Cirronet Product FCC ID: HSW-910M
IC 4492A-910M
Note: This unit has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at their expense.
FCC s MPE Requirements
Information to user/installer regarding FCC s Maximum Permissible Exposure (MPE) limits.
Notice to users/installers using the 8.5 dBi Yagi antenna with the WIT910.
FCC rules limit the use of this antenna, when connected to the WIT910 module, to point-to-point
applications only. It is the responsibility of the installer to ensure that the system is prohibited
from being used in point-to-multipoint applications, omni-directional applications, and
applications where there are multiple co-located intentional radiators transmitting the same
information. Any other mode of operation using this antenna is forbidden.
Notice to WIT910 users/installers using the following fixed antennas:
Cushcraft 8.5 dBi Yagi
The field strength radiated by this antenna, when connected to a transmitting WIT910, may
exceed FCC mandated RF exposure limits. FCC rules require professional installation of these
antennas in such a way that the general public will not be closer than 23 cm from the radiating
aperture of this antenna. End users of these systems must also be informed that RF exposure
limits may be exceeded if personnel come closer than 23 cm to the aperture of this antenna.
Notice to WIT910 users/installers using the following fixed antennas:
Cushcraft 6 dBi Monopole Cushcraft 3 dBi Omni Ace 2dBi dipole
The field strength radiated by any one of these antennas, when connected to a transmitting
WIT910, may not exceed FCC mandated RF exposure limits. FCC rules require professional
installation of these antennas in such a way that the general public will not be closer than 20 cm
from the radiating aperture of any of these antennas. End users of these systems must also be
informed that RF exposure limits may be exceeded if personnel come closer than 20 cm to the
apertures of any of these antennas.
Changes or modifications not expressly approved by the party responsible may void the users ability to
operate the equipment.
