Pillow Speaker Setup

Set up pillow speaker after Commercial Mode Setup and Cloning procedures are complete.

Connect a Pillow Speaker to the LCD TV/Monitor

1.Connect the Pillow Speaker to the output jack on the back of the TV.

2.Either:

•Slide the control switch to PILLOW SPEAKER on the rear panel of the TV to control TV and hear audio on pillow speaker.

•For TV speakers sound with pillow speaker control, set the control switch to NORMAL SPEAKER.

Use a pillow speaker that is a UL recognized pendant control bearing the warning: “Risk of fire if used in oxygen enriched atmosphere. Keep pendant 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 an LG patented technology and is being implemented by certain brands of “smart” pillow speakers.

Controlling the TV with Mechanical Switches

Pin 4 (common) is momentarily connected to pin 1, 3, or 6 via push-action switches to control Power 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 8 mA when a switch is closed. (This operation is identical to previous models using the 5-wire interface, except that only +7 volts DC was supplied and current draw was only 2.5 mA.)
