Quick stops, excessive force, and uneven
surfaces may cause the product and cart
combination to overturn.
10 Ventilation – Slots and openings in the cabinet are provided

product and to protect it from overheating, and these
openings must not be blocked or covered. The openings
should never be blocked by placing the product on a bed,
sofa, rug, or other similar surface. This product should not
be placed in a built-in installation such as a bookcase or rack
unless proper ventilation is provided or the manufacturer’s

consult your product dealer or local power company. For
products intended to operate from battery power, or other
sources, refer to the operating instructions.
12 Grounding or Polarization – This product may be equipped
with a polarized alternating current line plug (a plug having
one blade wider than the other). This plug will fit into the
power 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.
13 Power-Cord Protection – Power-supply cords should be

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 cable system. This will prevent
damage to the product due to lightning and power-line
surges.

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.

cords, or integral convenience receptacles as this can result
in a risk of fire or electric shock.

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
