Billing clerks frequently:

• Sit for long periods of time.
• Repeat the same movements.
• Use their hands to handle, control, or feel objects, tools, or controls.

It is important for billing clerks to be able to:

• See details of objects that are less than a few feet away.
• Understand the speech of another person.
• Speak clearly so listeners can understand.

It is not as important, but still necessary, for billing clerks to be able to:

• Make fast, repeated movements of fingers, hands, and wrists.
• Use stomach and lower back muscles to support the body for long periods without getting tired.
• See details of objects that are more than a few feet away.
• Focus on one source of sound and ignore others.
