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
NOTE: This equipment has been tested and found to comply with the limits for a 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.
