Solved the outdoor display issue. Loosen the screws on the remote sensor and remove the batteries. On the main unit use the CH channel button to select which channel you want the unit to pick up the remote sensor on. Once that channel is displayed hold the CH button for three seconds...it will begin to flash. Immediately install the batteries back into the remote sensor. It should pick it up right away. http://www.fixya.com/support/t339468-ge_digital_wireless_thermometer
