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 6 years 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 amplifiers.
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.
Warning
Read all the information in this instruction manual and any other
literature included in the box before using the device.
Warning

- 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 amplifiers with others. Using a hearing
amplifier 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
amplifiers and consult a medical specialist.
- Do not touch the hearing amplifiers to any type magnet or magne-
tized object. Your hearing amplifiers are delicate electronic
instruments 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 amplifiers near heating appliances or in
direct sunlight.
- Do not leave your hearing amplifiers in the car as inside tempera-
tures can reach dangerous levels which could damage the devices.
- Do not use the hearing amplifiers 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 amplifiers 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
Specific warnings / statements
Keep small parts away from and out of children´s reach to avoid
accidental ingestion
Warning not to use in explosive or oxygen-enriched atmospheres, as
doing so may damage the device
Warning that it should only be used by intended person as using
hearing amplifiers designed for someone else may result in hearing
damage

II. DO NOT USE IF ANY OF THE FOLLOWING APPLY
TO YOU:
1) Congenital atresia of external ear or deformity of any part of the
ear canal
2) Deafness is unstable, and the degree of hearing loss often
fluctuates
3) Persistent headaches, dizziness, earaches, tinnitus or other
symptoms that are not suitable for adaptation
4) Sudden onset of hearing loss within the past 3 months; rapid
progressive deafness; unilateral hearing loss or other acute ear
disease;
5) Effusion (secretions/discharge) in the ear and/or frequent
purulence (pus)
6) Central deafness (central nervous system) or non-organic
deafness
7) Patients with acute otitis externa and tympanitis
8) Patients with acute and chronic suppurative otitis media (in the
period of purulent infection)
9) Patients who are allergic to the materials of this product

1. Do not immerse the hearing amplifier in any liquid. Remove the
hearing amplifier before swimming or bathing. After swimming or
washing, wait for the ear canal to dry before wearing the hearing
amplifier.
2. After removing the hearing amplifier at night, it should be placed
in a case with a desiccant if possible, protected from light, high
temperature and high humidity environment.
3. The external surfaces of the hearing amplifier should be kept
clean, and earwax in the ear domes should be cleaned out daily
4. Applicable objects: Suitable for people with air-conducting
hearing loss of about 30-50dB
5. When you do not use hearing amplifiers, please charge the
product regularly to avoid battery damage; the recommended
charging time interval of hearing amplifiers is ≤28 days

detection on the operation status of the hearing amplifier. When the
hearing amplifier is removed, it will automatically enter the standby
status. When you place the hearing amplifier in the ear, it will
automatically turn on.
L marking for left hearing amplifier.R marking for right hearing amplifier.
Notes:
After the ear dome is installed, pull the ear dome gently to see if it
is firmly installed and ensure the ear dome does not fall off easily.

5.【TURN ON/TURN OFF】
Turn On: Take the hearing amplifier out of the charging case, the
hearing amplifier will enter the standby status. The hearing amplifi-
er will turn on automatically in 3 seconds when you wear the
hearing amplifier correctly in the ears.
2. Before the hearing amplifier is appropriately secured, it may give
out the creak sound, which is a normal phenomenon. The creak
sound can be used as a reference to determine whether the
hearing amplifier is secured. If the hearing amplifier gives out
squeaking, please check if it is taken on correctly; if so, but the
squeaking remains, please replace with the other set of ear dome.
When the hearing amplifier is not in use, please turn it off without
delay.
3. When the hearing amplifier is not functioning properly, please
check the “Troubleshooting Guide”. If none of the solutions work,

To increase the volume, turn the volume control towards the "+"
direction (forwards). To decrease the volume, turn the volume
control towards the "-" direction (backwards).
