Using Code Search
Press and hold the Code Search button on the RCA universal remote control. While continuing to hold this button down, press and then release the button on the remote control that corresponds with the device you are trying to program. For example, if you are programming the television using Code Search on your RCA universal remote control, hold down the Code Search button and then press and release the button marked TV.
The light for the device (such as the TV) should illuminate and then turn off. Once the light has flashed on and off, release the Code Search button. Press the On/Off button on the RCA universal remote control. If the television (or other device you are programming) does not turn off, keep pressing the On/Off button. Continue to do so at a rate of one press per second. What this does is searches through all of the codes on the RCA universal remote until it finds the right one for the device you are programming. Be patient, as this may take up to 100 clicks of the On/Off button to be successful.
Once the television (or other device) powers off following a click, press the Enter button on the universal remote control to save this code for the device. Test it out by turning the device back on and trying other buttons such as the volume or changing a channel. If it works, which it should,you are all set. If not, go back through the steps until it finds the right code.
Repeat the same steps for each device you want to program to use with your RCA universal remote control.
