Understanding Ergonomics
Here are some tips for setting up a healthy work environment.
Keyboard and Trackpad
When you use the keyboard and trackpad, your shoulders should be relaxed. Your 
upper arm and forearm should form an angle that is slightly greater than a right angle, 
with your wrist and hand in roughly a straight line.

62Chapter 5   Last, but Not Least
Use a light touch when typing or using the trackpad and keep your hands and fingers 
relaxed. Avoid rolling your thumbs under your palms.
Change hand positions often to avoid fatigue. Some computer users might develop 
discomfort in their hands, wrists, or arms after intensive work without breaks. If you 
begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a 
qualified health specialist.
External Mouse
If you use an external mouse, position the mouse at the same height as the keyboard 
and within a comfortable reach.
Chair
An adjustable chair that provides firm, comfortable support is best. Adjust the height 
of the chair so your thighs are horizontal and your feet are flat on the floor. The back of 
the chair should support your lower back (lumbar region). Follow the manufacturer’s 
instructions for adjusting the backrest to fit your body properly.

Chapter 5   Last, but Not Least63
You might have to raise your chair so that your forearms and hands are at the proper 
angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you 
can use a footrest with adjustable height and tilt to make up for any gap between the 
floor and your feet. Or you can lower the desktop to eliminate the need for a footrest. 
Another option is to use a desk with a keyboard tray that’s lower than the regular 
work surface.
Built-in Display
Adjust the angle of the display to minimize glare and reflections from overhead lights 
and windows. Do not force the display if you meet resistance. The display is not meant 
to open past 130 degrees.
You can adjust the brightness of the screen when you take the computer from one 
work location to another, or if the lighting in your work area changes.

Regulatory Compliance Information
FCC Compliance StatementThis device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:  (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. See instructions if interference to radio or television reception is suspected.
L‘utilisation de ce dispositif est autorisée seulement aux conditions suivantes: (1) il ne doit pas produire de brouillage et (2) l’utilisateur du dispositif doit étre prêt à accepter tout brouillage radioélectrique reçu, même si ce brouillage est susceptible de compromettre le fonctionnement du dispositif.
Radio and Television InterferenceThis computer equipment generates, uses, and can radiate radio-frequency energy. If it is not installed and used properly—that is, in strict accordance with Apple’s instructions—it may cause interference with radio and television reception. 
This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in Part 15 of FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. 
You can determine whether your computer system is causing interference by turning it off. If the interference stops, it was probably caused by the computer or one of the peripheral devices. 
If your computer system does cause interference to radio or television reception, try to correct the interference by using one or more of the following measures:ÂTurn the television or radio antenna until the interference stops. ÂMove the computer to one side or the other of the television or radio. ÂMove the computer farther away from the television or radio. ÂPlug the computer in to an outlet that is on a different circuit from the television or radio. (That is, make certain the computer and the television or radio are on circuits controlled by different circuit breakers or fuses.) 
If necessary, consult an Apple-authorized service provider or Apple. See the service and support information that came with your Apple product. Or, consult an experienced radio/television technician for additional suggestions. 
Important:  Changes or modifications to this product not authorized by Apple Inc., could void the EMC compliance and negate your authority to operate the product.
This product has demonstrated EMC compliance under conditions that included the use of compliant peripheral devices and shielded cables (including Ethernet network cables) between system components. It is important that you use compliant peripheral devices and shielded cables between system components to reduce the possibility of causing interference to radios, television sets, and other electronic devices.
