Warnings and Precautions
Federal Communications Commission (FCC)
Compliance - 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 environment. 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. Further, proper installation does not guarantee that
interference will not occur in a particular situation. 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 affected receiver.
• Connect equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult an experienced radio/TV technician for help.
Radio Frequency Notice
– The First InterComm™ System generates and uses RF energy. Changes or
modifications to the equipment may cause harmful interference unless the modifications are expressly
approved in the installation or maintenance manuals. The authority to operate the equipment could be
lost, if an unauthorized change or modification is made.
Electromagnetic Interference/Compatibility
Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately
desogmed. shielded, or otherwise configured for electromagnetic compatibility. It may be necessary to
conduct compatibility testing to determine if any electronic equipment used in or around vehicles is
sensitive to external RF energy or if any procedures need be applied to eliminate or mitigate the potential
for interaction between the First InterComm™ System and other equipment or devices.
• Facilities
– To avoid EMI or compatibility conflicts, turn off the First InterComm™ System near any
facility where posted notices instruct you to do so; e.g., hospitals or health care facilities.
• Vehicles
– To avoid possible interaction between First InterComm™ System and vehicle electronic
control modules (e.g., ABS, engine, or transmission controls), the First InterComm system should be
installed only by a professional installer.
• Pacemakers
– Maintain a minimum separation of 12 inches between First InterComm™ System
components (the VCA100 and associated antennas) and any pacemaker to avoid potential
interference with pacemaker function.
RF Exposure Compliance
Pursuant to FCC rules for the Maximum Permissible Exposure (RF) The antenna(s) specified in this
manual MUST be installed so as to provide a separation distance of at least 18 inches (45 cm) from all
persons.
In addition, the unit may not be used to transmit for more than 50% of the time (average duty cycle over a
30 minute period).
