Connect a piLLow speaker to the LED W/Monitor.
Locate the PiLLowSpeaker output jack on the back of
the LCD W/Monitor.
Connect an accessory piLLow speaker or wired remote
control unit to this 6-pin jack.
SeLect PILLOW SPEAKER on the rear panel of the
LCD W/Monitor.
*Notes:
If the pillow
Speaker switch
is set to Pillow Speaker,
no
sound will be heard [rom the TV speakers.I[ 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 Curbett, Model A-16455-02
or
other UL recognized pendant control bearing the warning:
"Risk
of fire if used in oxygen enriched
atmosphere.
Keep pendant contro[ away from oxygen equipment."
Controlling
the TV with Serial Data
The TV is capable
of being controLLed by a sing[e-wire,
serial data signaL. This is a Zenith
patented
technology
and is being implemented
by certain
brands of "smart"
piLLow speakers,
such as CurbeU'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 cat[ system
may be
connected
here. At[ Lines are isolated
from the AC
power Line and earth ground.
(Opto-isotators
isolate
the control
Lines, and a transformer
isolates
the audio.
There are no relays or inductive
components
in the
control
Lines.)

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 8 mA
when a switch is closed.
(This operation
is identical
to
previous
Zenith models
using the 5-Wire Interface
except
that
only +7 volts
DC was supplied
and current draw was
only 2.5 mA.)
