How do I change the battery in the Lavatools PT12 Javelin Digital Instant Thermometer?
I've been using my Lavatools PT12 Javelin Digital Instant Thermometer for a while now, and the display is showing "ERROR" and the battery icon. I think it's time to change the battery, but I'm not sure how to do it. Can you provide instructions?
