Instruction for Use
Wearing option spectacles
When selecting a suitable wearing option
(spectacles front and extension tips),
please consider the various sizes! Incorrect
use and selection of the sizes of the wearing
option can lead to skin irritation, pressure
points and pain.
Please make absolutely sure that the
spectacles of the
contact star evo1
is
positioned correctly on the head and that the
conductor plate of the bone conduction receiv-
er rests against the head. Please make sure that
the conductor plate is touching the skin.
• Hair between the conductor plate and the
skin may reduce transmission considerably.
• Poor contact with the skin and a high volume
may cause feedback.
Select the most comfortable volume for you
by rotating the volume control
. The volume
becomes "louder" when you turn the volume
control forward. The volume becomes "lower"
when you turn the volume control backward.
Important notes on operating the
hearing spectacles:
Switch off the device by using the O-T-M switch
, put on your hearing spectacles, select
volume level low and switch the device back on.
Select the most pleasant volume level only after
switching on and checking volume of device!
Special care must be taken to ensure that
the conductor plate of the bone conduction
receiver
is firmly seated against the ma-
stoid bone. Partial or weak contact will cause
feedback (whistling).
