Lucid HEARING Enlite Hearing Amplifier

INTRODUCTION

The hearing ampliﬁer is a personal sound ampliﬁer that automatically enhances soft sounds. Loud sounds pass through as though nothing is in the ears.
The hearing ampliﬁer provides the highest ﬁdelity sound ampliﬁcation available at any cost. The sound quality of hearing ampliﬁer devices is superior to that of all known custom-ﬁtted devices, and is available without medical referral or prescription.
The circuitry in hearing ampliﬁer devices incorporates a patented new ultra- low-distortion output ampliﬁer, along with all of the important features and beneﬁts of the original K-AMP® circuit ﬁrst described over 30 years ago by Mead Killion, Ph.D., Sc.D.(hon), a well known engineer and professor of audiology. No circuitry,including
digital technology, has proven superior to the sound quality of K-AMP circuitry – the engine of hearing ampliﬁer devices.
INTENDED USE
Etymotic’s hearing ampliﬁer devices have high-frequency emphasis for soft sounds, so the faint sounds of speech can be heard more easily – especially if the speaker is farther away than desirable or speaks very softly. The most common example is someone asking a question from another room. Soft speech can also be heard in a house of worship, classroom, courtroom, lecture hall, theatre, or TV dialog. For many users, hearing ampliﬁer devices are like reading glasses: they are used only part of the time.
Adjusting to hearing ampliﬁer devices

Most hearing ampliﬁer users ﬁnd the eartips comfortable to wear for many hours right away. Others do not.
Take your time.
You may want to wear hearing ampliﬁer devices for short periods until you can wear them for as long as you wish.
If the eartips that come on hearing ampliﬁer devices are not comfortable or do not seal well in the ear, try other eartip styles supplied to determine which size is right for you.

IDENTIFICATION

Lucid HEARING Enlite Hearing Amplifier - fig BATTERY INSERTION
The battery must be inserted correctly or the hearing ampliﬁer will not work.

The battery compartment is located on the underside of the hearing ampliﬁer.
Open the battery door.
Remove the yellow tab from the battery.
Insert the battery with the the ﬂat side facing up.
Do not force the battery into the door.

Note: The door will not close if the battery is not inserted correctly.
BATTERIES (CONTINUED)
Zinc-Air Batteries
Hearing ampliﬁers use commonly-available #10 zinc-air hearing aid batteries. They are easy to ﬁnd in pharmacies, online and other retail locations, including Radio Shack.

Zinc-air batteries have a long shelf life, but once the tab is removed, battery life is about 9 days for continuous operation.
Battery life is about 2 weeks if the devices are turned off after each use.
Once the tab is removed, zinc-air batteries may self-discharge in about 4 weeks whether used or not.
The discharge rate varies with temperature and humidity.
It is sometimes possible to prolong the life of a battery by replacing the tab over the air holes, but results vary.

LOW BATTERY WARNING
Low-Battery Warning
A feature called LOBAT™ alerts you when the battery is at the end of its life.

A slow, quiet ticking sound gradually becomes faster and louder, like the sound of a motorboat.
After the warning sound ﬁrst becomes audible, it may be a few hours before the battery goes dead.
Hearing ampliﬁer performance will not change while LOBAT is sounding.

Estimated Battery Life:
9 days continuous operation
2 weeks (approx) if turned off when not in use

Each Hearing Ampliﬁer uses one #10 zinc-air battery.
Zinc-air batteries do not have to be recycled.
Zinc-air batteries can be disposed in the trash.
Zinc-air batteries are not rechargeable.

SELECTING AN EARTIP
Eartips Lucid HEARING Enlite Hearing Amplifier - fig
1 Selecting an eartip:
No two ears are exactly alike. The eartip that is most comfortable is the best choice, but it must seal well to prevent feedback (whistling).
When changing the eartips, make sure the eartip ﬁts securely on the stem of the device.

INSERTION
Insertion

Make sure the eartip is clean.
Pull the ear up and out while inserting.
Twist and push gently until the eartip seals in the ear canal.
When using 3-ﬂange eartips, moistening may ease insertion.
When using foam eartips, roll down or compress the foam eartip before inserting. Hold the eartip in place for about 5 seconds while foam expands to create a tight seal in the ear canal.
When using glider eartips no compression is needed; simply push into your ear.

REMOVAL
Removal

Remove hearing ampliﬁers with a slow twisting motion.
After removal, place your device(s) in a protective case.

IMPORTANCE OF A DEEP SEAL

Note: Hearing ampliﬁer devices come with a large selection of eartips, including two sizes of 3-ﬂange eartips with long stems. Depending on your ear geometry, the longer stems may allow the deepest seal.
A deep eartip seal ensures the best performance and prevents the “hollow voice” sound, called the occlusion effect.

