ESD CAUTION
The CDW-B18189F-02 is ESD (electrostatic discharge) sensitive device and may be damaged with ESD or spike voltage. Although CDW-B18189F-02 is with built-in ESD protection circuitry, please handle with care to avoid the permanent malfunction or the performance degradation.
FCC Statement
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. Any Changes or
modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.

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

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.
The CAM WIFI is designed to comply with the FCC statement. FCC ID is WUI-
BT532767. The host system using CAM WIFI Module should have label indicated it
contain modular’s FCC ID WUI-BT532767 . This radio module must not installed
to colocate and operating simultaneously with other radios in host system
additional testing and equipment authorization may be required to operating
simultaneously with other radio.
The CAM WIFI is deaigned for a compact PCB design.It should be installed and
operated with Dash Cam or other minimum distance of 20 centimeters between the
radiator and your body.” To comply with FCC regulations limiting both maximum
RF output power and human exposure to RF radiation, the maximum antenna gain
including cable loss in a mobile-only exposure condition must not exceed 0dBi
in the 2.4G band. The CAM WIFI and its antenna must not be co-located or
operating in conjunction with any other transmitter or antenna within a host
device. The OEM can use metal antennas or FPC antennas, and the antenna gain
is less than 0dBi for this module.
If difference antenna types or host are used, C2PC should be applied. Notice
to OEM integrator The end user manual shall include all required regulatory
information/warning as show in this manual. The OEM integrator is responsible
for testing their end-product for any additional compliance requirements
required with this module installed. The device must be professionally
installed The intended use is generally not for the general public.lt is
generally for industry/commercial use. The connector is within the transmitter
enclosure and can only be accessed by disassembly of the transmitter that is
not nomally required, the user has no access to the connector. Installation
must be controlled. Installation requires special training This device
complies with Part 15, Subpart C, Section 15.247 of the FCC Rules.
RF warning for Mobile device:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20cm between the radiator & your body.
