FCC Compliance Statement
- FCC ID: H8N-STI625X
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.
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.
2） This device must accept any interference received, including
interference that may cause undesired operation.
Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Note: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.
This device and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter
“To comply with FCC RF exposure compliance requirements, this grant is
applicable to only Mobile Configurations. The antennas used for this
transmitter must be installed to provide a separation
Distance of at least 20 cm from all persons and must not be co-located or
operating in conjunction with any other antenna or transmitter.”
Notice to OEM integrator
Must use the device only in host devices that meet the FCC/ISED RF exposure
category of mobile, which means the device is installed and used at distances
of at least 20cm from persons. The end user manual shall include FCC Part 15
/ISED RSS GEN compliance statements related to the transmitter as show in this
manual.
Host manufacturer is responsible for compliance of the host system with module
installed with all other applicable requirements for the system such as Part
15 B, ICES 003. Host manufacturer is strongly recommended to confirm
compliance with FCC/ISED requirements for the transmitter when the module is
installed in the host.
Must have on the host device a label showing Contains FCC ID: H8N-STI625X
