I have a model th057, 3 in 1 Safety 1st Thermometer. I accidentally threw away instructions and it's now saying clean me and 1 of the two pieces causes an err. Is there anyway I can get a copy of the manual or instructions? I've searched online and you don't have this thermometer on your online store. So, I hope to find some help. This thermometer has been used maybe 3 times, but we love it so far.
