illiams Sound has

been manufac-

turing top quality

hearing assistance equip-

ment since our founding in

1976.

To demonstrate our con-

tinuing quality achieve-

ments, we offer a 5

year warranty on all FM

transmitters and

receivers.

That’s simply the best

warranty in the business.

5 years is a long time to

guarantee anything, much

less electronic equipment.

However, we’re so sure of

the quality built into

Williams Sound products

that we guarantee our

equipment against latent

defects in workmanship

and materials.

This warranty is effective

from the date of retail

sale and applies to

products returned to

Williams Sound for ser-

vice.

As always, accessory

items (earphones, head-

phones, microphones,

etc.) are warranted for 90

days.

RF, Infrared,

Wide–band, or

Narrow–band...

With all the different types

of hearing assistance prod-

ucts available, it’s easy to

get confused about which

type is right for you. It all

depends on your environ-

ment and application.

RF vs. Infrared

For applications where one

signal is needed over a

wide area, RF is often most

appropriate. It provides

consistent coverage with a

single transmitter and sig-

nals pass through walls

and other opaque objects.

It’s often a great choice

for churches, auditoriums,

stadiums, and classrooms.

With infrared systems,

transmission is confined

within opaque walls,

making it a good choice

for movie theaters, board-

rooms, courtrooms, and

anywhere privacy is

valued. Infrared systems

are also immune to radio

interference. Receiver

management is easy with

IR systems because there is

no reason to sort for fre-

quency.

However, IR is not appropri-

ate for outdoor use or

where there is a lot of

direct sunlight. Sunlight

generates infrared interfer-

ence.

Wide–band RF vs.

Narrow–band RF

Wide–band FM systems are

the correct choice when

you need the lowest cost,

a limited number of simul-

taneous channels, good

rejection of radio interfer-

ence, and the highest

fidelity for voice applica-

tions.

Narrow–band FM systems

are the correct choice

when you need the high-

est immunity to outside

radio interference, more

simultaneous channels,

and good fidelity for voice

applications.

FCC Rules

Usage

PPA Transmitters and

Receivers operate under

FCC Rules Part 15 on the

72-76 MHz auditory assis-

tance frequencies.

These systems may only be

used for hearing assistance

for the handicapped and

do not require a license.

The Hearing Helper Tour

Guide System is approved

for general use and may

be used in any facility.

Antennas

FCC rules now require the

use of a “unique” antenna

connector on Part 15 hear-

ing assistance transmitters.

This is to prevent the use of

illegal gain antennas,

which could result in a

higher transmitted field

strength than that permit-

ted by FCC Rules under

Part 15.

Williams Sound standard

Part 15 transmitters have

whip or rubber duckie-type

antennas and remote

antenna connectors which

have been disabled.

If your installation will

require a remote antenna

(rack or cabinet mount,

large listening area, etc.)

you will need an ANT 005

remote coaxial antenna.

If you have any questions

about using a remote

antenna, please call our

Customer Service at

1-800-843-3544.

For rubber duckie or whip

antenna:

Order Standard System or

Transmitter Part Number.

Remote Antenna Needed:

Call Williams Sound for

more information.

Williams Sound FM

hearing assistance sys-

tems operating in the

72–76 MHz band are

approved for use in the

U.S. only. For applica-

tions in other countries,

consult Williams Sound.
