WEARING THE DEVICE (cont’d):
The diagram below shows a properly worn
Okara
Rechargeable BTE Personal Sound Amplifier in the left ear.
IN CASE OF FEEDBACK OCCURRED:
Feedback is created by the noise produced from the device
speaker travelling to the back of the amplifier unit . To
remove feedback, you should fit the device properly into
your ear by adjusting its ear tip to leave no gaps for feedback
travelling between your ear and the device. Try changing
to the ear tip that can provide you comfort fit for hearing
better. Correctly setting sound volume appropriate to your
hearing requirement is primary important for eliminating
feedback.
