If the Three Digit Code did not work, try this next:
Auto-Search Method
The Auto-Search Method is a way you can scan through all of the codes in the table to find the right code for your component.
STEP 1: Manually or using your old remote, turn on the component you want to program—for example, to program your TV, turn on your TV set.
STEP 2: On the URC-A6, press the Component button that you want to program (in this case the button that says TV) and the SELECT [SEL] button at the same time. Hold down both buttons for 2 seconds until the TV Component button light turns on. This signals that you are in programming mode.
IMPORTANT: You have 30 seconds to perform the next step while you are in programming mode. If you do not press a button within 30 seconds, the component LED light will turn off. The remote will exit the programming mode and you will have to start over.
UP5
ARROW
DOWN6
ARROW
STEP 3: Point the URC-A6 remote control toward the component and press the UP 5arrow (or DOWN 6arrow) button once. Each time the UP or DOWN arrow button is pressed, the code will count up (or down) one code number and send a Power OFF signal. When the correct code is sent out, the component will turn off.
