CAUTION:

The manufacturer is not responsible for any interference caused by unauthorized modi

fi

cations and/or use of unauthorized antennas. Such changes 

and/or modi

fi

cations not expressly approved by the party responsible for compliance of this device could void the user's authority to operate the 

equipment.

RF exposure statement / Antenna Use

Further RF exposure reduction can be achieved if the product can be kept as far as possible from the user body or set the device to lower output 

power if such function is available.

Do not touch or move antenna while the unit is transmitting or receiving.

Do not hold any component containing the radio such that the antenna is very close or touching any exposed parts of the body, especially the face or 

eyes, while transmitting.

Do not operate the radio or attempt to transmit data unless the antenna is connected; this behavior may cause damage to the radio.

FCC Compliance Statement: 

This device complies with Part 15 of the FCC Rules, Subpart B, Unintentional Radiators.

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.

This equipment 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 in a residential installation. This equipment generates, 

uses and can radiate radio frequency energy and, if not installed and 

used in accordance with manufacturer

s instructions, may cause 

harmful interference to radio communications. However, there is no 

guarantee that interference will not occur in a particular installation. If 

this equipment does cause harmful interference to radio or television 

reception, which can be determined by turning the equipment off and 

on, the user is encouraged to try to correct the interference by one or 

more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment to an outlet on a circuit different from that to 

which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

Notice for 5GHz

Operations in the 5.15-5.25GHz band are restricted to indoor usage 

only. (For 5GHz only)

Canadian Department of Communications Statement

This digital apparatus does not exceed the Class B limits for radio 

noise emissions from digital apparatus set out in the Radio Interference 

Regulations of the Canadian Department of Communications. This class 

B digital apparatus complies with Canadian ICES-003.

Avis de conformité à la réglementation d'Industrie Canada

Cet appareil numérique de la classe B est conforme à la norme NMB-

003 du Canada.

Canada-Industry Canada (IC) Regulatory statement

This device complies with Canadian RSS-210.

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 undesired operation 

of the device.

Cet appareil se conforme aux normesCanada d'Industrie de RSS 

permis-exempt. L'utilisation est assujetti aux deux conditions suivantes: 

(1) cet appareil ne peut pas causer d'interférences, et (2) cet appareil 

doit accepter des interférences, y compris des interférences qui peuvent 

causer desopérations non désirées de l'appareil.

Caution: 

When using IEEE 802.11a wireless LAN, this product is 

restricted to indoor use due to its operation in the 5.15-to 5.25-GHz 

frequency range. Industry Canada requires this product to be used 

indoors for the frequency range of 5.15 GHz to 5.25 GHz to reduce the 

potential for harmful interference to co-channel mobile satellite systems. 

High power radar is allocated as the primary user of the 5.25-to 5.35-

GHz and 5.65 to 5.85-GHz bands. These radar stations can cause 

interference with and/or damage to this device. The maximum allowed 

antenna gain for use with this device is 6dBi in order tocomply with the 

E.I.R.P limit for the 5.25-to 5.35 and 5.725 to 5.85 GHz frequency range 

in point-to-point operation. To comply with RF exposure requirements 

all antennas should be located at a minimum distance of 20cm, or the 

minimum separation distance allowed by the module approval, from the 

body of all persons.
