10.  Grounding or Polarization -

 This video product is equipped

with either a three prong plug for 110 VAC use  or a two prong
flat blade 220 volt type plug.  Each type  is to be inserted into
only the type of receptacle for which they specifically designed
.  

Do not

  cut off the round grounding pin in order to be able to

fit into a two prong receptacle as this could cause injury and will
void the warranty.

11.  Power Sources -

 This product should be operated only from

the type of power source indicated on the marking label.  If you
are not sure of the type of power supplied to your home, consult
your appliance dealer or local power company.

12.    Power-cord  Protection  -

  Power-supply  cords  should  be

routed so they are not likely to be walked on or pinched by items
placed upon or against them.  Pay particular attention to cords and
plugs,  convenience  receptacles,  and  the  point  where  they  exit
from the appliance.

13.  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.

14.    Power  Lines  - 

An  outside  antenna  system  should  not  be

located in the vicinity of overhead power lines, other electric light
or  power  circuits,  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 may be fatal.

15.  Overloading -

 Do not overload wall outlets and extension

cords as this can result in risk of fire or electric shock.

16.  Object and Liquid Entry - 

Never 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.

17.  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.

18.  Damage Requiring Service -

 Unplug this product from the

wall  outlet  and  refer  servicing  to  qualified  service  personnel
under the following conditions:
a.  When the power-supply cord or plug is damaged.
b.    If  liquid  has  been  spilled,  or  objects  have  fallen  into  the
product.
c.  If the product has been exposed to rain or water.
d.    If  the  product  does  not  operate  normally  by  following  the
operating instruction.  Adjust only those controls that are covered
by the operating instructions.  An improper adjustment may result
in damage and will often require extensive work by a qualified
technician to restore the product to its normal operation.
e.    If  the  product  has  been  dropped  or  the  cabinet  has  been
damaged.
f.  When the product exhibits a distinct change in performance -
this indicates a need for service.

19.  Replacement Parts - 

When replacement parts are required,

be sure the service technician has used replacement parts specified
by  the  manufacturer  or  have  the  same  characteristics  as  the
original parts.  Unauthorized substitutes may result in fire, electric
shock or other hazards.

20.  Safety Check -

 Upon completion of any service or repairs to

this product, ask the service technician to perform safety checks to
determine that the product is in proper operating conditions.

21.  Outdoor Antenna Grounding -

 Before attempting to install

this product, be sure the antenna or cable system is grounded so as
to provide some protection against voltage surges and built-up
static charges.
a.    Use  No.10  AWG  (5.3mm  )  copper,  No.8  AWG  (8.4mm
(aluminum, No.7 AWG (10mm ) copper-clad steel or bronze wire
or larger, as    ground wire.
b.  Secure antenna lead-in and ground wires to house with stand-
off insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.
c.  Mount antenna discharge unit as close as possible to where lead-
in enters house.
d.  A driven rod may be used as the grounding electrode where
other types of electrode systems do not exist.  Refer to the National
Electrical Code, ANSI/NFPA 70-1984 for information.
e.  Use jumper wire not smaller than No.6 AWG (13.3mm ) copper
or  equivalent,  when  a  separate  antenna  grounding  electrode  is
used.
