Function Button Function Operation Mode RCA/ Coaxial / SPDI/F /AUX Switch Press once to switch between RCA/ Coaxial / SPDI/F /AUX audio mode. The Led will indicate the input/output status. Power Power ON/OFF Press and hold once to switch the power ON/OFF. RX/TX Switch Transmitter Mode Press once to switch between transmitting mode or receiving mode. The Led will indicate the RX/TX status and show the audio decoding mode. Hold RX/TX Switch for 2S, it will disconnect and clear the pairing device for reconnecting，the LED will flash to indicate. Receiver Mode Indicator Status RCA Inputs/outputs the audio signal via RCA. CDO Inputs/outputs the audio signal via Coaxial. SPDI/F Inputs/outputs the audio signal via SPDI/F In/ SPDI/F Out. AUX Inputs/outputs the audio signal via AUX. SBC Using SBC decoding mode. FS Using FastStream decoding mode. LL Using AptX Low Latency (AptX LL) mode. AAC Using AAC decoding mode. APTX Using AptX mode. Note: 1. Operation range can be affected by Wi-Fi routers, Wireless TV adapters, physical obstructions like walls, metal obstacles etc, and also depended on receiving device. 2. To take advantage of the better performance of the APTX Low Latency codec (~40ms), the other side device must support the same codec. If the other side device only supports the normal AptX codec, or the SBC one, those codecs will be used instead. 3. After Bluetooth connected, the LED will indicate the decoding mode automatically. If your headphones or speakers do not support aptX LL, the LL LED will not light. 4. Moukey MBRT1 does not support simultaneous transmit and receive functions. 5. Digital Optical / Coaxial Audio sources for transmitting must be set to PCM or Stereo. Dolby / DTS input is not supported. Setup Instruction Use as a transmitter (TX mode) 1. Connect audio source (TV, DVD etc.) to MBRT1 audio jacks (RCA/ Coaxial / SPDI/F /AUX) with the audio cables (RCA/ Coaxial / SPDI/F /AUX). 2. Connect MBRT1 to a power source (Highly recommended connecting to power adapter) with a USB-C to USB-A cable. 3. Press the Power button to turn on MBRT1. 4. Select the correct audio input mode (RCA/ Coaxial / SPDI/F /AUX) by pressing the Mode button (Very Important). 5. Press RX/TX switch to the "TX" position. 6. Pairing - Pair MBRT1 with your Bluetooth-enabled headsets/speakers. • Set your headsets/speakers to pairing mode refer to its user manual. • Wait until connected (For quick pairing, better keep them within 1 meter when pairing). • MBRT1 Supports pairing with 2 pairs of Bluetooth equipment. After pairing with one successfully, press the “Power” button twice, MBRT1 will pair the other Bluetooth equipment automatically. (For quick pairing, better keep them within 1 meter when pairing).

RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Bluetooth 5.0 Audio Transmitter and Receiver Model Name MBRT1 FCC ID 2AV7N-MBRT 2. EVALUATION METHOD According to 447498 D01 General RF Exposure Guidance v06 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. Where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 3. CALCULATION P t =8.919dBm=7.796mW The value of the Maximum output power P t is referred to the test report of the CFR47 §15.247. The result for RF exposure evaluation SAR=(7.796mW /5mm) .[√2.480GHz)]= 2.45<3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. 4. CONCLUSION The SAR evaluation is not required.
