Your hearing is limited while you are using the device. Therefore, the device
•
should not be used while one is driving a vehicle or using a power tool. Do
not use the device in situations that require unrestricted hearing.
Do not use the device in combination with another device connected to the
•
electrical network, such as a hair-dryer, curling iron, or electric razor.
Handle the device with care:
•
Protect the device from moisture, and do not use it in a damp
•
environment.
Protect the device from impacts, vibration, falling, pressure, and
•
bending and other deformation.
Protect the device from dust, dirt, freezing, heat, extreme changes in
•
temperature, and direct sunlight.
Clean the device carefully after each use. If the optical fibers become
•
dirty or are scratched, their luminosity may be reduced.
Do not use the device if the device itself or the cables, optical fibers, or
•
earplugs are damaged. Always check before use that all parts of the
device are undamaged.
The device is intended for use by one person only. If, however, you share the
•
device with someone, pay attention to the hygiene of the earplugs.
Do not try to open, repair, or adjust the device yourself. If you open the
•
device, the warranty becomes void and safe operation of the device can no
longer be guaranteed.
After the device has been removed from use, take it to a collection point for
•
waste electrical and electronic equipment. See ‘Removing the device from
use’.
USING THE DEVICE
USING THE DEVICE
If any third party makes any modifications to the device itself or to its
•
software, the warranty becomes void.
Recharge the device by using a charger intended for the charging of medical
•
devices (a suitable USB cable or a USB socket charger, not included in the
delivery).
Recommendations for use
Use the device regularly, every day at the same hour, for at least 2–4 weeks.
The longest treatment duration allowed is 12 minutes at a time. For most people,
the most suitable treatment time is in the morning. The effects and impact of the
device vary greatly from one individual to another.
If you wish, you can shorten the treatment time by removing the earplugs from
your ears in the middle of the treatment. Switch off the device by depressing the
power button for two seconds before removing the earplugs. Alternatively, you can
adjust the duration and efficacy of the treatment via the MyValkee interface; see
the section ‘Adjustment of treatment settings’.
If you notice side effects after several treatments, try changing the treatment time
from morning to closer to noon and/or adjusting the treatment settings. If the side
effects continue, discontinue treatment and contact the device’s manufacturer or a
physician.
Recharge the device occasionally even when it is not in regular use. This
increases the battery life.
Take care of the hygiene of the device, particularly if several people use the same
device.
Also protect the device from dirt, dust, humidity, and impacts. Valkee carrying bags
suitable for this purpose are available separately from Valkee Oy.
