FCC
RF Exposure and Transmission Power Compliance
The JRD-1171 BLE Module complies with the FCC Part 15.247 RF exposure limits set forth for an uncontrolled environment. The module operates in the 2.4 GHz ISM band using Bluetooth Low Energy (2.402 GHz to 2.48 GHz and supports output power up to +3.8 dBm when used with the integrated PA.
To ensure compliance with FCC RF exposure requirements:
- The module must be installed to provide a minimum separation distance of 20 cm from all persons.
- The module must not be co-located or operating in conjunction with any other antenna or transmitter, except in accordance with FCC multi-transmitter product procedures.
Intended Use Environment
The JRD-1171 BLE Module is intended for use in embedded wireless systems operating under the following environmental conditions:
- Operating Temperature: -40°C to +85°C
- Humidity: 10% to 90% non-condensing
- Input Voltage Range: 2.7V to 5.5V
The module is suitable for integration into industrial, consumer, and commercial electronic products requiring wireless BLE connectivity.
Limitations and Restrictions
- This module is limited to operation in the 2402–2480 MHz frequency band (BLE).
- It must be used with a designated PCB layout and antenna configuration to maintain compliance.
- This module is not approved for life-support or critical safety systems without further regulatory certification.
- This module uses a u.FL connector and must be used with approved antennas types only.
