1. Introduction
Thank you for using the Wi-Fi module product provided by Qingdao Intelligent &Precise Electronics Co., Ltd.
Before use, please read this user manual carefully. Please follow the technical specifications when using the module
in your design and develop activities. Qingdao Intelligent &Precise Electronics Co., Ltd has the right to change the
contents of this manual in accordance with the needs of the technical development.
FCC & IC application:
This device complies with Part 15 of the FCC Rules / Industry Canada licence-exempt RSS standard(s). 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.
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.
The device for operation in the band 5150-5250 MHz is only for indoor use to reduce the potential for harmful
interference to co-channel mobile satellite systems.
Les dispositifs fonctionnant dans la bande de 5 150 à 5 250 MHz sont réservés uniquement pour une utilisation à
l'intérieur afin de réduire les risques de brouillage préjudiciable aux systèmes de satellites mobiles utilisant les
mêmes canaux.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
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 the 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 into 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.
MPE Requirements
2
To satisfy FCC / IC RF exposure requirements, a separation distance of 20 cm or more should be maintained
between the antenna of this device and persons during device operation.
To ensure compliance, operations at closer than this distance is not recommended.
Les antennes installées doivent être situées de facon à ce que la population ne puisse y être exposée à une distance
de moin de 20 cm. Installer les antennes de facon à ce que le personnel ne puisse approcher à 20 cm ou moins de la
position centrale de l’ antenne.
La FCC des éltats-unis stipule que cet appareil doit être en tout temps éloigné d’au moins 20 cm des personnes
pendant son functionnement.
