Getting Started

Please fully charge your product before first use. To charge, connect it to a USB charger or charging port with the included micro-USB cable. When the red LED indicator turns off, your BR-C19 is fully charged and ready for use. Charging takes around 2 hours.

Pairing

Transmitter Mode 

1. Choose the transmitter mode. Connect one end of the included 3.5mm audio cable to the 3.5mm audio jack on the BR-C19, and connect the other end of the cable to your audio output device (TV, computer, CD player, MP3 player, or other) that doesn’t have a wireless function

Notes 

• In transmitter mode, the BR-C19 will automatically exit pairing mode and go into standby (LED indicator flashing blue once every second) after 2 minutes if no device is paired
• In transmitter mode, the pairing list of your BR-C19 includes up to 4 paired device,s and the BR-C19 will automatically reconnect to the last two successfully paired devices
• When you power off, wait for 3 seconds before switchinmodesde. When you turn on the BR-C19 in receiver mode, the transmitter mode pairing list will be cleared

Receiver Mode

Troubleshooting Guide for AUKEY 2-in-1 Wireless Transmitter & Receiver

Common issues with the AUKEY 2-in-1 Wireless Transmitter & Receiver include connectivity problems, audio latency, device not pairing, and intermittent audio dropouts. To resolve these:

• No pairing or connection: Ensure the device is in the correct mode (Transmitter or Receiver) using the slide switch, and that Bluetooth is enabled on your source device. Restart both devices and clear any previous Bluetooth pairings.

• Intermittent audio dropouts: Reduce interference by moving wireless routers or other Bluetooth devices away from the unit and ensuring the battery is charged or the power supply is stable.
• Error codes: The AUKEY transmitter/receiver generally uses LED indicators rather than detailed error codes. Refer to the user manual for LED status interpretations.

Preventive measures include keeping firmware updated (if applicable), charging the internal battery fully before use, and avoiding excessive physical stress on ports. The product typically includes a 24-month warranty backed by AUKEY’s customer support. For assistance, users can contact support via support@aukey.com or visit the official AUKEY website.
