introduction
Congratulations on the purchase of your new EasyListener 2 sound field system! With proper
care and use it will become one of your most valuable classroom tools for many years.
Students will be able to consistently and easily understand what the teacher is saying,
regardless of his/her location in the classroom. Teachers can now speak all day in their
normal voice and will suffer far fewer vocal problems as a result.
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.

Before you set up your system, 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
receiver 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 both receiver and
speaker placement:
The receiver — should be in the front of the classroom at teacher's eye level when standing,
close to a wall outlet. Try to keep it at least six feet (19.5 meters) away from computers or other
electronic equipment, since there may be interference if it is placed too close to these devices.
Compact wall speakers — should be mounted as high as possible and angled down
toward the listeners' ears. Place them around the room so there is even coverage in the listening
area (where the students are seated). Use as many as needed — four is recommended.*
Distributed ceiling speakers — space them evenly above the students’ seating area.
A minimum ceiling height of 10 feet is necessary, and 12 feet is even better. Use as many
as needed — a minimum of four is recommended.*
Cluster ceiling speaker — should be centered directly over the students’ seating area.
A minimum ceiling height of 12 feet is recommended, and 14 feet is even better.
* For optimal speaker placement, download Sound field Wizard software from our website at www.phonicear.com.

basic system guidelines
To help ensure that you get the most out of your new sound field system, we have put
together the following list of suggested guidelines:
Charge the batteries every night. Rechargeable Nickel Metal Hydride batteries (included
with system) 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 (only
Phonic Ear brand can be used) after 12 months of use. Alkaline batteries can also be used
as backups, and will last approximately 15 hours. Alkaline batteries cannot be recharged
by the system.
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.
Periodically check the volume and OptiVoice settings. These are often set and
then forgotten, but if accidentally changed, will affect how your system sounds.

adjusting OptiVoice™ setting

10
low: Recommended for use in low-noise situations and for most natural voice quality.
medium: Recommended for everyday use. Best setting for average classrooms where low-
medium noise levels are present.
high: Recommended for use in high noise levels. Helps to ensure top comprehension
during critical tasks such as test-taking or hearing impaired instruction.
NOTE: With each increase in level, there is an increase of approximately 3dB in gain
(volume). This may require you to decrease your volume setting to avoid potential micro-
phone/speaker feedback.
OptiVoice is a 3-position switch that automati-
cally adjusts the sound quality of the primary
speaker’s voice. It allows teachers to shape the
sound of their voice and helps to ensure maxi-
um speech clarity in low, medium and high
noise levels.

Follow steps or below to adjust FM
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.
setting FM volume

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.
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 is too high and should be decreased
NOTE: The average volume setting is
between 4–5, but may change depending
on room acoustics and noise level.

where to mount compact wall speakers
Based on your classroom acoustics and seating
arrangement, speaker placement will vary.
• For an average sized classroom, 4 speakers
are recommended
• Mount on walls, ceiling beams, or other
structure
• Place speakers as high up as possible
• Aim speakers down toward listeners’ faces.
• The farthest listener each speaker can
serve should be less than twice as far
away as the closest listener. (D2<2D1
in diagram)
For optimal speaker placement, download our
sound field wizard software from our web
site at www.phonicear.com.

adjusting 3-band equalizer
(This setting should be adjusted by sound professionals ONLY)
31
Use screwdriver to adjust the low,
mid and high settings. Turn to the
right to add base, mid and high
tones. Turn left to decrease.
A properly adjusted equalizer opti-
mizes the system’s sound quality and
reduces feedback.
Making improper adjustments could
result in a degradation in sound qual-
ity and performance.

ATTENTION: If you are not a sound profes-
sional, we do not recommend that you alter
the 3-band equalizer settings.

adjusting squelch
(This setting should be adjusted by sound professionals ONLY)
32
Using a screwdriver turn the control slightly to
the left (counter clockwise) to increase the sys-
tem's range and to the right (clockwise) to
decrease the system's range.
1
The squelch setting increases or decreases the sys-
tem’s range by disabling the receiver audio when
the transmitter signal is below the threshold point.
It also allows the ability to re-use a channel, pro-
vided that systems coverage area is installed more
than 200ft apart (indoors). For best results, ask someone to help you by wearing the trans-
mitter and walking away from the base station receiver towards the perimeters of the room.
When you begin to hear noisy static, you know you've reached the system's internal range
limits. Increase or decrease the range slightly, and re-test by repeating this step. (In most
cases the system's range will go well beyond the typical classroom.)
If noise or signal interference persists, make sure systems in adjacent classrooms are turned
off. Re-test range and set squelch for the minimum system range to reduce external interfer-
ence. Contact Phonic Ear Service if extra assistance is required.

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.
3745 EL2 System User Guide 2/24/04 4:30 PM Page 72

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.
transmitter
