If within the LOR Unit 03 definition, there are unused channels, you do not have to create a model for that channel or channel range. For example, let’s say within Unit 03, channels 10-14 are not used. In which case, you would create 9 Trees (1 -9), and then another 2 trees (for 15-16). This is different to the setup tab where you must cover the entire range of channels from 1 onwards.
