23•	If	a	power	cord	or	power	supply	becomes	damaged	in	any	way,	stop	using	it	immediately.	•	Unplug	your	device	during	lightning	storms	or	when	unused	for	long	periods	of	time.•	For	devices	with	an	AC	power	cord	that	connects	to	the	power	supply,	always	connect	the	power	cord	according	to	the	following	instructions:1		the	AC	power	cord	into	the	power	supply	until	it	seats	fully.2		the	other	end	of	the	AC	power	cord	into	the	wall	outlet. Warning: Battery  safetyThis	device	contains	a	built-in	battery,	improper	use	of	which	may	result	in	explosion.	Do	not	heat,	open,	puncture,	mutilate,	or	dispose	of	the	product	in	ire.	Do	not	leave	the	device	in	direct	sunlight	for	an	extended	period	of	time,	which	could	cause	melting	or	battery	damage.	The	battery	in	this	device	is	not	user	replaceable	and	should	only	be	replaced	by	Microsoft	or	a	Microsoft	Authorized	Service	Provider.	See	www.microsoft.com/surface/support 	for	additional	details. Warning: Use near WaterTo	reduce	the	risk	of	ire	or	shock,	do	not	use	this	device	near	water	and	do	not	expose	it	to	rain		or	moisture.	Do	not	attempt	to	dry	device	with	a	hair	dryer	or	a	microwave	oven. Warning: Hearing  safetySet	the	volume	loud	enough	to	hear	clearly	in	quiet	surroundings, 	and	no	louder.Do	not	increase	the	volume	after	you	start	listening.	Your	ears	can	adapt	over	time	so	that	high	volume	sounds	normal,	but	the	high	volume	may	still	damage	your	hearing.•	Do	not	increase	the	volume	to	block	out	outside	noise.	The	combination	of	outside	noise	and	sound	from	your	headphones	can	damage	your	hearing.	Sealed	or	noise-canceling	headphones	can	reduce	outside	noise	so	that	you	don’t	have	to	turn	up	the	volume.If	you	can’t	understand	someone	nearby	speaking	normally,	turn	down	the	volume.	Sound	that	drowns	out	normal	speech	can	damage	your	hearing.	Even	with	sealed	or	noise-canceling	headphones,	you	should	be	able	to	hear	nearby	people	speak.Minimize your Time Listening to Loud  soundThe	more	time	you	spend	exposed	to	loud	sound,	the	more	likely	you	are	to	damage	your	hearing.	The	louder	the	sound,	the	less	time	it	takes	to	damage	hearing.•	Minimize	your	time	listening	to	loud	sound.	At	maximum	volume,	listening	to	music	on	he	device	with	headphones	can	permanently	damage	your	hearing	in	15	minutes.•	Even	lower	volumes	can	damage	hearing	if	you	are	exposed	for	many	hours.•	All	of	the	sound	that	you	are	exposed	to	during	a	day	adds	up.	If	you	are	exposed	to	other	loud	sound,	it	takes	less	time	listening	at	high	volumes	to	cause	hearing	damage.•	To	safely	use	the	device	with	no	time	limit,	keep	the	volume	low	enough	that	you	can		carry	on	a	conversation	with	people	nearby.Be aware of Hearing Loss  symptomsStop	using	this	device	and	have	your	hearing	checked	if	you	experience:•	Any	hearing	loss.•	You	hear	ringing	in	your	ears.•	Your	speech	sounds	mufled.•	Sound	seems	dull	or	lat.It	is	a	good	idea	to	have	your	hearing	checked	regularly	by	an	audiologist.

Warning: ac adapter safetyFailure	to	take	the	following	precautions	can	result	in	serious	injury	or	death	from	electric	shock	or	ire	or	in	damage	to	the	device.	To	select	an	appropriate	power	source	for	your	device:•	Use	only	the	power	supply	unit	and	AC	power	cord	that	came	with	your	device	or	that	you	received	from	an	authorized	Microsoft	retailer.•	Do	not	use	non-standard 	power	sources,	such	as	generators	or	inverters,	even	if	the	voltage	and	frequency	appear	acceptable.	Only	use	AC	power	provided	by	a	standard	wall	outlet.•	Do	not	overload	your	wall	outlet,	extension	cord,	power	strip,	or	other	electrical	receptacle.	Conirm	that	they	are	rated	to	handle	the	total	current	(in	amps	[A])	drawn	by	the	device	(indicated	on	the	power	supply	unit)	and	any	other	devices	that	are	on	the	same	circuit.•	On	devices	where	the	AC	prongs	may	be	folded	for	storage,	before	plugging	the	AC	adapter	into	a	power	outlet,	make	sure	its	prongs	are	fully	extended.•	On	devices	where	the	AC	prongs	are	removable	and	where	the	power	supply	uses	a	universal	adapter,	before	plugging	the	AC	adapter	into	a	power	outlet,	make	sure	the	prong	assembly	is	of	the	proper	coniguration 	for	the	power	outlet	and	fully	seated	into	the	adapter. caution: cable and cord safetyArrange	all	cables	and	cords	so	that	people	and	pets	are	not	likely	to	trip	over	or	accidentally		pull	on	them	as	they	move	around	or	walk	through	the	area.	Do	not	allow	children	to	play	with	cables	and	cords.To avoid damaging the power cords and power supply:•	Protect	the	power	cords	from	being	walked	on.•	Protect	cords	from	being	pinched	or	sharply	bent,	particularly	where	they	connect	to	the	power	outlet,	the	power	supply	unit,	and	the	device.•	Do	not	jerk,	knot,	sharply	bend,	or	otherwise	abuse	the	power	cords.•	Do	not	expose	the	power	cords	to	sources	of	heat.•	Keep	children	and	pets	away	from	the	power	cords.	Do	not	allow	them	to	bite	or	chew	on	them.•	When	disconnecting 	the	power	cords,	pull	on	the	plug—do	not	pull	on	the	cord.
