If this is your first experience in wearing high fidelity devices, it is important 
to know that you should expect to hear improved clarity of sound and ease 
of understanding in every day situations. Do not expect to experience an

Your Simplicity uses a zinc-air #10 battery. 
Do not remove the air activation tab until 
you are ready to install the battery. 
To open the battery door, place your thumb-
nail under the lip of the door and gently lift. 
Note: The battery has two distinct sides. The 
positive side (+) is flat and the negative side 
(-) is rounded. Insert the round side first 
into the battery door. If properly seated, the 
flat side should be flush with the top of the 
battery door. The battery door should easily 
snap shut. Do not use force to close the door, 
damage to the device may result. 

To remove the battery,

 open the door and 

push the battery up and away from the lipped side of the door or use the 
magnetic end of the utility brush to easily lift out the battery.


Try to wear your hearing aid daily. Occasional use will not allow you to at-
tain full benefit from your hearing aid. Allow for a period of adjustment in 
your routine listening environment. It will take a period of time to become 
fully adjusted to hearing certain sounds again. 
If you have purchased a single aid, we suggest that you consider purchas-
ing a device for your other ear. Amplification for both ears provides a sense 
of hearing balance and allows you to reduce the amount of volume needed by 
a single aid.
Hearing aids will not restore normal hearing and will not prevent or improve 
a hearing impairment. 
Discontinue use of your aids(s) and consult with your physician if you 
notice any of the following symptoms:

 skin irritation

 increased production of earwax

 any pain associated with the ear

Look at the base of the Dome Flex Tip for a blue or red marking. Blue 
indicates the left ear and red for the right (see page. 1).

 Place the Sim-

plicity device on top of the ear with the ear hook hanging over the front of 
the ear (Fig. 1). The earmold should be oriented so that the tubing is facing 
toward the opening of the ear canal. Gently push in the tip (red or blue) of 
the tubing into your ear canal (Fig. 2).
After inserting the tip of the Dome Flex-tip into the ear canal, seat the 
retention cord into the bottom bowl of ear (Fig. 3).

   Fig. 1                                            Fig. 2                                             Fig. 3


A hearing aid dispenser should advise a prospective hearing aid user to 
consult promptly with a licensed (preferably an ear specialist) before 
dispensing a hearing aid if the hearing aid dispenser determines through 
inquiry, actual observation, or review of any other available information 
concerning the prospective user, that the prospective user has any of the 
following conditions:

• Visible congenital or traumatic deformity of the ear.
• History of active drainage from the ear within the previous 90 days.
•  History of sudden or rapidly progressive hearing loss within the previous 90 days.
• Acute or chronic dizziness.
•  Unilateral hearing loss of sudden or recent onset within the previous 90 days.
•  Audio metric air-bone gap equal to or greater than 15 decibels at 500 hertz (Hz), 

1,000 Hz, and 2,000 Hz.

•  Visible evidence of significant cerumen accumulation or a foreign body in the ear 


• Pain or discomfort in the ear.

To turn your device on:


Insert battery into battery door and close the door. Insert into 
your ear, then rotate the volume control slowly to the right.

To turn your device off: 

Rotate volume control to the left. You should feel a slight  
click when full “off” position is achieved. Do not force the  
volume control, damage may occur. Or, open battery door  
fully so that the battery is no longer making contact with  
the device. This will allow you to leave the volume control  
at your favorite listening level without  
any readjustment. 


 If you detect a high pitched 

whistling sound coming from the device, 
turn down the volume slightly, check the  
positioning of the sound tube in your ear,  
then slowly increase the volume to a desired level.



If you have reservations about your ability to adapt to amplification, you 
should inquire about the availability of a trial-rental or purchase option 
program. Many hearing aid dispensers now offer programs that permit 
you to wear a hearing aid for a period of time for a nominal fee after 
which you may decide if you want to purchase the hearing aid.
Federal law restricts the sale of hearing aids to those individuals who have 
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 personal beliefs that preclude consultation with a 
physician. The exercise of such a waiver is not in your best health interest 
and its use is strongly discouraged.

Children with a hearing loss.

 In addition to seeing a physician for a 

medical evaluation, a child with a hearing loss should be directed to an 
audiologist for evaluation and rehabilitation since hearing loss may cause 
problems in language development 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.

Low Battery Warning 

The Simplicity features a low battery warning 
alert. When the battery is in need of changing, 
you will hear a low, “motorboating” sound which 
becomes louder and faster as the battery power 
becomes weaker.

Zinc-Air Battery Information 

Your Simplicity uses a zinc-air #10 battery (yellow 
tab). Peel off the paper activation tab prior to use. 
To keep your device performing at peak efficiency,  
use only premium zinc-air batteries.

