Sub GHz FSK/OOK Tranceiver Module DATASHEET
1.1 Antenna Considerations:The list of Approved antennas: Dedicated Antenna , the use of a standard antenna jack or
electrical connector is prohibited, and Antenna Gain less than 1.2dBi.
1.2 Usage Instructions under Limited Modular Approval
When used in USA, will only work on the 902-928 MHz Frequency band. The Host product manufacturer must ensure that
the RF behavior adheres to the certification requirements when the module is installed in the final Host product.
Appendix
This document covers the Regulatory Compliance information and related documents shared with customers.
2.1 United States
The module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C
“Intentional Radiators” limited single-modular approval in accordance with Part 15.212 Modular Transmitter approval. Single
modular transmitter approval is defined as a complete RF transmission sub-assembly, designed to be incorporated into
another device, that must demonstrate compliance with FCC rules and policies independent of any host. A transmitter with a
modular grant can be installed in different end-use products (referred to as a host, host product, or host device) by the
grantee or other equipment manufacturer, then the host product may not require additional testing or equipment authorization
for the transmitter function provided by that specific module or limited module device.
The user must comply with all of the instructions provided by the Grantee, which indicate installation and/or operating
conditions necessary for compliance.
A host product itself is required to comply with all other applicable FCC equipment authorization regulations, requirements,
and equipment functions that are not associated with the transmitter module portion. For example, compliance must be
demonstrated: to regulations for other transmitter components within a host product; to requirements for unintentional
radiators (Part 15 Subpart B), such as digital devices, computer peripherals, radio receivers, etc.; and to additional
authorization requirements for the non-transmitter functions on the transmitter module (i.e., SDoC or Certification) as
appropriate (e.g., Bluetooth and Wi-Fi transmitter modules may also contain digital logic functions).
2.1.1 Labeling and User Information Requirements
The module has been labeled with their own FCC ID number. If the FCC ID is not visible when the module is installed
inside another device, then the outside of the finished product into which the module is installed must display a label
referring to the enclosed module. This exterior label can use wording as follows:
Contains Transceiver Module FCC ID: 2ATKS-1269HC or Contains FCC ID: 2ATKS-1269HC
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.
A user's manual for the finished product should include the following statement:
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 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
