The majority of hearing aid users have a hearing
loss for which a deterioration in hearing is not
to be expected with regular use of a hearing aid
in everyday situations. Only a small group of
hearing aid wearers with hearing loss, may be
at risk of deterioration in hearing after a long
period of use.
Never wash the microphone inputs. Doing so could
cause it to lose its special acoustic features.
Cables and cords wrapped around the neck may
cause strangulation. Do not leave the device
and its components unattended with children,
individuals with cognitive impairment or pets.
Product Safety
These hearing aids are water resistant but not
waterproof. They are designed to withstand
normal activities and occasional accidental
exposure to extreme conditions. Never immerse
your hearing aids in water. These hearing aids
are not specifically designed for extended
periods of water submersion, eg. activities
such as swimming or bathing. Always remove
your hearing aids before these activities, as the
hearing aids contain sensitive electronic parts.

All-Day Clear
Protect your hearing aids and charging
accessories from heat (never leave near a
window or in the car). Never use a microwave or
other heating devices to dry your hearing aids
and charging accessories (due to risk of fire or
explosion).
Eartips should be changed every three to six
months or when it becomes stiff or brittle. This is to
prevent the eartip from detaching from the earpiece
during insertion into or removal from the ear.
Do not drop your hearing aids and charging
accessories. Dropping onto a hard surface
can damage your hearing aids and charging
accessories.
The hearing aids and charging case have to be
dry before charging. Otherwise the charging
reliability cannot be guaranteed.
In most cases, infrequent use of hearing aids
does not provide full benefit. Once you have
become accustomed to your hearing aids, wear
your hearing aids everyday all day.
Your hearing aids use the most modern
components to provide the best possible sound
quality in every listening situation. However,
communication devices such as digital mobile
phones can create interference (a buzzing sound)