Helpful hint #1. 

Be sure NOT to remove the pull-tab off the back of the 

battery until you are ready to install it in the device. This will provide the 
longest possible operating life. 

Helpful hint #2.

 Open the battery door to your device when not in use to 

rest the battery and to allow any moisture build-up to escape.

Remove activation tab



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 aid.  
Licensed physicians who specialize in diseases of the ear are often referred 
to as Otolaryngologists, Otologists, or Otorhinolaryngologists. The purpose 
of a medical evaluation is to assure that all medically treatable conditions 
that may affect hearing are identified and treated before the hearing aid is 
Following the medical evaluation, the physician will give you a written 
statement that states that your hearing loss has been evaluated medically 
and that you may be considered a candidate for a hearing aid. The physician 
may refer you to an audiologist or a hearing aid dispenser, as appropriate, for 
a hearing aid evaluation.
The audiologist or hearing aid dispenser will conduct a hearing aid evalu-
ation to assess your ability to hear with and without a hearing aid. The 
hearing aid evaluation will enable the audiologist or dispenser to select and 
fit a hearing aid to your individual needs.

1.  At the end of each day, remove your Simplicity, clean the exterior with 

a tissue and inspect the opening of the earmold tubing for any blockage, 
moisture, or wax buildup. 

2.  Brush the sound port on a daily basis. Make sure the end of the tube is 

pointed downward so that loose debris will not be pushed further into 
the tubing. 

3.  Open battery door when device is not in use.
4. Do not expose your device to direct or excessive heat. 

When storing your Simplicity for an extended period of time: 

1. Remove the battery.  
2. Place device in the presentation case or travel pouch.  
3. Store the device in a cool, dry place, (not refrigerator.) 


1. Do not drop or throw your device. Internal damage may result. 
2.  Keep your device away from excessive heat (stove tops, hair dryers,  

microwave ovens, heat lamps) or in the glove compartment of your car. 

3. Do not get your device wet while bathing, showering or swimming. 
4.  Do not pry open the case of your device or attempt to repair it. This will void your 

warranty and possibly cause further damage to the device. 

5.  Keep your Simplicity and all hearing devices out of reach of children and animals.

Battery Warning: 

Batteries are dangerous if consumed. Keep batteries out 

of reach of children and animals. 

•  Discard batteries properly, never place in fires or near flames. 
•  Never allow children to play with batteries 
•  Never put batteries in your mouth for any reason 
•   Always check medication before swallowing because batteries have been mistaken 

for tablets. 

If a battery has been swallowed: Call the National Button Battery 
Ingestion Hot line: (202) 625-3333 for counseling on treatment

Feedback is the result of amplified sounds reflected back into the micro-
phone. Adjusting the device with your hand close to the device will also 
cause feedback.  This is normal occurrence with amplification devices. 
If your are experiencing any feedback problems, try one or more of the 
following suggestions:
• Check to ensure device is fully seated into your ear canal
• Make sure left device (blue) is in left ear and (red) for the right
• Slightly decrease the volume
• Inspect the sound port for blockage

Using the telephone

Your Simplicity device allows you to use the telephone in a completely 
normal manner. Place the receiver to your ear as usual. If you hear a high-
pitched whistling noise (feedback) tilt the receiver slightly away from your 
ear until the noise stops.

Cleaning the poly-tube

Slowly insert the cleaning filament end of the 
Simplicity multi-tool into the sound port of the 
dome flex-tip. Push the filament through the 
dome completely to ensure all debris has been 
removed. If you are unable to clear the blockage, 
please contact the Readywearexpress customer 
service dept. (page 18).
With the dome removed, insert the filament line 
into the opening of the dome. Push the filament 
through the dome completely to ensure all debris 
has been removed.
Reinsert the flex dome on to the poly-tube, then 
insert tubing connector into opening of the device 
with a slight back and forth twisting motion and 
push into place. Rotate the tube turn it back to its 
original position.


Removing the poly-tube

Turn the tubing (at connector base) left or right 
ninety degrees from its original position.  
Be sure to turn the tubing at the base where the 
tube inserts in to the device, otherwise damage to 
the tubing could occur. 
The tubing position should change from directly 
behind the device to parallel to its side. With a 
slight back and forth twisting motion, pull apart 
the device and poly-tubing.
After the poly-tube has been removed, the  
dome flex tip will need to be separated from the 
tube. Remove the dome flex-tip from the poly-tube 
by gently twisting the poly-tube and pulling the 
dome tip. Do not pull the dome by the outer edge, 
hold the dome at the base where it connects to the
