PILLOW SPEAKER SETUP (Except 32LG3DC)

Connect a pillow speaker to the LCD TV/Monitor.

1. How to connect

Connect the PILLOW SPEAKER output jack on the

1back of the TV.

2Connect an acccessory pillow speaker or wired remote control unit to this 6-pin jack.

Select PILLOW SPEAKER on the rear panel of the

3TV.

NOTE: If the pillow speaker switch is set to Pillow Speaker, no sound will be heard from the TV speakers. Also, Auto Volume will be grayed out and not accessible on the Sound menu.

Use a pillow speaker that is a UL recognized pendant control bearing the warning:

“Risk of fire if used in oxygen enriched atmosphere. Keep pen- dant control away from oxygen equipment.”

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.

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. (Optoisolators 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 +13volts DC(when measured from pin4) with the switches open. Current draw is 8 mA 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.)
