Pillow Speaker Setup - LG 22LG3DDH Setup Manual

Set up pillow speaker after Express Script/Custom Master TV Setup and cloning procedures are complete.
Connect a Pillow Speaker to the LCD TV
1. Connect the Pillow Speaker to the PILLOW SPEAKER
output jack on the rear jack panel of the TV.
2. Either:
• Slide the SPEAKER SWITCH on the rear jack panel
to PILLOW SPEAKER to control the TV and hear
audio on the pillow speaker.
• Slide the SPEAKER SWITCH on the rear jack panel
to NORMAL SPEAKER to hear audio from the TV
speakers with pillow speaker control of the TV.
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.
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. (Optoisolators
isolate the control lines, and a transformer isolates the
audio.) Earth ground is provided on pin 4 (Common) in
the default configuration (e.g., for Zenith/Phillips pillow
speakers). For negative voltage configuration (e.g., for RCA
pillow speakers), +5 volts is provided on pin 4 (Common),
with pin 3 (Channel Up/Data In) referenced to ground.
Pin No. Description
1 External TV ON/OFF switch.

3 External Channel Up switch or Data In.
4 Common connection for control, data, and audio
output.
5 Isolated Audio Output. Nominal 14 ohm source
impedance with short circuit protection. Intended for

volume control.

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.)
