So on Friday I played a show with my band, and my buddy who drove my gear to the gig had left my Kemper Power rack (In a Rackcase) in his car overnight. It's winter where I live and it was snowing so naturally, it got really cold. So he gets there, I set my stuff up, everything as usual, I turn the master up and there's no sound. I fiddled around for about 10 minutes, redoing the whole setup and panicking until slowly the sound started coming in. After that everything was fine. I'm still a bit worried though, is it safe to let your Kemper gets this cold? And have you ever experienced the Kemper having to warm-up for this long?

Haven't come across this as I never leave gear in my car overnight.
The manual shows these figures:
Environmental Requirements
Operating temperature: 10° to 35° C (50° to 95° F)
Non-operating temperature: −20° to 47° C (−4° to 116° F)
Relative humidity: 5% to 95% non-condensing
Maximum altitude: 3000 m (10,000 feet)
It reads oddly as the non operating temp. range includes the operating temp. range.
I'm guessing they mean (no op temp) <-20 and >47
