The ResTek Cable TV System is a digital QAM system

Requirement

  • Your TV must have a QAM tuner, or you will need a converter box (example, though not specifically endorsed by ResTek) that will tune a digital QAM signal. Most televisions manufactured since 2006 have a QAM tuner.
  • If your television does not have a QAM tuner, you can buy a new TV or purchase a digital-to-analog converter box. Again, be sure to check the manufacturer’s specifications of any TV or converter box you purchase to make sure it is QAM compatible, not just ATSC or NTSC, because some TVs and many converter boxes are not.

Setting Up Cable TV in Your Room

  1. Attach the Coaxial Cable to the back of your TV.
  2. Attach the other end of the Coaxial Cable to the wall jack.
  3. Perform a (Digital) Cable Channel Scan
    1. Most TV’s have different menu layouts so the basic steps are as follows:
      1. Open the TV’s main menu
      2. Navigate to the channel or settings menu. The nomenclature can vary
      3. Select the Digital Channel Search option. (if Digital Channel Search is not available select Channel Search
      4. The Channel Search may take a few minutes, once it is finished you should be able to view all of the available channels. The channel list can be found here.

Troubleshooting Problems

“I’m only getting a few channels”

Make sure that your TV is set to Cable instead of Antenna.

  1. On your remote, find and press the “Menu” or “Settings” button.
  2. Look through the list of options and find “Cable Settings”
  3. Be sure that this is set to “Cable” or “CATV”
  4. Some older TV’s have an actual Switch on the back of the TV

“I get all the channels but they are fuzzy”

  1. Ask if you can borrow a friend or neighbor’s cable and try that one with your TV
  2. Try a different TV with your original Cable.
  3. Try a different TV with a friend’s cable.
  4. Ask a friend or neighbor to see if you can try their cable port, and go through the first 3 steps again. If it works, then there might be a problem with your Cable port.
  5. Still having troubles, Call ResTek and they can contact Telecom to fix a port problem.

“I have a bunch of channels that are all static or blank, but the normal channels work”

  1. On your remote, find and press the “Menu” or “Settings” button.
  2. Look through the list of options and find the “Auto Program” option. If you can not find this option, look in your manual for this function.
  3. Enable the “Auto Program” and let it run through all the channels. It will take out most (if not all) of the empty signals.

Info about digital cable tuners

QAM (Required)

  • QAM (quadrature amplitude modulation) is the format by which digital cable channels are encoded and transmitted via cable television providers, including CWRU. A QAM tuner is the cable equivalent of an ATSC tuner which receives over-the-air digital channels broadcast by local television stations. Many new cable-ready digital televisions support both of these standards. Because there is no requirement, though, some very inexpensive manufacturers or models may not include the QAM tuner.Please be advised that less expensive TVs sometimes come with a lower quality QAM tuner that may be unable to tune all of the channels. We have found this to be true of bargain brands such as Dynex, Insignia, as well as some low-cost models from Visio. If that is the case a digital conversion box can be purchased.

NTSC Tuner (Not compatible)

  • NTSC, named for the National Television System Committee, is the analog television system used in the United States from 1941 to 2009. After nearly 70 years of use, the FCC ordered the discontinuation of most over-the-air NTSC transmissions in the United States in 2009. Analog channels are still available on many cable systems to provide basic programming without the use of a cable conversion box. Some manufacturers no longer include this type of tuner in televisions built after 2009.

ATSCTuner (Not compatible)

  • An ATSC (Advanced Television Systems Committee) tuner, often called an ATSC receiver or HDTV tuner is a type of television tuner that allows reception of digital television (DTV) television channels transmitted by television stations in North America. The FCC required all television manufacturers to include an ATSC tuner in all products since 2007, and required television broadcasters to switch in 2009. This type of tuner is currently included in all new televisions, including the inexpensive “digital conversion boxes” that were widely available leading up to the 2009 switchover.
