The On/Off key goes out after entering the first number but will light up when you've entered a valid code.
With your other hand, enter the five-digit code for your device. With the device to be programmed turned on, press and hold the corresponding device button on the remote. When you know the manufacturer's code for the device you're programming, entering it directly can be much quicker than using the auto code search. The device is now programmed in the universal remote memory. When the device turns on, press the Stop key. If not, press reverse again until it does. Wait at least two seconds after pressing Reverse to see if the device turns on. Press the Reverse key on the remote to cycle through the last batch of 10 codes. Continue this sequence until the device turns off. If it does not, press Play again and wait another five seconds. Wait five seconds and watch for the device to turn off. Press the Play button on the remote to send a batch of 10 codes to the device. Point the remote at the device you're programming. Press and hold the device key you're programming then press and hold the On/Off key until the key's light comes on and stays on then release both keys. Device keys controlling a single device, such as a TV, don't require a number key.
