IMPORTANT SAFETY INSTRUCTIONS
(Continued from previous page)
14. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the
product, be sure the antenna or cable system is grounded so
as to provide some protection against voltage surges and
built-up static charges. Article 810 of the National Electrical
Code (U.S.A.), ANSI/ NFPA 70 provides information with
regard to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of
antenna-discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
15. Lightning
For added protection for this product (receiver) during a
lightning storm, or when it is left unattended and unused
for long periods of time, unplug it from the wall outlet and
disconnect the antenna or cable system. This will prevent
damage to the product due to lightning and power-line
surges.
16. Power Lines
An outside antenna system should not be located in the
vicinity of overhead power lines or other electric light or
power circuits, or where it can fall into such power lines or
circuits. When installing an outside antenna system,
extreme care should be taken to keep from touching such
power lines or circuits as contact with them might be fatal.
17. Overloading
Do not overload wall outlets and extension cords as this can
result in a risk of fire or electric shock.
18. Object and Liquid Entry
Never push objects of any kind into this product through
openings as they may touch dangerous voltage points or
short-out parts that could result in a fire or electric shock.
Never spill liquid of any kind on the product.
19. Servicing
Do not attempt to service this product yourself as opening
or removing covers may expose you to dangerous voltage or
other hazards. Refer all servicing to qualified service personnel.
20. Damage Requiring Service
Unplug this product from the wall outlet and refer servicing
to qualified service personnel under the following conditions:
a. If the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the
product.
c. If the product has been exposed to rain or water.
d. If the product does not operate normally by following
the operating instructions. Adjust only those controls that
are covered by the operating instructions as an improper
adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to
restore the product to its normal operation.
e. If the product has been dropped or the cabinet has been
damaged.
f. If the product exhibits a distinct change in performance.
21. Replacement Parts
When replacement parts are required, be sure the service
technician has used replacement parts specified by the manufacturer or have the same characteristics as the original
part. Unauthorized substitutions may result in fire, electric
shock, or other hazards.
22. Safety Check
Upon completion of any service or repairs to this product,
ask the service technician to perform safety checks to determine that the product is in proper operating condition.
23. Wall or Ceiling Mounting

Purchase the Optional Installer’s Remote and Clone Programmer
To preform the installation setup, you need an installer’s remote like the HP602, and the LT1500 Clone Programmer—
both are shown and described in later sections. The installer remote allows access to the Installer menus, User menus,
and Source/Channel Bank keys. The installer remote has Menu, Select, and Adjust Keys (Up/Down/Left/Right arrows) and
Source/Channel Bank Keys. The LT1500 Clone Programmer is used to duplicate a TV’s setup and install it on another TV.
See your Zenith Dealer.
Design and specifications subject to change without prior notice.
Installer/Hospital Note:
Pages 37, 38, 39, and 40 contain information and menus which the patient can use to operate the
TV. It is recommended that these four pages be copied and included with the literature packet that
the hotel provides to the patient.

75 OHM RF CABLE The wire that comes from an off-air antenna or cable service provider. Each end looks like a hex shaped nut with a wire
sticking through the middle, and it screws onto the threaded jack on the back of the TV.
A small device that connects a two-wire 300 ohm antenna to a 75 ohm RF jack. They are usually about an inch long with two screws
on one end and a round opening with a wire sticking out on the other end.

Controlling the TV with serial data
Multiple control functions are handled with a single
wire at pin 3, where digitally encoded serial data is
entered. (Pin 4 is common for all functions.) Pin 3
sources up to 2mA during logic “0” for powering the
encoder in the pillow speaker. The encoder must sink
5 mA minimum from pin 4 (common) during the logic
“1” interval. Pillow speaker A-16455-02 by Curbell
meets this specification
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 +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.)
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. (Opto-isolators isolate
the control lines, and a transformer isolates the
audio. There are no relays or inductive components in
the control lines.)
Pin no. Purpose
1 External TV On/Off switch
2 (not used)
3 External Channel Up switch or Data in
4 Common connection for control, data, and audio output.
Impedance to earth ground is a 10-meg resistor in parallel
with a 1100 pf capacitor.
5 Isolated audio output. Nominal 14-ohm source impedance
with short circuit protection. Intended for a pillow speaker
with a low-impedance pad-type volume control.
6 External Channel Down switch

HealthView TV.
