Important Regulatory Information
Cirronet Product FCC ID: HSW-934 / IC 4492A-934
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 and IC MPE Requirements
Information to user/installer regarding FCC s Maximum Permissible Exposure (MPE)
limits.
Notice to users/installers using the following fixed antennas:
2 dBi Cirronet Omni092
-5 dBi ThinkWireless TWP900A
"Remote Operation"
The field strength radiated by both of these antennas, when connected to a transmitting WIT934, does not
exceed FCC-mandated RF exposure limits for Portable operation (<2.5 cm from body of user) for the
General Population.
Note that the WIT934 must be configured as a "Remote" with a maximum transmitted duty cycle of 7.4%
if it is to be used as a Portable device with either of these antennas.
"Access Point Operation"
The 2 dBi Cirronet Omni092 may also be connected to a WIT934 configured in "Access Point" operating
mode with a higher transmitted duty cycle. In this mode, the radio is considered a Mobile device and the
antenna must be placed at least 20 cm away from any personnel. 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.
9 dBi L-Comm Yagi
The field strength radiated by this antenna, when connected to a transmitting WIT934 does not exceed
FCC-mandated RF exposure limits for Mobile operation. This antenna must be placed at least 20 cm
away from any personnel. 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.
The antennas used with the WIT934 transceiver must not be co-located or operating in
conjunction with any other antenna or transmitter.

Additional Regulatory Statements
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 equivalent
isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
This radio transmitter, IC: 4492A-934 has been approved by Industry Canada to operate with the antenna
types listed below with the maximum permissible gain and required antenna impedance for each antenna
type indicated. Antenna types not included in this list, having a gain greater than the maximum gain
indicated for that type, are strictly prohibited for use with this device.
RFM/Cirronet, OMNI092, Omnidirectional Antenna, 2 dBi, 50 ohms
L-Comm, HG909YE Yagi Antenna, 9 dBi, 50 ohms
ThinkWireless Patch Antenna, -5 dBi, 50 ohms
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 radioelectriques depassant les limites applicables
aux appareils numeriques de Classe B prescrites dans le reglement sur le brouillage radioelectrique
edicte par Industrie Canada.
The FCC ID label must be visible through a window, or it must be visible on an access panel, door or
cover that is easily removed. If neither of the above is possible, a second label must be placed on the
outside of the device that contains the following text: "Contains FCC ID: HSW-934."
