How to change batteries in outdoor sensor for Model 9080u-it

Try removing all batteries, then reinstalling in the outdoor unit and waiting for it to start sending data before reinstalling batteries in the indoor unit. If you don't see data displayed on the indoor unit, the outdoor unit may have failed.

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.

My pp-sirmt1 outdoor remote sensor display is blank and the clock displays "- -" for outdoor. I have changed both the remote and clock potteries even though they read "Good" on a battery tester. Can I purchase a replacement outdoor sensor unit?

First remove the batteries and wait 5 minutes and then try again. If still no success, make sure that you are close enough to the sensor, take the sensor inside to the readout and see if it picks it up. If it does then there may be interference.

Have you changed the batteries on the outside sender unit?

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.
