SNR at receiver output (dB):
Note: The dual envelope "soft" limiter
provides exceptionally good handling
of transients using variable attack and
release time constants. Once activated,
the limiter compresses 30+ dB of transmitter input range into 4.5 dB of receiver
output range, thus reducing the measured figure for SNR without limiting by 4.5 dB

FCC Notice
108.0
NOTE: This equipment has been tested and found to comply with the limits for a
111.5
Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications to this equipment not expressly approved by Lectrosonics,
Inc. could void the user's authority to operate it.
