• The UID is used to distinguish between multiple receivers used simultaneously in a single model. It can be left at the default of 0 for a single receiver. When more than one receiver is to be used in the same model, the UID should be changed. Please note that this UID cannot be read back from the receiver, so it is a good idea to label the receiver.
