❖

Avoid bending, arching, or twisting your wrists. Keep 
them in a relaxed, neutral position while typing.

❖

Exercise your hands, wrists and arms to improve 
circulation.

The key to avoiding discomfort or injury from strain is to 
vary your activities. If possible, schedule a variety of tasks 
into your working day. Finding ways to break up the routine 
can reduce stress and improve your efficiency.

❖

Take frequent, short breaks to change position, stretch 
your muscles, and relieve your eyes. A break of two or 
three minutes every half hour is more effective than a 
long break after several hours.

❖

Avoid performing repetitive activities for long periods. 
Intersperse such activities with other tasks.

❖

Focusing your eyes on your computer screen for long 
periods can cause eyestrain. Look away from the 
computer frequently and focus your eyes on a distant 
object for at least 30 seconds.

Your LCD display has a brightness approaching that of a TV 
device. We recommend that you adjust the brightness of your 
LCD to a comfortable level to prevent possible strain on your 
eyes.

Your computer is designed to optimize safety, minimize 
strain, and withstand the rigors of portability. However, you 
should observe certain precautions to further reduce the risk 
of personal injury or damage to the computer.
