SYMPTOM: The volume cannot be turned up 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 the treadmill or other electric appliances 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. a. If there is no sound coming from the television, make sure that the television audio is not muted. b. If there is no sound coming from the television, make sure that your audio wire is not plugged into the audio jack on the console. •• Blue Screen—-If the treadmill is located in the fringe area of a television 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 external antenna to improve the picture. SYMPTOM: The television needs to be cleaned a. UNPLUG THE POWER CORD. To clean the television, wipe the television 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. SYMPTOM: Television reception is poor a. Make sure that the television settings are set correctly. See HOW TO ADJUST THE TV SETTINGS on page 34. •• 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 television settings are set correctly (see HOW TO ADJUST THE TV SETTINGS on page 34). 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. 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.
