Important Regulatory Information

RFM/Cirronet WIT2492 - FCC ID: HSW-2492, IC ID: 4492A-2492

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.

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

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 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.

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.

Labeling and Notices

Labeling:

A clearly visible label is required on the outside of the user’s (OEM) enclosure stating the following:
”Contains FCC ID: HSW-2492”

”Contains IC: 4492A-2492”

Notices:

WARNING: This device operates under Part 15 of the FCC rules. Any modification to this device, not
expressly authorized by RFM, Inc., may void the user’s authority to operate this device.

FCC NOTICE: This device complies with Part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

IC Notice - This device complies with Industry Canada licence-exempt RSS standard(s). Operation is
subject to the following two conditions: (1) this device may not cause interference, and (2) this device
must accept any interference, including interference that may cause undesired operation of the device.

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type
and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its gain should be so chosen that the equival ent
isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

This radio transmitter, IC: 4492A-2492, has been approved by Industry Canada to operate with the
antenna types listed later in this manual with the maximum permissible gain and required antenna
impedance for each antenna type indicated.

Canadian ICES-003 - This digital apparatus does not exceed the Class B limits for radio noise emissions
from digital apparatus as set out in the radio interference regulations of Industry Canada.

Le present appareil numerique n’emet pas de bruits radioelectriqu es depassant les limites applicables
aux appareils numeriques de Classe B prescrites dans le reglement sur le brouillage radioelectrique
edicte par Industrie Canada.

Canadian Department of Communications Industry Canada (IC) Notice

Canadian Department of Communications Industry Canada (IC) Notice
This apparatus complies with Health Canada’s Safety Code 6 / IC RSS 102.

"To prevent radio interference to the licensed service, this device is intended to be
operated indoors and away from windows to provide maximum shielding. Equipment (or
its transmit antenna) that is installed outdoors may be subject to licensing."
