About two years ago, my daughter gave us a La Crosse Indoor / Outdoor
weather station (Model 8300) with an outdoor sensor/transmitter unit.
It worked perfectly until recently, and we've become addicted to it.

Two days ago, the outdoor readings disappeared. I replaced the
batteries in both the indoor and outdoor units, following the
procedure in the manual, but cannot get any outdoor readings.

If you followed them exactly-- removing the batteries from the inside
one- then replacing the batteries in the outside one before replacing
the inside batteries--- Then try reversing the procedure and making
the receiver hot before the sender.

It matters, and I have several remote thingies- and some need an
active receiver first, others need an active sender first.
