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.

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.

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.
