introduction
Congratulations on the purchase of your new Radium sound field system! With proper care
and use it will become one of your most valuable classroom educational tools. Students will
be able to consistently and easily understand the teacher, regardless of their location in the
classroom, or competing internal or external background noise. Teachers can speak all day
in their normal voice, and will suffer far fewer vocal problems and absenteeism.
Numerous studies show that classrooms using sound field enjoy better student comprehen-
sion, increased student participation, better grades and fewer behavioral referrals.
Read this manual carefully to become familiar with your system and to get the most out of
it’s many features and options.

Before you set your system up, take a good look around your room. Where are the outlets
located? Where are the computers and other electronic equipment? Where can you put your
speaker so it's easy for you to reach, but out of the way of students and main traffic areas?
Though each classroom is different, there are some general
guidelines for speaker placement:
The speaker should be at the front of the
classroom at least 6 feet/1.8 meters away
from where the teacher stands. Try to
keep it at least six feet away from
computers or other electronic equipment,
since there may be interference if placed
too closely together.

basic system guidelines
To help ensure that you get the most from this system, we have put together a list of sug-
gested guidelines.
Charge transmitter batteries every night. Our rechargeable Nickel Metal Hydride
batteries last approximately 12 hours between charges, but should be recharged every
night so they are ready to go in the morning. Plan on buying new NiMH batteries after
12 months of use. Alkaline batteries can also be used, and they will last approximately
15 hours. NEVER attempt to recharge alkaline batteries! This will cause damage to the
transmitter units and may invalidate product warranty.
Charge the 920SR receiver batteries every night. The column speaker rechargeable
battery lasts approximately 5- 8 hours between charges, but should be recharged every
night so it’s ready to go in the morning. For daily use, we recommend unplugging the
power supply cord, allowing the battery to power the unit. Continuous, daily operation with
the power supply cord plugged in will reduce the life of the battery significantly.
Do not coil the microphone cord. Since it also acts as your antenna, coiling or wrap-
ping the cord will affect its range and may also reduce its life.
Speak at a normal level — the system is projecting your voice for you. 4

code of federal regulations (United States only)
21 C.F.R., part 801.420 - important notice
for prospective hearing instrument users
Good health practice requires that a person with a
hearing loss have a medical evaluation by a licensed
physician (preferably a physician who specializes in
diseases of the ear) before purchasing a hearing
instrument. Licensed physicians who specialize in dis-
eases of the ear are often referred to as otolaryngolo-
gists, otologists, or otorhinolaryngologists. The pur-
pose of a medical evaluation is to assure that all med-
ically treated conditions that may affect hearing are
identified and treated before a unit is purchased.
Following the medical evaluation, the physician
should give you a written statement which states your
hearing loss has been medically evaluated, and that
you may be considered a candidate for a hearing
instrument. The physician should refer you to an
audiologist or hearing aid dispenser, as appropriate,
for a hearing instrument evaluation.
The audiologist or hearing aid dispenser will conduct a
hearing instrument evaluation to assess your ability to
hear with and without a hearing instrument. The eval-
uation will enable the audiologist or dispenser to select
and fit a unit best suited to your individual needs.
If you should have reservations about your ability to
adapt to amplification, you should inquire about the
availability of a trial rental or purchase-option program.
Many dispensers now offer programs that permit you
to wear the hearing instrument for a period of time
for a nominal fee after which you may decide if you
want to purchase that unit.
Federal law restricts the sale of hearing instruments to
those individuals who have not obtained a medical
evaluation from a licensed physician. Federal law per-
mits a fully informed adult to sign a waiver statement
declining the medical evaluation for religious or per-
sonal beliefs that preclude consultation with a physi-
cian. The exercise of such a waiver is not in your best
interest and its use is strongly discouraged.

code of federal regulations (cont’d)
children with hearing loss
In addition to seeing a physician for a medical evalua-
tion, a child with a hearing loss should be directed to
an audiologist for evaluation and rehabilitation since
hearing loss may cause problems in language develop-
ment and the educational and social growth of a child.
An audiologist is qualified by training and experience
to assist in the evaluation and rehabilitation of a child
with a hearing loss.

IC notes
This Class B digital apparatus complies with
Canadian ICES-003.
Cet appareil numérique de la classe B est
conforme à la norme NMB-003 du Canada.
The term "IC:" before the radio certification
number only signifies that Industry of Canada
technical specifications were met.
This device may not cause interference and must
accept any interference received, including inter-
ference that may cause undesired operation.
These devices may not interfere with TV recep-
tion or Federal Government radar.
If TV channel 13 is used in the area, the installer
shall reduce or adjust the RF radiated power so
that near-by TV channel 13 receivers do not
receive radio interference from the system
installed. Suggestions: A test with a TV receiver
equipped with "rabbit-ear antenna" and tuned to
channel 13 should be conducted, at the perimeter
of the users' intended coverage area and not
over-lapping other user's areas without the latter's
consent. If this does not solve the problem, a
channel near the 217 MHz edge and not near
216 MHz should be tried.