The occlusion effect is caused by sound transmission into the ear from vibration of the ear canal wall when the ear is occluded by an eartip.
The vibration comes from sound pressure developed in the back of the mouth.
The occlusion effect is most commonly caused by vibration from a person’s own voice, especially from speaking the sounds “ee” and “uu,” or from playing a brass or woodwind musical instrument.
The occlusion effect is worse when there is a shallow insertion of the eartip.
Deeply-sealed eartips reduce the occlusion effect.

OPERATION

ON/OFF
The hearing ampliﬁer turns on and off by opening and closing the battery door.
Note: It is not necessary to remove the battery as long as the door is open wide enough to disable the circuit. LOUDNESS ADJUSTMENT
There are two loudness settings,
Normal (N) and High (H).
N: (switch toward the body of the device)

15-dB mild ampliﬁcation and treble boost for soft sounds.
No ampliﬁcation for loud sounds. H: (switch away from the body of the device)
8-dB more ampliﬁcation than the N position, and treble boost for soft sounds.
Mild ampliﬁcation for loud sounds.

Using the Telephone
It is not necessary to remove the hearing ampliﬁer when using the telephone. If you are comfortable holding the phone on or near the ear and a whistling sound does not occur, the hearing ampliﬁer can remain in the ear during a call.
GENERAL PRODUCT CARE
Simple cleaning with the tool provided will keep the eartip clean and the hearing ampliﬁer working properly.

Use the cleaning tool to pick out or brush off debris.
3-ﬂange eartips can be removed and cleaned in mild detergent. Dry eartips thoroughly before reattaching.
All eartips need to be replaced regularly. With regular use of hearing ampliﬁer devices, 3-ﬂange eartips should be replaced every 60-90 days.
Foam and glider eartips should be discarded and replaced as needed.
Do not use alcohol to clean hearing ampliﬁer devices.
Remove hearing ampliﬁers before using hair products.
Do not expose hearing ampliﬁer devices to extreme heat or moisture.
Avoid dropping or hitting hearing ampliﬁer devices on a hard surface.

CHANGING FILTERS
Each hearing ampliﬁer has a special ﬁlter that enhances sound quality and prevents earwax from entering the device. A ﬁlter should be changed if the volume decreases or sound quality declines.
Filter Removal
Note: Use the tool to remove the ﬁlter.

1. Remove eartip.| 2. Insert tool into the ﬁlter.| 3. Remove ﬁlter.

Filter Replacement
Note: Do not use the tool to replace the ﬁlter.

Insert a new ﬁlter.
Press gently against a hard surface to secure it in place.
Re-attach eartip.

TROUBLESHOOTING

Problem: No sound.
What to do:

Check to see if hearing ampliﬁer is turned on (battery door closed).
Clean the eartip and the end of the hearing ampliﬁer.
Try a fresh battery.
Replace the ﬁlter.

Problem: Sound is not loud enough.
What to do:

Try the H (high) setting for more ampliﬁcation.
Clean the eartip and the end of the hearing ampliﬁer.
Replace the ﬁlter.

Problem: “My voice sounds hollow” or “There is an echo in my voice”.
What to do:
You may be experiencing the occlusion effect. See p.9.
Make sure the eartip seals deeply in the ear. You may need to try an eartip with a long stem.
CAUTION
Consult an audiologist or physician if you have excessive ear wax, difﬁculty inserting the eartips, or discomfort after prolonged use.
In rare instances an eartip may come off in the ear canal when removing a hearing ampliﬁer. If this should occur and the eartip cannot be easily removed, it is recommended that you promptly contact an audiologist or other medical professional. A professional can use blunt tweezers to remove the eartip.
Hearing ampliﬁer devices are made from materials and components that are standard in consumer audio products and hearing
protection devices.
Allergic reactions are uncommon. If redness, soreness or other adverse reactions occur, discontinue use and contact a medical practitioner.
CAUTION (CONTINUED)
Do not shower or swim while wearing the hearing ampliﬁer.
The hearing ampliﬁer allows up to 115 dB SPL -weighted to pass through. Do not use the hearing ampliﬁer in loud environments. Avoid use when exposed to prolonged loud sound.
** Keep hearing aids out of the reach of children or anyone who may accidentally swallow them. Never put hearing ampliﬁers in your mouth for any reason. Do not store in pill containers where they may be mistaken for medication and swallowed.
BATTERY WARNING**

Batteries (in the battery pack or installed in the device) should not be exposed to excessive heat such as ﬁre, sunshine or similar adverse environment.

BATTERY WARNING (CONTINUED)

Batteries of low quality may leak and cause bodily harm. Batteries with incorrect voltage may cause damage to your device. They may explode and cause serious injury. Do not expose your hearing aid to heat, such as an open ﬂame, microwave, or oven. There is a risk that they will explode and cause serious injury.
