SPECIFICATIONS AND FEATURES

The FCC requires that the following statement be included in this manual:

This device complies with FCC radiation exposure limits as set forth for an uncontrolled environment. This device

should be installed and operated so that its antenna(s) are not co-located or operating in conjunction with any

other antenna or transmitter.

(Note: The dual envelope “soft” limiter provides
exceptionally good handling of transients using
variable attack and release time constants. The
gradual onset of limiting in the design begins below
full modulation, which reduces the measured figure
for

SNR without limiting by 4.5 dB)
