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 now speak all
day in their normal voice without having to raise their voice to get their students’ attention.
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
its many features and options.

setup tips
IMPORTANT!
Be sure you place your Radium speaker and transmitter units on their charger overnight –
for a minimum of 12 hours – before turning the power on and/ or using them for the first
time. Failing to do so can reduce battery capacity.
Basic setup tips
First – Identify a front corner of the room – the location from where the teacher
normally teaches.
diagram 1
Second – Take a good look around, paying close
attention to power outlet and other electronic
equipment locations. Ideally, the speaker should
be placed at a 5-foot distance from other elec-
tronic equipment, such as computers or radios.
Third – Determine whether to mount the
speaker on the wall as shown in diagram 1, or
place it on a sturdy surface using the T-bar table

setup tips (cont’d)
diagram 2
mount stand in diagram 2. In either case,
the speaker should be placed at a height of
3 feet/ 1 meter from the floor, or at level
closest to the listener‘s ears.
Fourth – Consider whether other Radium,
EasyListener 2, or other radio-based active
learning systems are in use in the building,
and set transmitter and receiver channels
accordingly. Every transmitter in a building
should be on its own channel. See
diagrams in section 12 for guidance.
If placing the speaker on a table or surface top, consider the following:
• Choose a loca tion tha t provides ea sy a ccess for the tea cher, a nd is out of
the wa y of students a nd ma in tra ffic a rea s. The speaker should be placed at
least 6 feet/ 1.8 meters away from where the teacher stands.

setup tips (cont’d)
• Choose a table or surface top that is sturdy.
Make sure the table or cabinet is structurally solid, sturdy and out of the way of foot traffic.
• Properly mount a nd securely fa sten the T-ba r spea ker sta nd onto the bottom
of the spea ker. Make sure the stand is screwed on tightly, and that the speaker does
not wobble when in an upright position.
If mounting on the wall, consider the following:
• The power supply cord needs to rea ch the wa ll outlet. Make sure the power
supply is within reach of the speaker from its wall-mounted position.
• The teacher should be able to reach the controls located on top of the speaker
once it’s mounted. Once the volume is set at a comfortable level, the speaker power
switch located on the lower right side of the speaker can be easily accessed by the
teacher. Follow the instructions on page 28 for setting the volume at the proper level.
• Never mount the speaker upside down, or horizontally. The speaker unit must be
mounted such that the controls are located at the top of the unit.

daily operating tips
In the morning –
• Turn tra nsmitter power ’on’ a nd put microphone on.
• Turn spea ker column power ’on’. The speaker should remain plugged into a wall
power outlet during the day – with the power in the ‘on’ position. Turn power switch
to the ‘off’ position at night after each use. The internal battery is not being used while
the speaker is plugged into a wall outlet.
• To opera te using the interna l ba ttery a s a porta ble system, simply unplug the
speaker before use and plug back in after use – making sure you return power switch
to ‘off’ position while plugged-in and charging. The battery takes 6 hours to reach a full
charge; at full charge, the speaker column battery will last up to 8 hours unplugged.
In the evening after each use –
• Turn tra nsmitter power ’off’, and place it back onto the charging stand; confirm
that the ‘charge’ indicator light illuminates. Transmitters not in use should always be
placed on the charging stand – this is their home base station.
• Turn spea ker column power ’off’. Leave speaker plugged into wall power outlet,
but confirm that the power has been turned ‘off.’

Battery care and maintenance tips –
• The speaker battery will last approximately 2 years depending on usage.
• When not in use, leave speaker plugged into wall outlet with power switch in
‘off’ position.
• Keep speaker away from heating units – use/ store in a cool dry place.
• When using speaker battery power (unplugged from wall), always remember to return
power switch to ‘off’ position after use.
• Never mount/ use speaker horizontally or upside down. Controls should be accessible
from top of unit.
• Plan on buying new NiMH batteries for your transmitter every 12 months. Alkaline
batteries can also be used as back-ups, however, the 923C charger will not recharge
alkaline batteries. Never attempt to recharge alkaline batteries – this will cause damage
to the unit and void the product warranty.
• Remember to charge all batteries overnight before initial use.

Do not coil the microphone – since it also acts as your antenna, coiling or wrapping 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.

Follow steps

1
volume setting to proper level. Two people are
needed to set the volume level. It is difficult to
hear your own voice and make adjustments to it.
NOTE: The average volume setting is in the
11:00 position (see photo), but may change
depending on room acoustics and noise level.
With a sound level meter - Take a level reading in the “A” setting in the center of the
room during normal classroom activity, and another reading of the teacher's amplified voice
(without the class activity). The level of the teacher's voice should be set between 10-15
decibels above room noise level.
1
2
Without a sound level meter - First, ask someone other than yourself (if you are the
teacher) to listen to the amplified voice and make volume adjustments. An ideal volume level
is achieved when the listener can hear the amplified voice at a comfortable level and the vol-
ume level from the speaker and teacher’s mouth is comparable. If you can hear yourself
through the loudspeakers, the volume setting may be too high and should be decreased. 28

This transmitter may only be used to provide: audi-
tory assistance to persons with disabilities, persons
who require language translation, or persons in edu-
cational settings; health care services to the ill; law

regulatory approvals and clearances (cont’d)
FCC notes
Part 95
The Radium sound field system is approved by
the FCC (Federal Communications Commission).
The use of the system may be governed by specific
FCC rules and FCC licensing or notifications may
be required. Consult your local FCC office for
detailed information.
This transmitter is authorized by rule under the
Low Power Radio Service (47 CFR Part 95) and
must not cause harmful interference to TV recep-
tion or United States Navy SPASUR installa-
tions. You do not need an FCC license to oper-
ate this transmitter. This transmitter may only be

control communications. Two-way voice commu-
nications and all other types of uses not men-
tioned above are expressly prohibited.

when required, are approved by the Federal
Communications Commission (FCC) in the U.S.
and Industry Canada. Other government
approvals are available upon request. (Other inter-

regulatory approvals and clearances (cont’d)
This device may not cause interference and must
accept any interference received, including inter-
ference that may cause undesired operation.
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.
These devices may not interfere with TV recep-
tion or Federal Government radar.
