If you wear bifocals, always have vision tests performed before your first
use of your Toshiba Pocket PC e830, and then periodically thereafter, to
protect against eyestrain and possibly physical discomfort as well.
Always keep your glasses, contact lenses, and the LCD as clean as pos-
sible.
Always take frequent rest breaks, and relax the focusing system of the
eyes by looking at distant objects (objects located at a distance greater
than 15 feet).
If you experience vision-related problems, including (but not limited to)
eyestrain, irritation or pain, blurred or double vision, excessive tears or dry
eyes or excessive blinking or squinting, always consult a vision-care spe-
cialist to protect your eyesight.
Prevention of physical discomfort
When Toshiba Pocket PCs are to be used under the less-than ideal condi-
tions that may sometimes be encountered in the field, prudent precau-
tions must be taken to prevent physical discomfort to the body or to the
hands, wrists and arms. Physical discomfort can be avoided by taking fre-
quent rest breaks and by periodically initiating changes in activity, envi-
ronment or work-tempo.
Prevention of physical discomfort to the body
To prevent physical discomfort to the back, neck, shoulders and other
parts of the body, even while using your Toshiba Pocket PC e830 under
sub optimum field conditions, the following work practices should always
be observed:
In order to avoid exposing the body to physical discomfort, always initiate
periodic changes in work-tempo and take periodic breaks when working
with your Toshiba Pocket PC e830 over an extended period of time.
Always avoid any awkward working positions that could cause discomfort
or stress to the back, neck, or shoulders.
Always take time to stretch and exercise your body periodically, through-
out the workday, to avoid experiencing muscular and skeletal aches and
pains.
Always avoid sitting in one position for long periods of
time, by periodically performing alternate tasks or by peri-
odically moving to a different environment.
