The fixed image may yy become permanently imprinted on the screen. Use a screen saver when possible. There may be interference relating to resolution, vertical pattern, contrast or brightness in PC mode. yy Change the PC mode to another resolution or change the refresh rate to another rate or adjust the brightness and contrast on the menu until the picture is clear. If the refresh rate of the PC graphic card can not be changed, change the PC graphic card or consult the manufacturer of the PC graphic card. The synchronization input waveform for Horizontal and Vertical frequencies are separate. yy Connect the signal cable from the RGB output port of the PC to the RGB (PC) port of the TV or the yy signal cable from the HDMI output port of the PC to the HDMI/DVI IN port on the TV. Connect the audio cable from the PC to the Audio input on the TV. (Audio cables are not included yy with the TV). If using a sound card, adjust PC sound as required. yy If the graphic card on the PC does not output analogue and digital RGB simultaneously, connect only yy one of either RGB or HDMI/DVI IN to display the PC output on the TV. If the graphic card on the PC does output analogue and digital RGB simultaneously, set the TV to yy either RGB or HDMI. (The other mode is set to Plug and Play automatically by the TV.) DOS mode may not work depending on the video card if you use an HDMI to DVI cable. yy If you use too long an RGB-PC cable that is too long, there may be interference on the screen. We yy recommend using under 5 m of cable. This provides the best picture quality. ANTENNA ISOLATOR INSTALLATION GUIDE Use this to install TV in a place where there is a voltage difference between GND of power and GND of antenna signal. If there is a voltage difference between GND of power and GND of antenna signal, the antenna contact might be heated and excessive heat might cause an accident. You can improve the safety when watching TV by efficiently removing power voltage from TV antenna. Avoid disconnecting the antenna Isolator after installation. Unpacking and Exterior of antenna isolator Plug 1 Plug 2 Plug 1 Isolator (Type A) Plug 2 Isolator (Type B) Connection method ENGLISH 1 Connect Plug 1 with a signal cable. 2 Connect Plug 2 with ANT input end on the back of TV. Image shown may differ from your TV. yy or Cable / Antenna Isolator TV or Cable / Antenna Isolator Set Top Box TV “Equipment connected to the protective earthing of the building installation through the mains connection or through other equipment with a connection to protective earthing - and to a cable distribution system using coaxial cable, may in some circumstances create a fire hazard. Connection to a cable distribution system has therefore to be provided through a device providing electrical isolation below a certain frequency range (galvanic isolator, see EN 60728-11)” When applying the RF Isolator, a slight loss of signal sensitivity can occur.
