Fine tuning of return loss etc. can be performed using a matching network. However, it is required to check “Class1 change” and “Class2 change” which the authorities define then.
FCC Statement
RF exposure considerations
The following statements must be described on the user manual of the host device of this module;
for FCC
This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment should be installed and operated keeping the radiator at least 20cm or more away from person’s body.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment should be installed and operated keeping the radiator at least 20cm or more away from person’s body.
for ISED
This equipment complies with ISED radiation exposure limits set forth for an uncontrolled environment and meets RSS-102 of the ISED radio frequency (RF) Exposure rules as this equipment has very low levels of RF energy.
This equipment complies with ISED radiation exposure limits set forth for an uncontrolled environment and meets RSS-102 of the ISED radio frequency (RF) Exposure rules. This equipment should be installed and operated keeping the radiator at least 20cm or more away from person’s body.
The equipment may only be mounted on the host under grant conditions. For use in any other way permitted, additional evaluation, measurement and application for change to Class 2 is required.
Antennas
The device is designed to use the antennas listed below. Do not modify the antenna or any other part of the module. Any modifications will invalidate the modular certifications and require new approvals for the host system.
Label and compliance information
The following information must be indicated on the host device of this module.
for FCC
Contains Transmitter Module FCC ID: YSKW123 or Contains FCC ID: YSKW123
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. *If it is difficult to describe this statement on the host device due to the size, please describe in the user’s manual and also either describe on the device packaging or on a removable label attached to the device.
for ISED(IC)
Contains IC: 4763E-W123
The following statements must be described on the user manual of the host device of this module;
FCC CAUTION
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Information on test modes and additional testing requirements
Test modes should take into consideration different operational conditions for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product.
Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC-authorized for the specific rule parts (ie, FCC transmitter rules) listed on the grant, and the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
Rating EMI Considerations
We recommend to use “best practice” RF design engineering testing and evaluation in case non-linear interactions generate additional non-compliant limits due to module placement to host components or properties. The host manufacturer is responsible for ensuring compliance with the applicable FCC rules for the transmitters operating individually and simultaneously. This includes compliance for the summation of all emissions from all outputs occupying the same or overlapping frequency ranges, as defined by the applicable rules.
How to make changes
Only the grantee is permitted to make permissive changes. Please contact us at +81-42-642-2457.
