1) Select options:

"Add a device (for example if you buy a new DVD player)"

"Television"

"My Television manufacturer is not here."

Select the manufacturer, and enter model.

Once the device is created, you're gone have to characterize it, either by using a similar language or create one and digitize all the commands of the remote of your TV.

2)After you created a device; click on it and select
option: "Change the speed settings for this device".
You can setup "Power ON Delay" and "Inter-key Delay" by entering a multiple of 100's in ms.

3)If you have above 100 channels select option b), Even if by typing '9' worked, the Harmony needs to type '0''0''9'otherwise it if you select 2 digits you won't be able to access the channels above 99. Example:
Channel 112 will be interpreted '1''2'. Harmony will "crop" the first digit! That's what happened to me!
