24) This reminder is provided to call the cable TV system installer's attention to Article 820-40 of the NEC that
provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to
the grounding system of the building, as close to the point of cable entry as practical.
25) Sudden high volume sound may cause hearing or speaker damage. When you use headphones, (if the unit is
equipped with a headphone jack) keep the volume at a moderate level. If you use headphones continuously with
high volume sound, it may cause hearing damage.
26) The mains plug is used as the disconnect and shall remain readily operable.
CONDENSATION
Moisture will form in the operating section of the unit if the unit is brought from cool surroundings into a warm room
or if the temperature of the room rises suddenly. When this happens, unit's performance will be impaired. To prevent
this, let the unit stand in its new surroundings for about an hour before switching it on, or make sure that the room
temperature rises gradually.
Condensation may also form during the summer if the unit is exposed to the breeze from an air conditioner. In such
cases, change the location of the unit.
HOW TO HANDLE THE LCD PANEL
• Do not press hard or jolt the LCD panel. It may cause the LCD panel glass to break and injury may occur.
• If the LCD panel is broken, make absolutely sure that you do not touch the liquid in the panel. This may cause skin
inflammation.
If the liquid gets in your mouth, immediately gargle and consult with your doctor. Also, if the liquid gets in your eyes
or touches your skin, consult with your doctor after rinsing for at least 15 minutes or longer in clean water.
Possible Adverse Effects on LCD Panel: If a fixed (non-moving) pattern remains on the LCD Panel for long periods of time,
the image can become permanently engrained in the LCD Panel and cause subtle but permanent ghost images. This
type of damage is NOT COVERED BY YOUR WARRANTY. Never leave your LCD Panel on for long periods of time while it is
displaying the following formats or images:
• Fixed Images, such as stock tickers, video game patterns, TV station logos, and websites.
• Special Formats that do not use the entire screen. For example, viewing letterbox style (16:9) media on a normal (4:3)
display (black bars at top and bottom of screen); or viewing normal style (4:3) media on a widescreen (16:9) display
(black bars on left and right sides of screen).
The following symptoms are not signs of malfunction but technical limitation. Therefore we disclaim any responsibility
for these symptoms.
• LCD Panels are manufactured using an extremely high level of precision technology, however sometimes parts of the
screen may be missing picture elements or have luminous spots.
• Do not install the LCD Panel near electronic equipment that produces electromagnetic waves. Some equipment placed
too near this unit may cause interference.
• Effect on infrared devices – There may be interference while using infrared devices such as infrared cordless
headphones.
