I.IMPORTANT SAFETY INSTRUCTIONS
1. CONTRAINDICATION
The device should not be used in the following situations:
- Patients with chronic suppurative otitis media (CSOM),
congenital ear atresia, or any type of ear discharge
- Anyone under 36 months old
2. WARNINGS
- Keep small parts (hearing instrument, ear domes, battery or
other detachable parts) that can be swallowed out of children’s
reach. Dropping, immersing in liquid, exposure to strong
electromagnetic fields or excessive heat will damage the
hearing aids. Remove devices prior to any type of X-ray, MRI,
or CT scan. If parts become stuck in the ear canal, seek
medical assistance - do not attempt to remove by yourself.
3. Notice
- Do not use at high volume for extended periods of time - ear
injury can result.
- If you experience any pain or strong discomfort using the
devices, remove and consult a doctor.
- Routine maintenance to keep the device clean is required.
Ensure that ear domes are free of debris and moisture at all
times.
- Avoid shocks or dropping the product.
- Do not store or use the product in environments of high
humidity or temperature (such as sauna room), to avoid
damage.
- Batteries should be properly recycled and not disposed in the
trash.
- Keep the devices away from small children. Injury or damage
may result.
- Do not set volume levels too high. Listening with high-output
devices for extended periods at high volume levels can cause
further hearing damage.
- Do not share your hearing aids with others. Using a hearing
aid configured for someone else can result in hearing damage
or injury.
- Monitor for any unusual skin reaction. If you notice any
allergic reaction (itchiness, swelling, or rash), stop wearing the
hearing aids and consult a medical specialist.
- Do not touch the hearing aids to any type magnet or magne-
tized object. Your hearing aids are delicate electronic instru-
ments and may be damaged by contact with strong

magnetic fields.
- Do not attempt to open or repair the devices yourself.
Damage can result and will void the warranty.
- Do not store your devices in a hot/humid locations. You
should never leave your hearing aids near heating appliances
or in direct sunlight.
- Do not leave your hearing aids in the car as inside tempera-
tures can reach dangerous levels which could damage the
devices.
- Do not use the hearing aids together with a cell phone
earpiece directly - excessive noise and distortion may result.
Instead, use via Bluetooth pairing with your cell phone. Radio
wave emissions from mobile phones can cause noise in the
hearing aids or result in reduced volume.
- Please contact the MANUFACTURER:
• For assistance, if needed, in setting up, using or maintaining
your devices or to report any unexpected operation or events.

1. Daily maintenance
It is important to keep your devices clean and dry. On a daily
basis, wipe them clean using a soft cloth or tissue.
V. MAINTENANCE AND CLEANING
All data in this manual, such as service time, charging time,
continuous working time, and charging times are derived from
our internal laboratory testing and meant for reference purpos-
es only. Your exact usage and times may differ depending on
various conditions and use patterns. It is a normal phenome-
non to hear some high-pitched whistling or buzzing when the
hearing aid is at a high volume level and not fitted well into the
ear as a result of mic feedback. If this occurs, lower the volume
and adjust the hearing aid within the ear. Also check to make
sure you are wearing the best size ear domes to ensure a
proper fit in the ear canal, as this may also induce some minor
feedback if not snug in the ear.
To avoid potential damage from excess humidity or
perspiration, the use of a drying kit is also recommended.
2. Care and maintenance
When not in use, store in a secure area away from small
children and pets.
Do not place hearing aids or charging case near high-tem-
perature areas such as stoves or direct sunlight.
Do not leave the devices in a humid place for a long time,
such as bathroom.
Take care not to poke the microphone holes with any sharp
objects to avoid damage.
Do not disassemble or attempt any repairs by yourself. Doing
so will void your warranty.
3. Cleaning
1) Cleaning the ear tips
Remove any earwax buildup using the
enclosed tool. Wipe clean with a tissue or soft cloth.
2) Cleaning Tool
Use a soft cloth or tissue to wipe any moisture, perspira-
tion, or debris from the surface of the tool.
4.When the hearing aid and case is not functioning properly,
please check the “troubleshooting guide”. If none of the
solutions work, please contact our after-sales service team.

- Keep your hearing aids clean. Extreme temperatures (heat or
cold), moisture, and foreign substances can result in poor
performance.
- Use the cleaning brush tool or soft cloth to clean debris from
around the buttons, microphones, and charging contacts;
inspect the receiver, ear tips, and charging case regularly.
- Never use water, solvents, cleaning fluids or oils to clean your
hearing aids.
- Charging contacts should always be kept clean and dry.
- Always store your hearing aids in the charging case when not
in use or cleaning.
Charging Case Care
- Keep your charger clean. Heat, moisture and foreign mater-
ials can result in poor performance.
- Using the provided cleaning brush keep the charging ports
clear of debris.
- Do not use water, solvents or cleaning fluids to clean the
charging ports.
- Keep lid closed as much as possible to avoid dust and debris
build up.
- Store your charger in a clean and dry location, i.e. a dresser
or shelf rather than the bathroom or kitchen.
- To ensure the longest life of your rechargeable hearing aids
batteries and the batteries in the charger:
- Fully charge hearing aids batteries every night.
Service and Repair
If, for any reason, your hearing aid does not operate
properly, do NOT attempt to fix it yourself. Not only are you
likely to violate any applicable warranties or insurance, you
could easily cause further damage.Should your hearing
aid fail or perform poorly, check the Troubleshooting Guide on
the next page for possible solutions. If problems
continue, contact us or your hearing professional for advice
and assistance. Many common problems may be solved right
in your hearing professional’s office or clinic.

It will take practice, time, and patience for your brain to adapt
to the new sounds that your hearing aids provide. Hearing is
only part of how we share thoughts, ideas and feelings.
Reading lips, facial expressions, and gestures can help the
learning process and add to what amplification alone may
miss.
Please review the following simple communication tips:
For You
- Move closer to and look at the speaker
- Sit face-to-face in a quiet room if possible
- Try out different locations to find the optimal places to
listen
- Minimize distractions
- Background noises may be frustrating at first; remember,
you have not heard them for a while
- Let others know what you need; keep in mind that people
cannot “see” your hearing loss

- Develop realistic expectations of what your hearing aids
can and cannot do
- Better hearing with hearing aids is a learned skill combin-
ing desire, practice, and patience. You will learn and adjust, it
just takes a little time. Remember to be patient with yourself.
For Your Family and Friends
Your family and friends are also affected by your hearing loss.
Request that they:
- Get your full attention before beginning to speak
- Look at you or sit face-to-face
- Speak clearly and at a normal rate and level; shouting can
actually make understanding more difficult
- Rephrase rather than repeat the same words; different
words may be easier to understand
- Minimize distractions while speaking
