In mode 3, the set interval must elapse and the tag leave the field, and then the tag
will transmit a blink to indicate that it has left the field. If the tag enters a new field, the
tag transmits a blink when it enters the field. If the re-trigger time out is reached before a
new field is entered a blink is transmitted which indicates the tag is out of the field.
