uneven  surfaces  may cause  the product  and cart
combination to overturn .
VENTILATION  — Slots  and openings  in the  cabinet  are
provided  for ventilation  and to ensure  reliable
operation  of the  product  and to protect  it from
overheating,  and these  openings  must not be
blocked  or covered.  The openings  should never be

should 
be  unplugged  from the outlet  when left un-
used for a long period of time. GROUNDING OR POLARIZATION
•
If this  product  is equipped  with a polarized  alternating
current  line plug  (a plug  having  one blade  wider than
the  other),  it will  fit into  the outlet  only one way.  This
is  a safety  feature.  If you  are unable  to insert  the plug
fully  into the outlet,  try reversing  the plug.  If the  plug
should  still fail to fit,  contact  your electrician  to
replace  your obsolete  outlet. Do not  defeat  the
safety purpose of the polarized plug.
• If this  product  is equipped  with a three-wire
grounding  type plug,  a plug  having  a third  (grounding)
pin,  it will  only  fit into  a grounding  type power  outlet.
This  is a safety  feature.  If you  are unable  to insert  the
plug  into the outlet,  contact  your electrician  to
replace  your obsolete  outlet. Do not  defeat  the
safety purpose of the grounding type plug.
POWER-CORD  PROTECTION - Power-supply  cords
should  be routed  so that  they  are not likely  to be
walked  on or pinched  by items  placed  upon or
against  them, paying  particular  attention to cords  at
plugs,  convenience  receptacles, and the point  where
they exit from the product .
OUTDOOR ANTENNA GROUNDING  — If an outside
antenna  or cable  system  is connected  to the  product ,
be  sure  the antenna  or cable  system  is grounded  so
as  to provide  some protection  against voltage surges
and  built-up  static charges.  Article 810 of the  National
Electrical  Code, ANSI/NFPA  70, provides  informatio n
with  regard  to proper  grounding  of the  mast  and
supporting  structure, grounding  of the  lead-in  wire
to  an  antenna  discharge  unit, size of grounding
conductors,  location of antenna-discharge  unit,
connection  t o grounding  electrodes,  and
r equirements  for the  grounding  electrode. See  Figur e
A.
LIGHTNING  — For  added  protection  for this  product
during  a lightning  storm, or when  it is  left  unattended
and  unused  for long  periods  of time,  unplug  it from
the  wall  outlet  and disconnect  the antenna  or cabl e
system.  This will prevent  damage  to the  product
due to lightning and power-line surges.
POWER  LINES — An  outside  antenna  system should
not  be located  in the  vicinity  of overhead  power lines
or other electric light or power circuits, or where it
can  fall into  such  power  lines or circuits.  When
installing  an outside  antenna  system, extreme  care
should  be taken  to keep  from touching  such power
lines  or circuits  as contact  with them  might  be fatal.
O VERLOADING  — Do  not  overload  wall outlets ,
extension  cords, or 
integral  convenience  receptacles
as this can result in a risk of fire or electric shock. OBJECT 
AND LIQUID  ENTRY - N ever  push  objects  of
any  kind  into this product  through  openings  as they
may  touch  dangerous  voltage points or short-out
parts  that could  result  in a fire  or electric  shock.
Never spill liquid of any kind on the product .
SERVICING  — Do  not  attempt  to service  this product
yourself  as opening  or removing  covers may expose
you  to dangerous  voltage or other  hazards.  Refer all
servicing to qualified service personnel .
DAMAGE  REQUIRING  SERVICE  -  Unplug  this product
from the wall outlet and refer servicing to qualifie d
service personnel under the following conditions:
•W hen the power-supply cord or plug is damaged.
• If liquid  has been  spilled,  or objects  have fallen  into
the product .
• If the product has been exposed to rain or water.
• If the  product  does not operate  normally  by following
the  operating  instructions.  Adjust only those  controls

qualified  technician  to restore  the product  to its
normal operation.
• If the  product  has been  dropped  or damaged  in any
way.
•W hen the product  exhibits  a distinct  change  in
performance — this indicates a need for service.

are  required,  be sure  the service  technician  has used
replacement  parts specified  by the  manufacturer  or
have  the same  characteristics  as the  original  part.
Unauthorized  substitutions may result  in fire,  electri c
shock, or other hazards.
