mark	both	plug	and	outlet	to	ensure	that	all	products	remain	in	the	proper	
orientation	should	it	become	necessary	to	temporarily	disconnect	the	
system	(as	for	example,	during	an	electrical	storm).
Finally,	the	Wisdom	Audio	SW-1	incorporates	a	fuse	block	that	protects	
both	the	live	and	neutral	(ground)	sides	of	the	circuit.	If	your	SW-1	is	
plugged	into	an	AC	outlet	that	you	know	is	live	(plug	a	lamp	into	it	as	a	
test),	and	yet	appears	to	be	off,	check	the	following:
1
Check the AC cord to make sure it is not damaged.
2.
Check	the	AC	mains	switch	to	ensure	that	it	is	On	(the	side	
with	the	straight	line	is	depressed,	not	the	“O”	side).
3.
If	that	does	not	resolve	the	problem,	turn	Off	the	AC	mains	
switch	(“O”)	and	then	disconnect	the	power	cord	from	the	AC	
mains	receptacle.	
4.
Using	a	small	screwdriver,	gently	pry	open	the	fuse	block	cover	
at	the	top	edge	of	the	assembly.	(You	may	be	able	to	do	it	with	
just	your	fingernail.)
5.
Pull	out	the	fuse	block,	and	check	both	fuses.	If	either	is	blown,	
please	contact	your	local	Wisdom	Audio	dealer	(or	Wisdom	
Audio)	for	service.
