IMPACT PC USER’S MANUAL
Placement Tips
Your IMPACT PC should be set up correctly according to this user manual,
and your own comfort and ergonomic needs. Please refer to the following
tips to create a comfortable and healthy working environment for you:
1. Adjustable Seat: If you plan to use your IMPACT PC for extended periods,
select a highly adjustable office chair with a five-pronged base. The seat
and chair back should be adjustable, while you’re sitting in the chair, for
height and tilt, and forward/backward positioning. In addition, the lumbar
area of your back should be supported by chair adjustments or a cushion.
Arm rests should conform to your elbow height and shoulder width and
should be used for support. For maximum comfort, vary positions frequently
throughout the day, observe good posture when seated, and keep your
head centered over your shoulders.
2. Suitable monitor level: Position your computer so that it is at arm's length
away and the top third of the monitor viewing area is at eye level. This helps
prevent eye and neck strain. To further reduce eye strain, close your eyes
and/or refocus on something other than your computer screen at least twice
an hour. Most monitors come standard with a detachable tilt-and-swivel
base and an adjustable, rear-mounted foot, which will allow you to position
the monitor exactly where you want it.
3. Anti-glare coating: Some monitor screens are constructed with a special
anti-glare coating, which minimizes reflections that cause eyestrain and
discomfort. To further reduce eyestrain, close your eyes and/or refocus on
something other than your computer screen at least twice an hour.
4. Adjustable task lighting: When room lighting is dimmed, there may be
insufficient light on documents or reference materials for comfortable
reading. A well-lit room or a few adjustable, directional task lights will allow
you to see your monitor screen and other materials clearly, causing the least
amount of strain on your eyes.
5. Appropriate position for wrist rest: Keep your wrists straight and your
forearms parallel to the floor while you are typing. If you use a wrist rest, use
it only briefly while resting. Do not rest your hands on the table or on the
wrist rest as you are typing. During long periods of typing, taking frequent
breaks is recommended.
