If your CM-7004 loses antenna signal for an extended amount of time, you may find it locked up with a blank black screen. No response from the remote.
- To correct this, unplug the power from your CM-7004 for a few seconds.
- Re-establish the antenna connection.
- Plug the power back in and allow the CM-7004 to boot back up.
- It should operate normally now.
If you are using a powered antenna or powered antenna preamp in your system, there is a symptom that is becoming common. Symptom is, 'I can only record while the TV is turned on.' It's becoming quite common for preamps to operate on 5vdc, and the amp/preamp arrives with a USB power cable. You have a choice to connect the USB power cable to the provided USB wall power adaptor, (Like a cell phone charger) or, you can connect the USB power cable to a USB port on your TV. If you have it connected to the TV USB port, the amp will lose power when you turn the TV off.
In the scenario above, if you have programs setup to record, and your TV is powered off, your DVR may get poor or no TV signal. Your recording could be of poor quality or no recording at all.
Please note; The CM-7004 has been designed as a Digital signal to Analog signal converter. Primarily the CM7004 is used to accommodate older Analog TV's that do not have an HD ATSC tuner, or a Digital display that does not have an HD ATSC Tuner installed.
Secondary to that, it will also record TV programs. This is an economy set top box and has limited Recording options
*Enabling basic recording capability requires a USB drive (Flash or Solid State), minimum 16GB and maximum 128GB and has been formatted to FAT32. IMPORTANT: The USB drive must be a new, first-time use device in order to be properly formatted for use with ConverterBox.
