The outside transmitter for my Lacross weather station, model WS-9080U-IT is not working. I replaced the batteries. How do I get it to transmit?

Sometimes, you have to remove all the batteries in the transmitter and receiver and wait a few minutes before the next step.

Then you replace transmitter batteries first and within 30 seconds, get the batteries installed in the receiver. This allows the receiver to link up with your transmitter. Both units need to be reset this way. You'll see the temperature and any other information the transmitter provides come up in a few minutes. This works with my La Crosse weather station. Using the reset buttons without removing power will not work. My nieghbour has a weather station from another manufacturer and this is also the only way that his will link up.

In some of these weather stations, you have to install the batteries in the transmitter first and then the weather station within a certain time limit. Also, the weather station must be within a specified distance from the transmitter when replacing the batteries.

If you look on the weather station, there should be a make and model number. If you have that, you can visit the website (if there is one) and download an instruction booklet for your model.

Try physically taking your inside unit outside, and replacing the inside unit batteries as close as possible near the outside unit. Once the transmitter has found the signal, it should lock on and continue to work. Good luck.

Try replacing the battery in the outside temp transmitter.

I have a WA-1070T with same problem
brand new would not communicate

look very carefully at the positive end of the battery connections in the outdoor transmitter

One of the two batteries were not making a connection

I had to cut out a small piece of plastic that interfered with battery alignment

As soon as batteries are installed in remote transmitter you will see a red LED flash a few times

After I made this correction everything worked

I've had the same problem since I bought this unit 2+ years ago; when the outside temperature moves into the freezing zone, the sensor stops transmitting. I contacted Lacrosse-- all they could suggest was change the batteries. My solution: throw it in the trash!

I have experienced the same with numerous different, "quote un quote" atomic clocks! Please don't forget that this sender unit, that goes outside, generates a RF Singal to be received by the clock inside. This unit transmits a signal 433 MHz signal approximately every. 3 minutes, and after so many years the sender unit's RF section(electronics) just goes out or no longer function properly or not at all! The transmitter/sender for this model number, according to "3M" is obsolete and can no longer be furnished, DRATTS !!!!!

I have three of these WS-916OU-IT units. After a few years, the outside sensor just fails. You will get dashes and a "TR" low battery signal, even if the batteries are good
just buy another whole weather station (short money) and set both the old and new weather station unit to receive from the single new outdoor sensor.
To do this - just follow the procedure for a single sensor - that is - put the batteries in the new sensor - then within 30 seconds - put the batteries in all the weather stations - they will all pick up the same outdoor sensor.
I now have three units running off of one outdoor sensor.
Seems a bit silly, but it works.
