<br>The transmitter is a little sealed box with 2xAA, and inputs for 2xRJ13 type connectors from the wind/rain instruments. The instruments themselves have no batteries. The transmitter goes under your eaves. The receiver has the LCD display and goes on your wall inside the house. The transmitter box must have the outside thermometer/barmometer in it as well.<br>
<br>Your supposed to power up the transmitter first, then power up the receiver, and it should sync in 30 secs, but of course it doesnt... <br><div><div></div><div class="h5"><br><br><div class="gmail_quote">On 21 March 2010 17:25, Mike Everest <span dir="ltr"><<a href="mailto:mw@freenet.net.au" target="_blank">mw@freenet.net.au</a>></span> wrote:<br>

</div>That may be so, but I suspect that it is quite probably a two-way link<br>
between the 'transmitter' and 'receiver'. I dare say that the wireless<br>
system is built from off-the-shelf components, and so will be a two-way<br>
link. At the very least, the 'receiver' will be sending ack-responses for<br>
the data received from the outdoor unit.<br>
<br>
In which case, if the receive circuits of the outdoor unit are damaged by a<br>
nearby lightning strike (for example) then it will still affect the<br>
communication between the two devices.<br>
<br>
Cheers!<br>
