Wayne: One last thing. Press "in" on the clock adjusting knob with the key "on", hold it in for at least 5 seconds. Watch the outside temp display. You may get a weird display, a 2 digit number followed by a decimal and a "|". Does it do this? Email me with the results, we are cluttering up the whole site with this stuff. email gillybenztech@yahoo.com.....Gilly
