2. Regulatory notice to host manufacturer according to KDB 996369 D03 OEM Manual v01
List of applicable FCC rules
This module has been granted modular approval as below listed FCC rule parts.
– FCC Rule parts 15C(15.247)
Summarize the specific operational use conditions
The OEM integrator should use equivalent antennas which are the same type and equal or less gain than an antenna listed in this instruction manual.
RF exposure considerations
The module has been certified for integration into products only by OEM integrators under the following condition:
-The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is maintained between the radiator (antenna) and all persons at all times.
-The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with the FCC multi-transmitter product
procedures.
-Mobile use
As long as the three conditions above are met, further transmitter testing will not be required.
OEM integrators should provide the minimum separation distance to end-users in their end-product manuals.

Antennas list
This module is certified with the following integrated antenna.
-Type: PCB Pattern Antenna
-Max. peak Antenna gain

| Frequency| Antenna gain
---|---|---
BT LE| 2402 ~ 2480 MHz| 1.5 dBi
Wi-Fi| 2412 ~ 2462 MHz| 1.5 dBi

Any new antenna type, a higher gain than the listed antenna should be met the requirements of FCC rules 15.203 and 2.1043 as a permissive change procedure.

Label and compliance information
End Product Labeling
The module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC Certification Number are not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. In that case, the final end product must be labeled in a visible area with the following:

• Contains FCC ID: BEJ-LCWB001
• Contains IC: 2703N-LCWB001

Information on test modes and additional testing requirements
OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, the additional transmitter in the host, etc.).
Additional testing, Part 15 Subpart B disclaimer
The final host product also requires Part 15 subpart B compliance testing with the modular transmitter installed to be properly authorized for operation as a Part 15 digital device.

3. ISED Statement
RSS-GEN, Sec. 7.1.3–(license-exempt radio apparatus)
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause undesired operation of the device.
RF Exposure
The antenna (or antennas) must be installed so as to maintain at all times a distance minimum of at least 20 cm between the radiation source (antenna) and any individual.
This device may not be installed or used in conjunction with any other antenna or transmitter.
Caution: Any changes or modifications to this device not explicitly approved by the manufacturer could void your authority to operate this equipment. Attention:
