Troubleshooting
Signal Issues
• Verify the coax cable to the over-the-air antenna is connected to both
the RF IN port on the back of the receiver (hand-tighten only) and
also to the over-the-air antenna.
• Verify your antenna has not been moved out of proper alignment.
This can cause signal loss on some or all channels.
• Reset the receiver by pressing and holding the POWER button
located on the front panel. Verify that the LED is red or bright blue.
• If reset doesn’t work (the LED is dim blue), then place the receiver in
standby (press the POWER button), unplug it from the outlet for 15
seconds, then plug it back in. Press the button to turn it back on.
• If you see image pixelization, verify your signal strength and quality
by pressing the MENU button, highlighting and selecting the Settings
menu, theTechnical Info submenu and then Signals and Network.
• The DVR+ is only capable of receiving digital TV channels and will
not tune to a channel that is still broadcasting analog TV signals.
• Visit antennaweb.org on a computer to find out which channels in
your area are broadcasting digital TV signals.

• Verify the DVR+ receiver is connected to broadband Internet service
(recommended) in order to access an extended guide for as much
as 14 days of programming. You can view current information about
this connection by pressing the MENU button, highlighting and
selecting the Settings menu, and then the Network Setup submenu.
• When extended guide data is available over your network
connection, both the guide screen and also info banner will display
“Powered by Rovi.” You can use the color buttons on the remote
control to navigate within the program guide (see page 7).
• Verify your extended guide data is up to date. Typically, this data
is updated every 24 hours. You can view when the guide was last
updated by pressing the MENU button, highlighting and selecting the
Settings menu, the Technical Info submenu and then STB Health.
• If your DVR+ receiver is not connected to the Internet, then the
DVR+ populates the program guide with data from the broadcast
signals. Each channel decides how to populate this data, so the
amount varies. Your receiver displays as much as possible.
• Verify your DVR+ is connected to the network either by a wired
connection (using an Ethernet cable) or a wireless connection (using
the optional USB WiFi Adapter). Press the MENU button, highlight
and select the Settings menu and then the Network Setup submenu.
• Verify that you can access the Internet from other devices connected
to the same network. If there are problems accessing the Internet,
check your network equipment (for example, the WiFi router
or access point). Verify the connections are correct using the
documentation provided with the equipment.
