Reset outdoor sensor timex weather station - Radio Shack Extra Low Temperature Outdoor Weather Sensor

Remove all batteries from outdoor sensor and weather station.

Press one of the buttons on the weather station at least 20 times to clear all memory.

Verify that the weather station is blank before proceeding (there may be lines painted on
the screen that will show when power is removed).

Leave both units without power for 15 minutes (very important).

Insert fresh batteries into the clock.

Insert fresh batteries into the outdoor sensor.

Press the TX button on the outdoor sensor to transmit RF signal.

Keep the outdoor sensor 5-10 feet from the forecast station.

When RF connection is established, the temperature will appear on the station. Allow the
outdoor sensor and weather station to sit together for 15 minutes to establish a strong
connection.

Check the battery in the outdoor unit, resync them per the instructions, if that does not work check for interference.

There are a couple of possibilities for the failure to transmit/receive outdoor data. First, resynch the two units. This will depend on the manufacturer. For some brands, you need to take the batteries out of both the indoor and outdoor units for 10 minutes. Then put the batteries into the devices with both side by side (working inside is easier). Wait until the outdoor data is displayed. There are some weather station systems where the outdoor unit isn't weather-proof. You may need to dry the outdoor unit for several days after removing the batteries before resynching it to indoor sensor.

If the data displays properly when the outdoor unit is inside, you may have the outdoor sensor too far away from the indoor unit. (The distance will depend on the number of walls and the composition of the wall studs/siding.) Try keeping the two units closer together.

If the outdoor data isn't displayed when the two units are side by side and the reset procedure doesn't work. One device has an internal malfunction (transmitter or receiver failed). It's probably best to replace the unit. If it is under warranty, contact the manufacturer.

I hope this helps. For specific details on resetting the indoor and outdoor units to synch them, please add a comment with the make/model of your weather station.

(I've seen Davis Weather stations damaged by a close lightning strike. The outdoor unit had to be replaced.)

I have two of these and they lose the signal occasionally. Per the manual: Make sure all batteries are good and then press the TX button on the remote sensor for 3 seconds so it sends a wireless signal to the weather station. It should beep. Then on the weather station hold the CH button for 5 seconds to make it search for the transmitter until the outside temp appears. Just removing batteries and reinstalling them in various orders doesn't work. You must re-establish the wireless connection between the outdoor sensor and weather station.

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.

Double check the batteries to make sure they are installed correctly. If one of the batteries in the outdoor sending unit is in backwards, it will not send the outdoor data. On the indoor unit, there is typically one battery that is used for receiving the signal from the outdoor unit. If all of the batteries are in correctly but that one, you will see the display and the indoor temperature information, but the outdoor information will not be displayed. If there are reset buttons, also try them.
