Unit will not read outside temp model#9160uit

SOURCE: outside temp does not read new batterys in both

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.

To get the outside temperature working again, open the outdoor sensor box carefully loosening the one screw with a screwdriver, insert 3 brand new AA batteries, check phone for outside temperature. If not showing on the phone display, try changing the 'channel' setting, just above the batteries. Be careful not to break the tiny switch. Gently use a smaller flathead screwdriver, if needed. There are 3 settings. Mine worked fine on the first setting. If it is showing on the phone set screens, then, carefully screw the lid back on to the sensor box, and re-insert into the sensor wall holder. I keep mine in a plastic bag on a shelf outside, away from sun, so I can get a true reading day or night. It is always a bit warmer in the sunlight than the true outdoor air temperature. Enjoy
