Safety Precautions
- 2 -
WARNING : TO PREVENT FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE
THIS APPLIANCE TO RAIN OR MOISTURE.
CAUTION : TO REDUCE THE RISK IF ELECTRIC SHOCK, DO NOT
REMOVE COVER (OR BACK). NO USER SERVICEABLE PARTS
INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
THIS SYMBOL IS INTENDED TO ALERT THE USER TO THE
PRESENCE OF UNINSULTED "DANGEROUS VOLTAGE"
WITHIN THE PRODUCT'S ENCLOSURE THAT MAY BE
SUFFICIENT MAGNITUDE TO CONSTITUTE A RISK OF
ELECTRIC SHOCK TO PERSONS.
THIS SYMBOL IS INTENDED TO ALERT THE USER TO THE
PRESENCE OF IMPORTANT OPERATING AND MAINTENANCE
(SERVICING) INSTRUCTIONS IN THE LITERATURE
ACCOMPANYING THE APPLIANCE.
CAUTION
TO PREVENT ELECTRIC SHOCK, DO NOT USE THIS POLARIZED AC
PLUG WITH AN EXTENSION CORD, RECEPTACLE OR OTHER OUTLET
UNLESS THE BLADES CAN BE FULLY INSERTED TO PREVENT BLADE
EXPOSURE.
LASER SAFETY
THIS UNIT EMPLOYS A LASER. ONLY QUALIFIED SERVICE PERSONNEL
SHOULD REMOVE THE COVER OR ATTEMPT TO SERVICE THIS DEVICE
DUE TO POSSIBLE EYE INJURY.
CAUTION : USE OF ANY CONTROLS, ADJUSTMENTS, OR PROCEDURES
OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS
RADIATION EXPOSURE.
CAUTION : TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF
PLUG TO WIDE SLOT, FULLY INSERT.

Important Safety Instructions
- All the safety and operating instructions should be read before
the appliance is operated.
- The safety and operating instructions should be retained for
future reference.
- All warnings on the appliance and in the operating instructions
should be adhered to.
- All operating and use instructions should be followed.
1. Water and Moisture - The appliance should not be
used near
water - for example, near a bathtub, washbowl, kitchen sink,
laundry tub, in a wet basement, or near a swimming pool,
and the like. 2. Carts and Stands - The appliance
should be used only with a cart or
stand that is recommended by th
manufacturer.
3. An appliance and cart combination
should
be moved with care. Quick
stops, excessive force, and uneven
surfaces may cause the appliance
and
cart combination to overturn.
4. Wall or Ceiling Mounting - The appli-
ance
should be mounted to a wall or
ceiling
only as recommended by the manufacturer.
5. Ventilation - The appliance should be situated so
that its
location or position does not interfere with
its proper
ventilation. For example, the appliance
should not be situated
on a bed, sofa, rug, or
similar surface that may block the
ventilation
openings; or, placed in a built-in installation, such
as a bookcase or cabinet that may impede the flow of air
through the ventilation openings.
6. Heat - The appliance should be situated away from heat
sources such as radiators, heat registers,
stoves, or other
appliances (including amplifiers) that
produce heat.
7. Power Sources - The appliance should be
connected to a
power supply only of the type
described in the operating
instructions or as marked
on the appliance.
8. Grounding or Polarization - The precautions that
should be
taken so that the grounding or
polarization means of an
appliance is not defeated.
9. 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 appliance.
10.Protective Attachment Plug - If the appliance is equipped with
an attachment plug having overload
protection. This is a
safety feature.
See Instruction Manual for replacement or
resetting of
protective device. If replacement of the plug is
required, be sure the
service technician has used a
replacement plug
specified by the manufacturer that has the
same overload protection as the original plug.
11.Cleaning - The appliance should be cleaned only as
recommended by the manufacturer.
12.Power Lines - An outdoor antenna should be located
away
from power lines.
CAUTION
RISK OF ELECTRIC SHOCKS
DO NOT OPEN
PORTABLE CART
Figure 2

Safety Precautions
- 3 -
13.Outdoor Antenna Grounding - If an outside antenna is
connected to the receiver be sure the antenna
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 information with
regard to
proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna-dis
charge unit, size of grounding conductors,location of antenna-
discharge unit, connection to grounding electrodes and
requirements for the grounding electrode. See Figure 1.
14.Non-use Periods - The power cord of the appliance should be
unplugged from the outlet when left
unused for a long period
of time.
15.Object and Liquid Entry - Care should be taken so
that objects
do not fall and liquids are not spilled into the enclosure through
openings.
16.Damage Requiring Service - The appliance should
be
serviced by qualified service personnel when:
a) The power-supply cord or the plug has been
damaged; or
b) Objects have fallen, or liquid has been spilled
into the
appliance; or
c) The appliance has been exposed to rain; or
d) The appliance does not appear to operate
normally or
exhibits a marked change in
performance; or
e) The appliance has been dropped, or the
enclosure
damaged.
17.Servicing - The user should not attempt to service the
appliance beyond that described in the operating instructions.
All other servicing
should be referred to qualified service
personnel.
