Integration instructions for host product manufacturers according to KDB 996369 D03 OEM
Manual v01
2.2 List of applicable FCC rules
The Ra-01H is an LoRa Module with digitally modulated systems using an LoRa/FSK/OOK modulation.
It operates on the 903MHz~927MHz band and, therefore, is within U.S. FCC part 15.247 standard
2.3 Specific operational use conditions
The EUT is a LoRa Module
Operation Frequency: 903MHz~927MHz
Modulation Type: LoRa/FSK/OOK
Number Of Channel: 25CH
Antenna Designation: Spring Antenna
Antenna Gain: 3dBi
Ai-Thinker lora Series Module (Ra-01H) designed and developed by Ai-Thinker .This module is used
for long distance spread spectrum communication.，Its RF chip SX1276（as show as figure 1）
Mainly used LoRaTM remote modem ， for ultra-long-distance spread spectrum communication ，
strong anti-interference ， can minimize current consumption. With the help of the SEMTECH the
patent technology of LoRaTM, SX1276 with -148dBm high sensititive ， long range transmission, high
reliablity. Meantime ， relative traditional modulation technique ， LoRaTM modulation technique has
obvious advantages in anti-blocking and selection, It solves the problem that traditional design
scheme can not consider distance, anti-interference and power consumption simultaneously.
Its application can be automatic meter reading, home building automation, security system, remote
irrigation system.
2.4 Limited module procedures
not applicable; Single Modular Approval Request
2.5 Trace antenna designs
Not applicable;
2.6 RF exposure considerations
To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed and
operated with minimum distance between 20cm the radiator your body: Use only the supplied antenna.
2.7 Antennas
The Ra-01H is an LoRa Module beams signals and communicates with its antenna, which is Spring
Antenna. The Spring Antenna gain is 3dBi. Antenna could not be in no-load state when module is
working. During debugging, it is suggested to add 50 ohms load to the antenna port to avoid damage
or performance degradation of the module under long-time no-load condition.
2.8 Label and compliance information
The final end product must be label in a visible area with the following
Host must Contains FCC ID: 2ATPO-RA-01H. If the size of the end product is larger than 8x10cm,
then the following FCC part 15.19 statement has to also be available on the label: This device
complies with Part 15 of 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.

2.9 Information on test modes and additional testing requirements
Data transfer module demo board can control the EUT work in RF test mode at specified test channel.
2.10 Additional testing, Part 15 Subpart B disclaimer
The module without unintentional-radiator digital circuit, so the module does not required an evaluation
by FCC Part 15 Subpart B. The host should be evaluated by the FCC Subpart B.
