How do you program an Emerson smart jumbo universal remote?

Code search by device: Turn on device you want to control (TV, VCR, DVD) Press and hold the CODE SEARCH button until the red indicator light remains red, then release Press the desired mode button (TV, VCR, DVD) and release Press the POWER button slowly, but repeatedly until device turns off. While doing this, the red indicator blinks then stays lit Once the device turns off, press and release the Enter button to install code. The remote should be synced to the device. Another view: Someone on another board pointed out that with some newer models you do not need to press the CHANNEL UP button repeatedly. Rather, you press it only ONCE, and the device will cycle through all the code possibilities. When the TV turns off, it means that the proper code has been found. Immediately press the Enter button to install that proper code. This method (and no other) worked for me.
