PROBLEM: Television reception is poor
SOLUTION:
a. Make sure that the television settings are set correctly. See HOW TO
ADJUST TELEVISION SETTINGS on page 12.
b. For the digital television to operate properly, good reception is necessary. If
you are using an antenna, make sure that it is properly connected and
adjusted for optimal reception. (See HOW TO CONNECT AN ANTENNA on
page 6.)
c. Check for the problems listed below and follow the applicable instructions.
• Ignition (black spots or horizontal streaks that appear or a picture that flut-
ters or drifts)—Usually this is caused by interference from automobile
ignition systems, neon lamps, electric drifts, or other electric appliances.
Try changing the position of your exercise equipment or other electric appli-
ances to correct the problem.
• Ghosts—Ghosts are caused by the television signal following two paths—
one is the direct path and the other is reflected from tall buildings, hills, or
other objects. Change the direction or position of the antenna to improve
reception.
• Blue Screen—If you exercise equipment is located in the fringe area of a
television station where the signal is weak, the picture may be of poor qual-
ity or a blue screen may appear. If the signal is weak, it may be necessary
to install an external antenna to improve the picture.
• Fading—If blocks of the picture are missing, the picture moves around the
screen, or the picture disappears, the signal may be weak. Change the
direction or position of the antenna to improve reception. Make sure that
the television settings are set correctly (see HOW TO ADJUST TELEVI-
SION SETTINGS on page 12). Do not use a splitter.
Note: If one of these problems appears when the cable from a CATV company
is connected, the problem may be caused by the local company broadcast.
8. Do not store the television in tem-
peratures below -40° F (-40° C) or
above 140° F (60° C). Do not oper-
ate the television in temperatures
below 23° F (-5° C) or above 90° F
(35° C).
9. To protect the exercise equipment
and television during lightning
storms, unplug the power cord
from the wall outlet and disconnect
the cable system. This will prevent
damage due to lightning and power
line surges.
10. If an outside antenna or cable sys-
tem is connected, make sure that
the antenna or cable system is
grounded to provide some protec-
tion against voltage surges and
built-up static charges. Section 810
of the National Electrical Code,
ANSI/NFPA No. 70-1984, provides
information with respect to proper
grounding of the mast and support-
ing 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 require-
ments for the grounding electrode.
11. An outside antenna system should
not be located in the vicinity of
overhead power lines or other elec-
tric 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 cir-
cuits, as contact with them might
be fatal.
12. Upon completion of any service or
repairs to the exercise equipment
or the television, ask the service
technician to perform safety checks
to confirm that the unit is in proper
operating condition.
• Use No. 10 AWG (5.3 mm
2
) cop-
per, No. 8 AWG (8.4 mm
2
)
aluminum, No. 17 AWG (1.0 mm
2
)
copper-clad steel or bronze wire,
or larger as a ground wire.
• Secure an antenna lead-in and
ground wires to the house with
stand-off insulators spaced from
4 to 6 feet (1.22 to 1.83 m) apart.
• Mount an antenna discharge unit
as close as possible to where the
lead-in enters the house.
• Use a jumper wire not smaller
than No. 6 AWG (13. 3 mm
2
) cop-
per, or the equivalent when a
separate antenna-grounding elec-
trode is used. See NEC Section
810-21 (j).
Note to CATV system installer: This
reminder is provided to call the CATV
system installerʼs attention to Article
820-40 of the NEC that provides guide-
lines for proper grounding and, in
particular, specifies that the cable
ground shall be connected to the
grounding system of the building, as
close to the point of cable entry as
practical.
