NEC PowerMate eco Getting Started Guide 15
Check the following:
Keep your body in a relaxed yet upright position. The backrest of your chair should support
the inward curve of your back.
Use the entire seat and backrest to support your body. Tilt the backrest slightly backwards.
The angle formed by your thighs and back should be 90° or more.
Your seat depth should allow your lower back to comfortably contact the backrest. Make
sure that the backs of your lower legs do not press against the front of the chair.
Extend your lower legs slightly so that the angle between your thighs and lower legs is 90°
or more.
Place your feet flat on the floor. Only use a footrest when attempts to adjust your chair and
workstation fail to keep your feet flat.
Be sure that you have adequate clearance between the top of your thighs and the underside
of your workstation.
Use armrests or forearm supports to support your forearms. If adjustable, the armrests or
forearm supports should initially be lowered while all the other adjustments discussed in
this document are made. Once all these adjustments are completed, raise the armrests or
adjust the forearm supports until they touch the forearms and allow the shoulder muscles to
relax.
Adjust Your Input Devices
Follow these points in positioning your keyboard and mouse.
Position your keyboard directly in front of you. Avoid reaching when using your keyboard
or mouse.
If you use a mouse, position it at the same height as the keyboard and next to the keyboard.
Keep your wrists straight and use your entire arm when moving a mouse. Do not grasp the
mouse tightly. Grasp the mouse lightly and loosely.
Adjust the keyboard height so that your elbows are near your body and your forearms are
parallel to the floor, with your forearms resting on either armrests or forearm supports, in
the manner described previously. If you do not have armrests or forearm supports, your
upper arms should hang comfortably at your sides.
Adjust your keyboard slope so that your wrists are straight while you are typing.
