Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code (U.S.A.), ANSI/NFPA 70 provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.

Be sure the style of stand selected is capable of supporting the weight of the TV.
If the mount will be on a wall, a typical wooden stud behind the wall board would be the preferred choice for a location to attach the wall mount. The wall mount location chosen should be appro-priate for drilling holes and have available the required power source as well as antenna/cable and other equipment leads.
For pedestal-type mounts, a sturdy surface on a desk or other similar flat table-like surface would be the appropriate location for mounting a pedestal-style TV stand. (Some stands are portable and can be moved from one location to another.) Be sure all safety considerations are followed.
Most stands are designed so that the wiring would be threaded through the stand itself or a loop-through style clamp so that the wiring is neatly bunched and not strung in such a way as to create a potential hazard to the user.

G Screw length needed depends on the wall mount used. For further information, refer to the VESA Wall Mounting Instruction Guide.

G To get the the best picture quality, adjust the PC graphics card to 1024x768, 60Hz.
G Depending on the graphics card, DOS mode may not work if a HDMI to DVI Cable is in use.
G Check the image on your TV. There may be noise associated with the resolution, vertical pattern, contrast or brightness in PC mode. If noise is present, change the PC output to another resolution, change the refresh rate to another rate or adjust the brightness and contrast on the
VIDEO 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.
G Avoid keeping a fixed image on the screen for a long period of time. The fixed image may become permanently imprinted on the screen.
G The synchronization input form for Horizontal and Vertical frequencies is separate.

*Note: If the pillow Speaker switch is set to Pillow Speaker, no sound will be heard from the TV speakers. If pillow speaker switch is set to the Pillow Speaker position, Auto Volume will be grayed out and not accessible on the Sound menu.
Use a pillow speaker by Curbell, Model A-16455-02 or other UL recognized pendant control bearing the warning: “Risk of fire if used in oxygen enriched atmosphere.
Keep pendant control away from oxygen equipment.”
Pillow speaker not included with TV.
Controlling the TV with Serial Data
The TV is capable of being controlled by a single-wire,
serial data signal. This is a LG patented technology and is being implemented by certain brands of “smart” pillow speakers, such as Curbell’s “GEN-II” models.
Pillow Speaker Interface
This connector furnishes three control lines and an audio output. A patient-pendant remote control, or entertainment audio and nurse call system may be connected here. All lines are isolated from the AC power line and earth ground. (Opto-isolators isolate the control lines, and a transformer isolates the audio. There are no relays or inductive components in the control lines.)

Controlling the TV with Mechanical Switches
Pin 4 (common) is momentarily connected to pin 1, 3, or 6 via push-action switches to control On/Off and Channel Up/Down. These pins are at +13 volts DC (when measured from pin 4) with the switches open. Current draw is 8mA when a switch is closed. (This operation is identical to previous LG models using the 5-Wire Interface except that only +7 volts DC was supplied and current draw was only 2.5 mA.)
