the Mail Matrix.
When seated at the main operator station or keying station:
• Maintain an upright body posture. Avoid the tendency to slump in your
chair. The angle between your torso and thighs should always be 90
degrees.
• Adjust the seat position on your chair so that your elbow, when held at a 90-
degree angle at your side, is approximately 1½ inches below the top of the
work surface. For your comfort, we recommend use of a specially-designed
OPEX ergonomic desk chair to ensure proper posture and seat position.
• Occasionally change the angle of your posture for greater comfort.
• If possible, avoid operating the machine for longer than a single 8-hour
shift.
