Important Regulatory Information
RFM/Cirronet WIT2492 - FCC ID: HSW-2492, IC ID: 4492A-2492
FCC s MPE Requirements
Information to user/installer regarding FCC s Maximum Permissible Exposure (MPE) limits.
Notice to users/installers using the following fixed antennas, with Cirronet RF products:
Cushcraft 15dBi Yagi,
Mobile Mark 14dBi Corner Reflector,
Mobile Mark 9dBi Corner Reflector
The field strength radiated by any one of these
antennas, when connected to Cirronet RF
products, 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 2 m 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 2 m to the apertures of any of
these antennas.
Notice to users/installers using the following mobile antennas, with Cirronet RF products:
Mobile Mark 9dBi omni-directional,
MaxRad 5dBi whip,
Cirronet Patch antenna,
Ace 2dBi dipole,
Mobile Mark 2dBi Stub
The field strength radiated by any one of these
antennas, when connected to Cirronet RF
products, 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
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.
The WIT2492 may be used in Portable applications only under the following conditions:
1) When operated in Remote mode where the transmitted duty cycle less than or equal to
5.6%, the WIT2492 may use any type-approved antenna with up to 6 dBi of gain. Antenna gains
exceeding 6dBi are strictly prohibited.
2) When operated in Base mode where the transmitted duty cycle less than or equal to
12.85%, the WIT2492 may use any type-approved antenna with up to 2 dBi of gain. Antenna gains
exceeding 2dBi are strictly prohibited.
Note:
This unit 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 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.
