introductionCongratulations on the purchase of your new EasyListener 2 sound field system! With propercare 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 ofits many features and options.13745 EL2 System User Guide 2/24/04 4:29 PM Page 7

Before you set up your system, take a good look around your room. Where are the outletslocated? Where are the computers and other electronic equipment? Where can you put yourreceiver 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 andspeaker 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 otherelectronic 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 downtoward the listeners' ears. Place them around the room so there is even coverage in the listeningarea (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 manyas 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. installation tips33745 EL2 System User Guide 2/24/04 4:29 PM Page 9
basic system guidelinesTo help ensure that you get the most out of your new sound field system, we have puttogether the following list of suggested guidelines:Charge the batteries every night. Rechargeable Nickel Metal Hydride batteries (includedwith system) last approximately 12 hours between charges, but should be recharged everynight so they are ready to go in the morning. Plan on buying new NiMH batteries (onlyPhonic Ear brand can be used) after 12 months of use. Alkaline batteries can also be usedas backups, and will last approximately 15 hours. Alkaline batteries cannot be rechargedby 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 andthen forgotten, but if accidentally changed, will affect how your system sounds.43745 EL2 System User Guide 2/24/04 4:29 PM Page 10

21adjusting OptiVoice™ setting1Set OptiVoice switch to medium110low: 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 primaryspeaker’s voice. It allows teachers to shape thesound of their voice and helps to ensure maxi-um speech clarity in low, medium and highnoise levels.3745 EL2 System User Guide 2/24/04 4:29 PM Page 27
22Follow steps or below to adjust FMvolume setting to proper level. Two people areneeded to set the volume level. It is difficult tohear your own voice and make adjustments to it.setting FM volume1111With a sound level meter - Take a level reading in the “A” setting in the center of theroom 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 10-15decibels above room noise level.Without a sound level meter - First, ask someone other than yourself (if you are theteacher) to listen to the amplified voice and make volume adjustments. An ideal volume levelis 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 yourselfthrough the loudspeakers, the volume setting is too high and should be decreased NOTE: The average volume setting isbetween 4–5, but may change dependingon room acoustics and noise level.2123745 EL2 System User Guide 2/24/04 4:30 PM Page 28

52adjusting 3-band equalizer (This setting should be adjusted by sound professionals ONLY)31Use screwdriver to adjust the low,mid and high settings. Turn to theright to add base, mid and high tones. Turn left to decrease. A properly adjusted equalizer opti-mizes the system’s sound quality andreduces feedback.Making improper adjustments couldresult in a degradation in sound qual-ity and performance.11ATTENTION: If you are not a sound profes-sional, we do not recommend that you alterthe 3-band equalizer settings.3745 EL2 System User Guide 2/24/04 4:30 PM Page 58
53adjusting squelch(This setting should be adjusted by sound professionals ONLY)32Using a screwdriver turn the control slightly tothe left (counter clockwise) to increase the sys-tem's range and to the right (clockwise) todecrease the system's range.1The squelch setting increases or decreases the sys-tem’s range by disabling the receiver audio whenthe 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 morethan 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 rangelimits. Increase or decrease the range slightly, and re-test by repeating this step. (In mostcases the system's range will go well beyond the typical classroom.)If noise or signal interference persists, make sure systems in adjacent classrooms are turnedoff. 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.13745 EL2 System User Guide 2/24/04 4:30 PM Page 59

66code of federal regulations (United States only)21 C.F.R., part 801.420 - important noticefor prospective hearing instrument usersGood health practice requires that a person with ahearing loss have a medical evaluation by a licensedphysician (preferably a physician who specializes indiseases of the ear) before purchasing a hearinginstrument. 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 areidentified and treated before a unit is purchased.Following the medical evaluation, the physicianshould give you a written statement which states yourhearing loss has been medically evaluated, and thatyou may be considered a candidate for a hearinginstrument. The physician should refer you to anaudiologist or hearing aid dispenser, as appropriate,for a hearing instrument evaluation.The audiologist or hearing aid dispenser will conduct ahearing instrument evaluation to assess your ability tohear with and without a hearing instrument. The eval-uation will enable the audiologist or dispenser to selectand fit a unit best suited to your individual needs.If you should have reservations about your ability toadapt to amplification, you should inquire about theavailability of a trial rental or purchase-option program.Many dispensers now offer programs that permit youto wear the hearing instrument for a period of timefor a nominal fee after which you may decide if youwant to purchase that unit.Federal law restricts the sale of hearing instruments tothose individuals who have not obtained a medicalevaluation from a licensed physician. Federal law per-mits a fully informed adult to sign a waiver statementdeclining 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 bestinterest and its use is strongly discouraged.3745 EL2 System User Guide 2/24/04 4:30 PM Page 72
67code of federal regulations (cont’d)children with hearing lossIn addition to seeing a physician for a medical evalua-tion, a child with a hearing loss should be directed toan audiologist for evaluation and rehabilitation sincehearing loss may cause problems in language develop-ment and the educational and social growth of a child.An audiologist is qualified by training and experienceto assist in the evaluation and rehabilitation of a childwith a hearing loss.transmitterThis transmitter is authorized by rule under the LowPower Radio Service (47 C.F.R.
