On Using the Headphone
Road safety – 
Do not use headphone while driving, cycling, or 
operating any motorized vehicle. It may create a traffic hazard and is 
illegal in some areas. It can also be potentially dangerous to play your 
headphone at high volume while walking, especially at pedestrian 
crossings. You should exercise extreme caution or discontinue use in 
potentially hazardous situations.
Preventing hearing damage –
 Avoid using headphone at high 
volume. Hearing experts advise against continuous, loud and 
extended play. If you experience a ringing in your ears, reduce the 
volume or discontinue use.
On Maintenance
Make sure to disconnect the power cord before cleaning the 
computer.
Avoid rubbing the LCD screen as this can damage the screen. Use a 
soft, dry cloth to wipe the LCD screen.
Clean the computer with a soft cloth lightly moistened with a mild 
detergent solution. Do not use any type of abrasive pad, scouring 
powder or solvent, such as alcohol or benzine.
