To use my old TV Sets to receive the Over-the-Air digital TV programs, I had to purchase a digital converter box. Combined a $40 coupon from the government, the zenith dtt901 was a very great deal. And it was very easy to set up this small box.
And I like these extra features come with this box, like tune volume, closed caption button, etc. Especially the TV Power button which can turn on/off your TV with the same digital converter box.
I did a lot of Google search, but could not find any information except a lot of reviews. On the Zenith (GE) support site, I could not find the download manual either. As usual, I had to resolve this problem by my own again.
Anyhow, I finally figured it out. SO I posted here for the future reference.
1), With the dTT 901 remote controller on your hand, you should stand in front of the TV and point it towards your TV set.
2), Press and hold the “TV Power” button on the DTT 901 remote control.
3), With that “TV Power” button still held done, now press the channel Up or Down button continuously.
4), If your TV turns on or off, then your remote control found the TV Set code. And you are done.
