Trouble Shooting

please clean and maintain the
charging boxes regularly.
During the use of hearing aids, earwax
(cerumen) produced by the ears will
accumulate in the ear canal and the sound
hole of the hearing aid. A large amount of
accumulated earwax will affect the use effect
of the hearing aid, so please clean your ear
canal and maintain the hearing aid regularly.
Remove the ear domes from the hearing aid,
clean the earwax with a cleaning cloth
orwash the ear domes with clean water, and
wipe the ear domes dry. Please make
surethere are no water droplets left. lf there
are tools like blowing balloons, you can
useblowing balloons to dry the water droplets.

Hearing Aid Maintenance and charging boxes

Remark: Special drying box needs to be purchased separately.
Please clean your hearing aid with a dry soft cloth.
When wiping or cleaning the hearing aid, please do it on a soft desktop
(for example,put a soft towel on the desktop) to avoid damage caused
by accidental falling of the hearing aids and charging box.
Remember: do not use any liquid to clean the hearing aid and
c) Clean Hearing Aid and charging box
Please put the hearing aid in a special drying box to keep away
from damaging moisturebefore sleeping every night for
extending the life of the hearing aid.

Hearing Aid Maintenance
a) Dehumidification :
Any form of moisture is influential for hearing aid, dehumidification
can extend the life ofthe hearing aid. Avoid using or storage in humid
environment, and please dry the hearingaid on a regular basis.
b) Water Prevention:
Avoid hearing aid contact with water. Remove the hearingaid when
you are swimming, taking a shower, washing yourhair, washing your
face. If hearing aid accidentally falls intothe water, do not use dryer to
dry it. You can dry it with a softclean cotton cloth and put it in a
ventilated environment.Ifa failure occurs, please contact with your
local audiologist or contact with the stafffrom customer service
center.
c) High Temperature Prevention:
Never exposing hearing aids on extreme temperatures orprolonged
exposure to sunlight.
d) Falling Prevention:
Please do not drop your hearing aids or knock them against hard
e)Precautions for Electromagnetic Compatibility
- Classification by anti electric shock type: Internal power supply
equipment.
- Classification according to the degree of protection against electric
shock: Type B application part.
- Classification by operation mode: Continuous operation equipment.
Notes: The Hearing Aid conforms to IEC60601-1-2 EMC and IEC
60118-13 requirements.
It is the responsibility of the user to ensure the electromagnetic
compatibility environment of the instrument to function properly.
User must install and operate the device based on the provided EMC
information.
It is recommended to evaluate the electromagnetic environment
before using the instrument to ensure that the surrounding
environment will not cause strong electromagnetic interference to
the instrument, otherwise it may interfere with the normal operation
of the equipment.
19 20

Instructions for use: The ME EQUIPMENT or ME SYSTEM is suitable for
healthcare environments and so on.
Warning: Only the power adapter and battery approved by manufac-
turer can be used. In order to avoid damage to the instrument, please
do not change the charging parts.
Even if other devices meet the emission requirements of the
corresponding national standards, the Hearing Aid may still be
interfered by other devices.
Warning:In the home environment, this equipment may cause radio
interference, so protective measures should be taken. It is forbidden
to use the equipment near strong radiation source (such as unshield-
ed RF source), otherwise it may interfere with the normal operation of
the equipment.
Warning: Portable or mobile RF communication device might
influence the performances of Hearing Aid, please avoid strong
electromagnetic disturbance while using, such as close to the
Hearing Aid, microwave oven, etc .
Warning: Use of this equipment adjacent to or stacked with other
Warning: Portable RF communications equipment (including
peripherals such as antenna cables and external antennas) should
be used no closer than 30 cm (12 inches) to any part of the Hearing
Aid, including cables specified by the manufacturer. Otherwise,
degradation of the performance of this equipment could result.
Warning:Use of accessories, transducers and cables other than
those specified or provided by the manufacturer of this equipment
could result in increased electromagnetic emissions or decreased
electromagnetic immunity of this equipment and result in
improper operation.”
Warning:Do not approach active high-frequency surgical
equipment and magnetic resonance imaging systems in radiofre-
quency shielded rooms, where the intensity of EMI disturbances is
high.
Warning: Do not near active HF surgical equipment and the RF
shielded room of an ME system for magnetic resonance imaging,
where the intensity of EM disturbances is high.
Warning: Make sure that all electrical accessories connected to the
Hearing Aid must comply with IEC 60601-1, if in doubt, consult the
21 22

technical service department or your local representative.
Warning: No unauthorized modification allowed of the ME EQUIP-
MENT.
According to the design purpose, the equipment complies with EMC
regulations. Including the allowable electromagnetic interference
level and necessary electromagnetic shielding performance of the
electronic equipment specified by laws and regulations.
The complete elimination of electromagnetic interference is almost
impossible unless all equipment that may produce high-frequency
signals are excluded. Although some high-frequency equipment itself
meets the requirements of EMC regulations, it is impossible to
determine whether the radio signal generated by its high-frequency
transmitter will affect the normal operation of the equipment when it
works with considerable power near the equipment order to ensure
the electromagnetic compatibility of the equipment, the equipment
needs to be installed, debugged and used according to the attached
documents. In case of such situation, please contact the personnel of
the company for solution.
This equipment generates, uses, and can radiate RF energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
- Operate in strict accordance with the instructions of the Hearing Aid
instruction manual to ensure that the device is not subject to
electromagnetic interference.
- Keep other devices away from this device to reduce the effects of
electromagnetic interference.
- Reorient or relocate the receiving antenna. The effect of electromag-
netic interference can be mitigated by adjusting the relative
position/mounting angle between the device and other devices.
- Reduce electromagnetic interference by changing the wiring location
of other device power/signal cables.
- Reduce electromagnetic interference by changing the power path of
other devices.

The Hearing Aid uses RF energy only
for its internal function. Therefore, its
RF emissions are very low and are
not likely to cause any interference in
nearby electronic equipment.
The Hearing Aid suitable for use in
all establishments, including
domestic establishments and those
directly connected to
the public low-voltage power supply
network that supplies buildings used
for domestic purposes.

Recommended separation distances between portable and
mobile RF communication the equipment
The Hearing Aid is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of The Hearing Aid can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the Hearing Aid as recommended below, according to the maximum output power of the
communications equipment.
For transmitters rated at a maximum output power not listed above, the recommended separation distance
in met ers (m) can be determined using the equation applicable to the frequency of the transmitter,
where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1 : At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 : These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
