Concerning Road Safety
Do not use headphones while driving, cycling, or operating any

many areas. It can also be potentially dangerous to play your
headsets at high volume while walking, especially at pedestrian
crossings. You should exercise extreme caution or discontinue
use in potentially hazardous situations.
Preventing hearing damage
Do not use headphones at high volume. Hearing experts advise
against continuous, loud and extended play. If you experience a
ringing in your ears, reduce volume or discontinue use.
Caring for others
Keep the volume at a moderate level. This will allow you to hear
outside sounds and to be considerate to the people around you.
Taking Care of Your Walkman
•Do not expose the Walkman to extreme temperatures, direct
sunlight, moisture, sand, dust or mechanical shock. Never
leave the Walkman in a car parked in the sun.
•Do not wind the headphones cord around the Walkman.
The buttons may be kept pressed, causing unnecessary battery
usage.
•Prolonged use may contaminate the tape head. If sound
drop-out or excessive noise occurs, clean the head and tape
path with alcohol.
•Clean the headphones plug periodically for optimum sound.
