You need to connect the coaxial cable from the antenna to the TV's coaxial RF (TV) connection. (Really old antennas may need a signal adapter - 300 Ohm to 75 Ohm.) Then make sure that the current video source (sometimes labeled Input) is set to TV. On the later Proscan PLED1526A, there is an Input button on both the TV and the remote to cycle through the list of video source options. Enter the menu of the TV (on screen display). Now you should be able to find a sub-menu for setting the channel information. Using the newer model above, you may have a Channel option. Use the left/right arrows to reach that. Then press the Enter to enter the sub-menu. Navigate to Signal Type with the up/down arrows and set this to Air for over the air channels. (Use the left/right arrows to select the signal type and press Enter.) I believe the HRC is for certain cable systems. Then try the Auto Channel Search.

Note: if the TV was manufactured before 2007, it may only have a NTSC tuner. In that case, you'll need a set-top OTA converter box (ATSC to NTSC) to get most channels. Only low-power stations are still broadcasting the NTSC signals. Depending on the model, you can connect this to the RF port of the TV or the AV (composite video) or the YPbPr (component video) source with the appropriate cables. Change the TV input as needed. Then scan for channels following the directions for the converter box.

I hope this helps.
