Digital Tv Reception Is Poor; The Digital Tv Needs To Be Cleaned - NordicTrack Commercial 2950 NTL22113.0 User Manual

SYMPTOM: Digital TV reception is poor
a. Make sure that the digital TV settings are set cor-
rectly. See HOW TO ADJUST THE TV SETTINGS
on page 37.
b. For the digital TV to operate properly, good recep-
tion 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 19.
c. Check for the problems listed below and follow the
applicable instructions:
• Ignition (black spots or horizontal streaks that
appear or a picture that flutters 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 fitness equipment or other
electric appliances to correct the problem.
• Ghosts—Ghosts are caused by the TV signal fol-
lowing 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 your fitness equipment is
located in the fringe area of a TV station where
the signal is weak, the picture may be of poor
quality or a blue screen may appear. If the signal
is weak, it may be necessary to install an exter-
nal 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 the digital TV settings
are set correctly (see HOW TO ADJUST TV
SETTINGS on page 37). 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 cable company
broadcast.
SYMPTOM: The digital TV needs to be cleaned
a. UNPLUG THE POWER CORD. To clean the digital
TV, wipe the digital TV and screen using a soft
cloth with a small amount of soft detergent. Do
not use a polishing cloth, solvent, or any type of
propellant or chemical detergent such as alcohol or
benzene.
