Precautions

This  equipment  has  been  tested  and  found  to  comply  with  the  limits
set  out  in  the  EMC  Directive  using  a  connection  cable  shorter  than  3
metres.

On power sources

The  mains  power  cable  should  be  routed  so  that  it  is  not  likely  to  be
walked  on  or  pinched,  especially  near  the  plug  or  back  panel  recepta-
cle.  The  component  should  not  be  disconnected  from  the AC  power
source as long  as it is connected to  the wall outlet, even  if the compo-
nent  itself  has  been  turned  off.

If  this  component  is  not  going  to  be  used  for  a  long  time,  be  sure  to
disconnect  the  component  from  the  wall  outlet.  To  disconnect  the AC
power  cable,  grasp  the  plug  itself;  never  pull  the  cable.

On placement

The AM-77 may become warm during  normal operation.  Given this, it is
imperative  that  the AM-77  when  installed,  its  location  or  position  DOES
NOT  interfere  with  its  proper  ventilation.

For  example,  it  should  not  be  situated  on  a  bed,  sofa,  rug  or  similar
surface that may  block the top or bottom ventilation  openings; or placed
in  a  built-in  installation,  such  as  a  bookcase  or  cabinet,  that  may  im-
pede  the  flow  of  air  through  its  top  and  bottom  ventilation  openings.

Do  not  place  the  component  in  a  location  near  heat  sources,  or  in  a
place  subject  to  direct  sunlight,  excessive  dust,  or  mechanical  shock.
Do  not  place  the  component  in  an  inclined  position.

It  is  designed  to  be  operated  in  a  horizontal  position  only.  Do  not  place
heavy  objects  on  the  component.

Keep  the  component  away  from  equipment  with  strong  magnets,  such
as  microwave  ovens  or  large  loudspeakers.

To  prevent  fire  or  shock  hazard,  do  not  place  vessels  filled  with  liquids,
such  as  vases,  on  the  component.

Running-In

AMR  estimates  that  the  AM-77  may  take  between  300-500  operating
hours  for  all  of  the  internal  components  to  be  fully-broken  in.  Please
anticipate  the  sonic  performance  of  the AM-77  to  settle  only  after  it  has

been  used  for  this  approximate  length  of  time.
