Hearing damage		Permanent	hearing	loss	may	occur	if	earbuds	or	headphones	are	
used	at	high	volume. 	You	can	adapt	over	time	to	a	higher	volume	of	sound	that	may	
sound	normal	but	can	be	damaging	to	your	hearing. 	If	you	experience	ringing	in	your	
ears	or	muffled	speech, 	stop	listening	and	have	your	hearing	checked. 	The	louder	the	
volume, 	the	 less	 time	 is	required	 before	your	hearing	 could	be	affected. 	Hearing	 experts	
suggest	that	to	protect	your	hearing:
	
ÂLimit	the	amount	of	time	you	use	earbuds	or	headphones	at	high	volume.
	
ÂAvoid	turning	up	the	volume	to	block	out	noisy	surroundings. 	
	
ÂTurn	the	volume	down	if	you	can’t	hear	people	speaking	near	you.

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 .
Not this
This 
						

							76Chapter 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.
Not this
This
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	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. 
						

							77
Chapter 5      Last, but Not Least
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	optimize	viewing	in	your	environment. 	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.

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

Radio and Television Interference
This	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:
•	 Turn	the	television	or	radio	antenna	until	the	interference	stops. 	
•	 Move	the	computer	to	one	side	or	the	other	of	the	television	
or	radio. 	
•	 Move	the	computer	farther	away	from	the	television	or	radio. 	
•	 Plug	the	computer	into	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.
