Why did my DVR+(CM-7500) not find any channels during installation.

If there is no signal detected, please check your antenna, cable and connections from the antenna to your DVR+ (CM7500).

Connect the antenna to another device/TV Tuner to confirm that there is indeed signal available on that cable.

Note: We recommend that you contact your installer if there is no signal on the antenna output.

Please see the diagrams link attached below to help you understand how to connect your antenna system.
