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 ﬁ re 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.)

Pin No.
