Each transmitter has an individually assigned,
unique ID code. In order to start operation, the
receiver must be linked with the ID code of the
transmitter with which it is being paired. Once the
link is made, the ID code is stored in the receiver
and no further linking is necessary unless the
receiver is to be used with another transmitter.
