Zenith SK64-002 remote programming. Begin programming by holding down the power and mute buttons together until the red LED stays lit. Remote codes are entered like this: Use V- for first digit. CH- for second digit. V+ for third digit. When you are done, press the mute button (small button in center) to enter. Example: Older Sony TVs are code 801. Press the V- button 8 times. (The CH- button doesn't need to be pressed since the second digit is zero.) Press the V+ button once. This is how you enter the code for 8-0-1. Press Mute to save. Wow. Now it works!
