Listening Safely
To protect your hearing, follow these guidelines when you use
headphones.
•
Insert the headphone plug into the HEADPHONE jack and set
the volume to zero before putting on your headphones. With
the headphones on, adjust the volume to a comfortable level.
•
Avoid increasing the volume once you set it. Over time, your
sensitivity to a volume level decreases, so volume levels that
do not cause discomfort might damage your hearing.
•
Avoid or limit listening at high volume levels. Prolonged
exposure to high volume levels can cause permanent hearing
loss.
Traffic Safety
Wearing headphones while operating a motor vehicle or riding a
bicycle is very dangerous and illegal. Do not operate any vehicle
while listening to the EZ Scan-SD with headphones or
earphones.
