I'm sure I saw that same message on mine, it started life in MX where 40 was the lowest we ever recorded. My anemometer and rain gauge froze up a week ago yesterday, finally got the anemometer going a couple of days ago and the rain gauge finally thawed out today and I've registered .43" so far as it trickles down - ha. I just drove 50 miles to get 2 small bottles of water, the powered water I've been harvesting and melting for flush water is disappearing fast. IF/when the water ever comes back on, the whole place will need a major scrub down starting with me.
