Listening Safely
Set the headphone volume to the lowest setting before listening. After you begin
listening, adjust the volume to a comfortable level.
Do not listen at extremely high volume levels. Extended high-volume listening
can lead to permanent hearing loss.
If you connect the transmitter to an audio source headphone jack, set the
audio source’s volume to the middle position. Then adjust VOLUME on the
headphones to the desired level.
Turn off the headphones before turning off the transmitter. This prevents you
hearing a loud click that may be generated when you turn off the transmitter.
