We recommend that you verify that the channel is still available using an up to date reference (see: www.antennaweb.org) and if needed perform a manual channel search. If necessary, download the latest software upgrade into your box, perform a factory reset and run the Set-up Wizard. After channel scan completion all available channels should now been installed.
NOTE: The DVR+ is setup to be quite sensitive to Poor Quality Signals. The DVR+ will Reject signals that your TV might allow to be processed. If this is the case, you must improve your signal.
Receiving ATSC HD TV signals can sometimes be tricky. Many conditions can influence the ATSC HD TV signal while being broadcast. Anything that is between the TV Transmitting tower and your location can affect your ability to receive that TV signal transmission. (Physical obstructions, flat/reflective surfaces, and other signals. e.g. LTE/Cellular, Microwave signals, etc) You may be able to move your antenna 5 feet from where it is now and you could get different results. Please read on to learn more about the signal that you want to receive.
1. Before checking your signal on a certain channel, make certain that you are not recording anything or it may actually be showing a different channel/signal.
2. Tune your DVR+ to any channel that is important to you and you'd want to check the signal strength and quality.
3. Press the exit button on the remote so you are viewing live TV and no on screen menu's are present.
4. Now press the "Channel Up" button until you reach the next higher "primary channel". (If on 13.1, do not change to the next "sub channel", (13.2). Go to channel 14 or higher.)
5. Now press the "Channel Down" button to return to the channel that you want to view/check the Signal Strength & Quality.
6. Now, using your DVR+ remote; Press, Menu>Select Settings>Technical Info>Signals & Network info>
7. You can now observe the two signal meters. If either are fluctuating, then you could expect some reception issues.
8. The "Network ID" will indicate the Real/RF channel that is being received/transmitted. Not necessarily the same channel number as what is in the guide. (Virtual number)
a. You can now confirm your RF Channel/Transmit Channel number. (Network ID), compared with your Virtual Channel Number. Document that Network ID number in case you need to communicate with us about that channel.
10. The meters will be showing the signal Strength and Quality for whichever TV channel you are presently tuned to/watching.
11. To make this a dependable signal, you should monitor the signal meters for optimum signal strength and especially “Signal Quality”, while you re-orient the antenna direction.
12. Pay special attention to the Signal Quality. If it is fluctuating, then that can be the issue. Keep in mind, if quality is fluctuating, the meter readings are not instantaneous. It may momentarily go down to ~35 on the meter screen, but may actually be dropping to 0. The meter is just not fast enough to register that.
