FCC Notice
NOTE: This equipment has been tested and found to
comply with the limits for a Class B digital device, pur-
suant to Part 15 of the FCC Rules. These limits are de-
signed to provide reasonable protection against harmful
interference in a residential installation. The 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 encour-
aged 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 which the receiver is connected
• Consult the dealer or an experienced radio/TV tech-
nician for help
Changes or modifications to this equipment not ex-
pressly approved by Lectrosonics, Inc. could void the
user’s authority to operate it.
