The FCC requires that the following statements 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.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) This
device may not cause harmful interference, and (2) this device
must accept any interference received, including interference
that may cause undesired operation.

(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)
