I believe the wind sensor is a rotating cuff that has a wire which needs to input into the main reader or the wifi unit.if it's the wifi unit you need to check the receiver is picking up the signal.if it's the main readout then check the connection.if it is wireless, you may find a switch on the transmitter to change channel.this may fix the problem, especially if the receiver is near other wireless or bluetooth equipment.
There is a reset button on each sensor unit and there is a reset on the base display. The NA means that the signal is not being sensed from the remote. If you use the reset button on the base you will lose all the historical data. The problem may be related to strong interference from something else nearby, You can bring the sensor inside to see if the base picks it up. IF it does not it may need to be replaced. I have dealt with Oregon Scientific before and they are very good with their support. http://www.oregonscientificstore.com/WMR86A-Oregon-Scientific-Backyard-Pro-Wireless-Weather-Station.product
Use a volt meter to see if the battery is depleted or not. If you replace the battery and the alarm stops then it was a weak battery, If it keeps on then there something setting it off. You can use the information in the owners manual Oregon Scientific BAR629HGU Manuals to troubleshoot it.
Heavens Kaitlan you don't ask much do you? I think you need to spend a happy hour or two online with each question, unless there's a Professor of Climatology reading this.
