The Safety 1st digital infrared ear thermometer model #49505 is a pretty good thermometer with an innovative shield storage and application system. In fact, the product has many useful features. Sadly, the Safety 1st company is absolutely craptastic when comes to customer support. Specifically, the company sells devices that pertain to safety and well-being and children, so you would think it the company would have highly accessible user manuals and user guides on its website. Not so.
I found that issue the hard way when my thermometer’s battery was replaced after an extended period with a dead battery. As a result of having a dead battery for so long the settings were erased. Unfortunately, that meant the temperature scale was bizarrely set to Celsius (Centigrade). I don’t know why. So off I go, naturally, to the company website in search of a manual or guide to tell me how to switch back to Fahrenheit degrees instead of Celsius / Centigrade degrees. Not there. No forums, no FAQs, nada. And believe it or not, no help from Google searches either. A lot of people had the same problem but no solutions.
That was several months ago. We had cause to use it again today, and was again frustrated by once again having to convert from Celsius to Fahrenheit [formula: ((212-32)/100)*n)+32, where n = reading in degrees Celsius or Centigrade]. I decided to give Google a shot once again. And thankfully, a kind soul had found the answer and posted it.
Here’s how to change from celsius to fahrenheit on the Safety 1st #49505:
With the thermometer OFF, hold the TRIGGER for several seconds until the screen shows “— c” and let go of the trigger. Then press the trigger ONCE and the display will turn to “— f”. Then press the Power button.
There ya go. You found here, on a lonely place on the Internet, the pertinent information the Safety 1st company couldn’t be bothered to give their customers.
