Note: The radio's performance may be affected at the temperature extremes. This is considered normal. The radio is
designed to automatically fallback in class and reduces transmitter power to avoid damage to the radio. There is no single
cause for this function. Rather, it is the result of an interaction of several factors, such as the ambient temperature, the
operating mode and the transmit power.
