Some units send out the control signal once when you push the button,
then repeatedly send a "key still down" message until you release.  I
consider this to be a misfeature; it means I can't hold down the button
and wave the control around until the beam hits the base unit.  I have
to keep repressing the button while adjusting my aim.
