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 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 digi
tal device, pursuant to part 15 of the FCC rules. These limits are designed to provide r
easonable protection against harmful interference in a residential installation. This equ
ipment 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 co
mmunications. However, there is no guarantee that interference will not occur in a par
ticular installation. If this equipment does cause harmful interference to radio or televi
sion 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 measu
res: 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 recei
ver is connected. Consult the dealer or an experienced radio/TV technician for help.
You are cautioned that changes or modifications not expressly approved by the party r
esponsible for compliance could void your authority to operate the equipment.
FCC RF Radiation Exposure Statement: 1. This Transmitter must not be co
located or operating in conjunction with any other antenna or transmitter. 2.
This equipment complies with FCC RF radiation exposure limits set forth for an unco
ntrolled environment. This equipment should be installed and operated with a minimu
m distance of 20 centimeters between the radiator and your body.
Information to OEM integrator
The OEM integrator has to be aware not to provide information to the end user regard
ing how to install or remove this RF module in the user manual of the end product. Th
e user manual which is provided by OEM integrators for end users must include the fo
llowing information in a prominent location.
1. To comply with FCC RF exposure compliance requirements, the antenna used for t
his
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, except in accordance with FCC multitransmitter product
transmitter product procedures.
2. Only those antennas with same type and lesser gain filed under this FCC ID numbe
r can be used with this device.
3. The regulatory label on the final system must include the statement: “Contains FCC
ID:PPQ-WN4615L “.
4. The final system integrator must ensure there is no instruction provided in the user
manual or customer documentation indicating how to install or remove the transmitter
module except such device has implemented two
ways authentication between module and the host system.
