What is the operating temperature for this?
I have already bought 3 different mp3 doorbells and none of the push buttons work under approx. -10 Celcius (14 Fahrenheit). I need a push button that 100% reliably transmits at -20 or -25 Celcius (-4 or -13) Fahrenheit. How is it with this one?
Thank you for your question on the model PB75SN wireless door chime push button. Our wireless push buttons do not actually have a temperature rating, but they should have no problem working down to at least zero Fahrenheit. The problem you are probably running into is the strength of the battery at those low temperatures. Please contact our Technical Service Department at 888-336-6151 if you have further questions.
