a static image over a prolonged period of time, can result in phosphor burn if proper precautions are not taken. To protect your investment in this plasma monitor, please adhere to the following guidelines and recommendations for minimizing the occurrence of image burn:

*Always enable and use your computer’s screen saver function during use with a computer input source.

*Display a moving image whenever possible.

*Change the position of the menu display from time to time.

*Always power down the monitor when you are finished using it.

If the plasma monitor is in long term use or continuous operation take the following measures to reduce the likelihood of phosphor burn:

*Lower the Brightness and Contrast levels as much as possible without impairing image readability.

*Display an image with many colors and color gradations (i.e. photographic or photo-realistic images).

*Create image content with minimal contrast between light and dark areas, for example white characters on black backgrounds. Use complementary or pastel color whenever possible.

*Avoid displaying images with few colors and distinct, sharply defined borders between colors.

* Note: Burn-in is not covered by the warranty.
