Note: Forcibly exceeding one or more limit values will cause permanent damage to the module.

Application Notes:

Design Description

1. The recommendations in this manual must be followed to ensure that the module operates properly.
2. The power supply of the module must be a stable voltage without AC ripple. If noise is present, appropriate filtering and decoupling must be performed.
3. After the module is installed, no mechanical stress should be applied to the module.
4. Keep the module away from other high-frequency devices that may interfere with operation, such as other transmitters and devices that generate high-frequency signals.
5. Avoid static electricity, electrostatic discharge and high voltage, which may cause damage to the module. Operators must wear anti-static rings and implement electrostatic protection measures to prevent human static electricity from damaging the chip and firmware.
6. Care should be taken to avoid abnormal supply voltage of the chip on the module due to poor welding short circuit or open circuit of the main board power supply circuit, resulting in chip damage.

Transport and storage

1. During the production and transportation of the module, please take protective measures to prevent the precision parts on the module from being damaged (it is recommended to use anti-collision materials to buffer the reflow furnace exit and assembly, testing, and transportation processes to avoid collisions).
2. Do not expose the module to the following conditions: corrosive gases such as Cl2, H2S, NH3, SO2 or NOX, extreme humidity or salty air, long-term exposure to direct sunlight, and temperatures exceeding the specified storage temperature.
3. Do not apply mechanical stress to the module.
4. Avoid dropping or impacting the module.
5. Avoid static electricity, electrostatic discharge, and high voltage, which may cause damage to the module.

ATTENTION
CONSERVE PRECAUTIONFOR HANDLING ELECTROSTATIC SENSITIVE DEVICES

FCC Statement

This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:

1. This de vice may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause undesired operation.

Changes or modifications 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  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 in stalled 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 ca use 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 important announcement

Radiation Exposure Statement
The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.

Important Note:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

End Product Labeling
The final end product must be labeled in a visible area with the following” Contains FCC ID: 2AA72-PTR54L15

Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.

Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01

List of applicable FCC rules
CFR 47 FCC PART 15 SUBPART C has been investigated. It is applicable to the modular transmitter.

Specific operational use conditions
This module is stand-alone modular. If the end product will involve the Multiple simultaneously transmitting condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer for the installation method in end system.

Limited module procedures
Not applicable

Trace antenna designs
Not applicable

RF exposure considerations
The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.

Antennas
This radio transmitter has been approved by Federal Communications Commission to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device.

Label and compliance information
The final end product must be labeled in a visible area with the following “Contains FCC ID:

Information on test modes and additional testing requirements
Host manufacturer which install this modular with limit modular approval should perform the test of radiated emission and spurious emission according to FCC part 15C:15.247 and 15.209 requirement, only if the test result comply with FCC part 15.247 and 15.209 requirement, then the host can be sold legally.

Integration instructions for host product manufacturers according to KDB 996369 D03

OEM Manual v01

Additional testing, Part 15 Subpart B disclaimer
This transmitter module is tested as a subsystem and its certification does not cover the FCC Part 15 Subpart B (unintentional radiator) rule requirement applicable to the final host. The final host will still need to be reassessed for compliance to this portion of rule requirements if applicable.

Note 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 – Important Note
In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, OEM integrator contact Grantees to make permissive changes or the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
As long as all conditions above are met, further transmitter test will not be required. However the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.
