Getting Started
Work habits
A key to avoiding discomfort or injury from repetitive strain is to vary your
activities. If possible, schedule a variety of tasks into your workday. If you
must spend long periods at the computer, finding ways to break up the
routine can reduce stress and improve your efficiency.
■ Sit in a relaxed posture. Good positioning of your chair and equipment
as described earlier can reduce tension in your shoulders or neck and
ease back strain.
■ Vary your posture frequently.
■ Occasionally stand up and stretch or exercise briefly.
■ Exercise and stretch your wrists and hands a number of times during
the day.
■ Frequently, look away from the computer and focus your eyes on a
distant object for several seconds, for example 30 seconds every
15 minutes.
■ Take frequent short breaks instead of one or two long breaks, for
example, two or three minutes every half hour.
■ Have your eyes examined regularly and visit a doctor promptly, if you
suspect you might be suffering from a repetitive strain injury.
A number of books are available on ergonomics and repetitive strain injury
or repetitive stress syndrome. For more information on these topics or for
pointers on exercises for such stress points as hands and wrists, please
check with your library or book vendor. Also refer to the computer’s
Instruction Manual for Safety & Comfort.
Connecting the AC adaptor
Attach the AC adaptor when you need to charge the battery or you want to
operate from AC power. It is also the fastest way to get started, because
the battery pack will need to be charged before you can operate from
battery power.
The AC adaptor can be connected to any power source supplying from
100 to 240 volts and 50 or 60 hertz. For details on using the AC adaptor to
charge the battery pack, refer to Chapter 6, Power .
Use only the AC adaptor supplied as an accessory. Other AC adaptors
have different voltage and terminal polarities and use of them may produce
heat and smoke or even result in fire or rupture.
