Kinesis KB510USB USB Contoured Ergonomic Keyboards - Manual (Page 20)

Positioning
When you use your keyboard, your wrists should be at approximately the same height as your
elbows, with your forearms parallel to the floor. Adjust the height of your chair up or down to
allow your feet to rest flat on the floor, with your knees bent approximately 90° and your
thighs parallel to the floor. If the height of your work surface is not adjustable, you may need
to adjust your chair to accommodate the work surface instead. You can add a foot rest, if
necessary. Finally, you should sit close enough to your keyboard that your upper arms rest
comfortably at your sides, with your elbows tucked in.
Starting to type
To start typing, place your fingers on the Kinesis home row keys (the blue key caps). Relax
your right thumb over the Space key and your left thumb over Backspace. Raise your palms
slightly above the palm rests while typing. This provides the necessary mobility for your
hands so that you can comfortably reach all of the keys.
Now begin typing, starting from a position on the home row. When you pause to think or
compose, you can reduce physical stress by resting your hands on the Kinesis keyboard’s
padded palm rests.
Important: You should not expect to reach all of the keys on the keyboard without moving
your hands from a stationary position on the palm rests. Many users prefer to move their arms
slightly to press the most distant thumb keys, or to use their index fingers.
