Limited module procedures
This module is an unrestricted module
Summarize the specific operational use conditions
The module is limited to OEM installation ONLY. The OEM integrator is
responsible for ensuring that the end-user has no manual instruction to remove
or install module.
The module is limited to installation in mobile application; A separate
approval is required for all other operating configuration.
Trace antenna designs
The module is connected with an external antenna through a RF connector. Product specification：41x7x0.6mm(No glue and cable)
RF exposure considerations

FCC regulatory information
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. Warning: changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
End Device Labelling
Please notice that if the FCC identification number is 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. This exterior label can use wording such as the following: “Contains FCC ID: Z4T-WM1302-A and Z4T WM1302-B” any similar wording that expresses the same meaning may be used
RF Exposure Compliance
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Installation Notice
The module is limited to OEM installation ONLY. The OEM integrator is
responsible for ensuring that the end-user has no manual instruction to remove
or install module.
The module is limited to installation in mobile application; A separate
approval is required for all other operating configurations, including
portable configurations with respect toPart2.1093and difference antenna
configurations.
FCC Part 15B Compliance of End Device
The OEM integrator is responsible for ensuring that the host product which is installed and operating with the module is in compliant with Part 15B unintentional Radiator requirements, please note that For a Class B digital device or peripheral, the instructions furnished the user manual of the end- user product shall include the following or similar statement, placed in a prominent location in the text of the manual:
Note: This equipment has been tested and found to comply with the limits 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 cause harmful interference to radio communications. 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 turning 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.
Information on test modes and additional testing requirements
The module can be connected to the computer through an external USB interface and send ADB commands to open different test modes.
Additional testing, Part 15 Subpart B disclaimer
A statement that the modular transmitter is only FCC authorized for the specific rule parts(i.e., FCC transmitter rules) listed on the grant, and that 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. If the grantee markets their product as being Part15SubpartB compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
