Sitting at your computer
Avoid bending, arching, or angling your wrists. Make 
sure that they are in a relaxed position when you type.
Do not slouch forward or lean far back. Sit with your back 
straight so your knees, hips, and elbows form right 
angles when you work.
Take breaks to stand and stretch your legs.
Avoid twisting your torso or neck.
Avoiding discomfort and injury from repetitive 
strain
Vary your activities to avoid excessive repetition.
Take breaks to change your position, stretch your 
muscles, and relieve your eyes.
Find ways to break up the work day, and schedule a 
variety of tasks.
Preparing power connections
Protecting from power source problems
During a power surge, the voltage level of electricity coming 
into your computer can increase to far above normal levels and 
cause data loss or system damage. Protect your computer and 
peripheral devices by connecting them to a surge protector
which absorbs voltage surges and prevents them from 
reaching your computer.
An uninterruptible power supply (UPS) supplies battery power 
to your computer during a power failure. Although you cannot 
run your computer for an extended period of time with a UPS, 
a UPS lets you run your computer long enough to save your 
work and shut down your computer normally.
Warning
High voltages can enter your computer through both the power cord and 
the modem connection. Protect your computer by using a surge protector. If you 
have a telephone modem, use a surge protector that has a modem jack. If you 
have a cable modem, use a surge protector that has an antenna/cable TV jack. 
During an electrical storm, unplug both the surge protector and the modem.
