Press and hold the “code search” button down until it is lit red. Then press one of your tv. vcd, cd buttons to set up for that specific type of device. Next hit the channel up ((for setting up a TV) or use the "Power" or "play" button for VCRs only). Hit that button until your device responds (for example, the TV will change channels). Here is they key, Immediately after it responds, hit the mute button to save that particular setting (be careful not to go so quickly that you pass up your settings). If some portions of the device do not work, you would have to start over and go past the one(s) that did not work correctly and wait for the device to respond again to another code. NOTE: In order to go through all codes, you would have to hit the button 300 times.

good luck!
