Set Mem+
During the Autoscan process, ComproDTV automatically detects and enables
channels with a valid signal. By default, every available channel will be
enabled and marked with the green icon. However, you can shorten the
list of enabled channels to reduce channel-browsing time. Customize your list
by enabling or disabling channels from the channel list by clicking on the green
icon.
Disabled channels will not be shown when you use the channel Up and Down
or channel surfing functions.
