A. Appendix A
A.1. Requirement of FCC KDB 996369 D03 for module certification:
1.1 List of applicable FCC rules:
The module complies with FCC Part 15.247
1.2 Summarize the specific operational use conditions:
The module has been certified for Fix, Mobile, Portable applications. This transmitter must not be co‐located
or operating in conjunction with any other antenna or transmitter.
1.3 Limited module procedures:
The module has not its own RF shielding, which belong to Limited module Standard requires:
Clear and specific instructions describing the conditions, limitations and procedures for third‐parties to use
and/or integrate the module into a host device (see Comprehensive integration instructions below).
Resolve: Supply example as follows:
Installation Notes:
1) CSM92F30 Module Power supply range is DC 1.8V~3.6V, when you use CSM92F30 Module design
product, the power supply cannot exceed this range.
2) When connect CSM92F30 Module to the host device, the host device must be power off.
3) Make sure the module pins correctly installed.
4) Make sure that the module does not allow users to replace or demolition.
1.4 Trace antenna designs:
Not applicable.
1.5 RF exposure considerations:
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
This modular must be installed and operated with a minimum distance of 20 cm between the radiator and user
body.
Note: the host product manuals must include a statement in order to alert the users of FCC RF exposure
compliance.
1.6 Antennas:
Type Gain
PCB 0.5dBi
The antenna is permanently attached, can’t be replaced.
1.7 Label and compliance 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 to this unit not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
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 andused 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.
The system integrator must place an exterior label on the outside of the final product housing the
2AGM5CSM92F30 Modules. Below is the content that must be included on this label.
The host product Labeling Requirements:
NOTICE: The host product must make sure that FCC labeling requirements are met. This includes clearly
visible exterior label on the outside of the final product housing that
displays the contents shown in below:
Contains FCC ID:2AGM5CSM92F30
1.8 Information on test modes and additional testing requirements:
When testing host product, the host manufacture should follow FCC KDB Publication 996369 D04 Module
Integration Guide for testing the host products. The host manufacturer may operate their product during the
measurements. In setting up the configurations, if the pairing and call box options for testing does not work,
then the host product manufacturer should coordinate with the module manufacturer for access to test mode
software
1.9 Additional testing, Part 15 Subpart B disclaimer:
The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) list 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. The final host product still requires Part 15
Subpart B compliance testing with the modular transmitter installed when contains digital circuity.
1.10 Information on test modes and additional testing requirements:
When testing host product, the host manufacture should follow FCC KDB Publication 996369 D04 Module
Integration Guide for testing the host products. The host manufacturer may operate their product during the
measurements.
