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 development 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.
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.
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
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 to this distance is not
recommended.
Region Selection
Limited by local law regulations, the version for North America does not have
a region selection option.
Label
Host labeling requirement: Contains transmitter module FCC ID: 2AJVQ-
RK8812CU”.
Host labeling requirement: Contains transmitter module IC: 22470-RK8812CU”.
