User Manual

Introduction to this booklet
The User Manual guides you in how to use and maintain your new hearing device. Please read the User Manual
carefully. This will help you achieve the full benefit of your new hearing device.
Your hearing healthcare provider has adjusted your hearing device to meet your specific needs. If you have additional
questions or wish to report an unexpected operation or event, please contact your hearing healthcare provider.
Please Note:
 The use of hearing devices is only part of hearing rehabilitation; auditory training, lip reading
instruction, and learning to interpret gesture cues may be required as well.
 In most cases, infrequent use of hearing devices does not provide full benefit. Once you have become
used to wearing your hearing devices, wear your hearing devices all day every day.
 Your hearing devices use the most modern components to provide the best possible sound quality in
every listening situation. However, communication devices such as digital cell phones can create
interference (a buzzing sound) in hearing devices. If you experience interference from a cell phone
being used close by, you can minimize this interference in a number of ways. Switch your hearing
devices to another program, turn you heard in a different direction or locate the cell phone and move
away from it.

Intended Use
Hearing devices are sound-amplifying devices intended to compensate for impaired hearing. A hearing device will not
restore normal hearing, and will not prevent or improve biologic hearing sensitivity resulting from damage.

Figure shows Step 3 in the directions above.
Battery
The hearing device uses a size 312 battery. The battery life varies, depending on the amount of time the hearing device
is used. Battery life is typically 5-8 days long in hearing device mode.
Inserting/replacing the battery:
1. Gently pull open the battery door with your fingernail. Remove the old battery, if present.
2. Insert the new battery into the battery compartment with the (+) sign on the battery facing the same way as the
(+) sign on the battery door. While holding the battery in place, peel off the tab. (As shown in the figure below.)
To ensure best battery performance, wait 15-30 seconds before closing the battery door after
peeling the plastic tab. If the door does not close easily, check to see if the battery was inserted
properly.
3. Close the battery door.
Tip: To prolong battery life, remember to turn your hearing device off when not in use.
Remove the batteries and keep the battery door open will not only conserve the battery’s
life but also allow internal moisture to evaporate.
Tip: Since the battery sits in the battery door, the door should be opened gently and slowly
so that the battery does not fall out.

Maintaining Your Hearing Device
Ear wax is natural and common. For some users, wearing a hearing device will increase the production of ear wax.
Ensuring that your hearing device is free of wax obstruction is an important part of the cleaning and maintenance of
your hearing device.
Depending on your requirements, your hearing device will have a thin tube and dome tip or a conventional earmold
attached to it. Review the warnings below and follow the instructions on next pages.
CAUTION: Not following the list below may cause damage to your hearing device and accessories
 Do not immerse your hearing device in water or liquid to clean. Instead, use a soft cloth or tissue
to remove moisture or oil residue.
 Do not bend the thin tube and tip back and forth to remove it.
 Do not use cleaning wire while the thin tube is connected to the hearing device.
 Do not use alcohol to clean your earmold or dome tip.
 Do not use sharp tools to dislodge ear wax.
 If your physician prescribes ear drops, clean any moisture that may get into the earmold or tubing.

Using with Telephones and Cellular Phones
Traditional corded phones, cordless phones, and cellular phones.
First, try to use the phone as you normally would hold it. If you cannot hear well, move the handset to find the position
that sounds best to you. Some users find performance can be improved by tilting the handset towards the hearing
device. It may help to turn the volume up on your phone.
Practice using the telephone with someone familiar to you. Try moving the phone around to get the best sound.
Telecoils
Your device contains a telecoil which needs to be activated by your hearing healthcare provider. The telecoil converts
electromagnetic signals directly from the telephone into sound. To use the telecoil, select the appropriate program
setting, using the push button. The telecoil setting may allow you to hear more clearly on the telephone. After finishing
your phone call, change back to your preferred listening program.
If your phone is labeled “Hearing Device Compatible,” it works with a telecoil.
Other uses of a telecoil
Many people use the telecoil with assistive listening devices called induction loops. If you go to a public event, and the
room is “looped,” then you can use your telecoil. Set your hearing device to the telecoil program. Sound is transmitted
to your hearing device, allowing you to hear the speaker more clearly. After the event, change back to your preferred
listening program.
Note: If you are in a location with an induction loop system, you will notice this symbol. This means the
location you are presently in has special accommodations for the hearing impaired.

Airplane Mode
When boarding an airplane or entering an area where radiated radio signals are prohibited, wireless functionality must
be deactivated; airplane mode must be turned on.
The airplane mode is enabled by closing the battery door while pressing the volume button for six seconds.
To disable airplane mode, open and close the battery door.

Labeling
The serial number (S/N) is located on the hearing device as an 8-digit number. The first two digits of the S/N represent
the year of manufacture (i.e. “15” refers to 2015). The last six digits is a unique identifier. All eight numbers create the
serial number of the device.
