This is the first winter I've owned a Futaba transmitter. I'm extremely happy with it, but I live in the northeast US and its finally starting to get cold in the mornings when I fly, and during the day when I leave the transmitter in my car. I've had no problems at all on several occasions when the temperature was in the low 20's, but its colder now and I was wondering what the actual operating and storage temperature specs are for the 9CAP Super?

I know that a lot of components are only spec'd to the commercial temperature range (0C - 70C) and I'm concerned that if I operate or store it in violation of its temperature specs then the frequency may go out of tolerance or something could be damaged or just not work correctly (like the LCD screen?). Also, I suppose it could void the warranty. I looked in my manual and through the faqs on the Futaba site but could not find the information anywhere.
Thanks a lot
