with the instructions, may cause harmful interference to radio com
munications. 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 turn
ing 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 important announcement
Important Note:
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 0cm between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter. Country Code selection feature to be disabled
for products marketed to the US/Canada. This device is intended only for OEM
integrators under the following conditions:
- The antenna must be installed such that 0 cm is maintained between the antenna and users, and
- The transmitter module may not be co-located with any other transmitter or antenna,
- For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G band by supplied firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change. (if modular only test Channel 1-11)
As long as the three conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.
Important Note:
In the event that these conditions cannot be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC
authorization is no longer considered valid and the FCC ID cannot be used on
the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and
obtaining a separate FCC authorization.
