WARNING
This device is not available for laptop or similar portable system.
7.1 FCC (Certification)
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
FCC WARNING: This equipment may generate or use radio frequency energy. Changes or m
odifications to this equipment may cause harmful interference unless the modifications are
expressly approved in the instruction manual. The user could lose the authority to operate t
his equipment if an unauthorized change or modification is made.
U.S. Regulatory Wireless Notice
This products emits radio frequency energy, but the radiated output power of this device is
far below the FCC radio frequency exposure limits. Nevertheless, the device should be used
in such a manner that the potential for human contact with the antenna during normal oper
ation is minimized.
FCC Radiation Exposure Statement
This equipment compiles with FCC radiation exposure limits set forth an uncontrolled enviro
nment.
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.
Caution : Any changes or modifications to this device not explicitly approved by manufactur
er could void your authority to operate this equipment.
End Product Labeling
The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is
not visible when the module is installed inside another device, then the outside of the
device into which the module is installed must also display a label referring to the enclosed
module. This exterior label can use wording such as the following: “Contains Transmitter
Module FCC ID: BEJPCRCUDT3” or “Contains FCC ID: BEJPCRCUDT3”. Any similar wording
that expresses the same meaning may be used. The Grantee may either provide such a label,
an example of which must be included in the application for equipment authorization, or,
must provide adequate instructions along with the module which explain this requirement.
In the latter case, a copy of these instructions must be included in the application for
equipment authorization.
7.2 IC (Certification)
This device complies with RSS-210 of the Industry Canada Rules.
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
IC Warning
This device complies with Industry Canada license-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 undesire
d operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radi
o 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.
IC Radiation Exposure Statement:
This equipment complies with IC radiation exposure limits set forth for an uncontrolled envi
ronment. This equipment should be installed and operated with minimum distance 20 cm b
etween the radiator & your body.
NOTE: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE C
AUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS C
OULD VOID THE USER'S AUTHORITY TO OPERATE THE EQUIPMENT.
End Product Labeling
The modular transmitter must be labeled with its own IC ID number, and, if the IC ID is not
visible when the module is installed inside another device, then the outside of the device
into which the module is installed must also display a label referring to the enclosed
module. This exterior label can use wording such as the following: “Contains Transmitter
Module IC ID: 2703N-PCRCUDT3” or “Contains IC ID: 2703N-PCRCUDT3”. Any similar
wording that expresses the same meaning may be used. The Grantee may either provide
such a label, an example of which must be included in the application for equipment
authorization, or, must provide adequate instructions along with the module which explain
this requirement. In the latter case, a copy of these instructions must be included in the
application for equipment authorization.
