Note: In order to prevent feedback while placing the hearing amplifiers in
your ear, only switch them on once you have placed them in your ear and
behind your ear.
Use the volume control to adjust the volume to the desired level so that you
can hear sounds clearly and distinctly.
• If you hear a slight whistling sound when wearing the hearing
amplifier, check that your earplug is fitted properly in your ear. If it is
not snug enough, use a different earplug.
• The hearing amplifier does not heal an existing hearing impairment,
but it does improve hearing and speech understanding.
