Important Regulatory Information
Cirronet Product FCC ID: HSW-934 / IC 4492A-934
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
.5dBi WPANT10022-C2C
Portable Device-Remote Operation
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment is in direct contact with the body of the user under normal operating
conditions. This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
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 any of these antennas.
Mobile Devices-Access Point Operation
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator and your body. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
When configured for mobile operation as an Access Point, a higher transmitted duty cycle of 20.6% is
allowed.

Mobile Devices-Access Point Operation
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator and your body. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
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 comm
ercial 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.

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.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio
exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne
doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage
radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.
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.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut
fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour
l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à
l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la
puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à
l'établissement d'une communication satisfaisante.
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.
Le présent émetteur radio (identifier le dispositif par son numéro de certification ou son numéro
de modèle s'il fait partie du matériel de catégorie I) a été approuvé par Industrie Canada pour
fonctionner avec les types d'antenne énumérés ci-dessous et ayant un gain admissible maximal
et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette
liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour
l'exploitation de l'émetteur.
