Force 180 Input Voltage Range?

The spec sheet for the Force 180 states the Input Voltage is 10 to 30V (Which is the range I would expect, allowing 12 V or 24V DC systems to function).

I just received my first Force 180. The back of the radio says "Vin: 14-30V". 

Did the range really get narrowed? Did I receive an early unit that just does not match specifications yet?

Thank you,
