2 Multi-RF Board
The Multi-RF Board is a radio modem module. It allows the data exchange in WPAN radio networks.
The Multi-RF Board contains two radio systems:
• ZigBee radio system in 2.4 GHz ISM band
• 868.3 MHz radio system (automatically deactivated for the USA and Canada)
The Multi-RF Board has its own internal voltage controller. The antennas are integrated and strongly
attached to the printed circuit board. No external antenna can be connected.

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 the 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 made to this equipment not expressly approved by SMA America, Inc. may
void the FCC authorization to operate this equipment.
RF Exposure Statement
Radiofrequency Radiation Exposure Information:
