How to use
Charge the receiver using the included mini-USB cable before first use.

To turn it off, press and hold the ON/OFF button for 4–5 seconds until the LED changes. Connect the receiver to your speaker or car AUX input using the 3.5 mm male-to-male audio cable; ensure the plug is fully inserted if there is no sound. To pair a new device, press and hold the ON/OFF button for about 7 seconds until the LED flashes red and blue and a voice prompt announces readiness, then enable Bluetooth on your phone, search for devices and select "BT310REV" or "DL-LINK". After successful pairing the LED will flash blue and a voice prompt will confirm the connection. Use your phone to play audio and accept calls through the receiver’s built-in microphone when connected.
Recommendations
For best results, fully charge the RF-BT-X5 before use, keep the receiver within 10 m of the source device and avoid obstacles between devices. If pairing fails, remove previous pairing records on your phone, restart Bluetooth and repeat the pairing steps. Use the supplied 3.5 mm cable for a reliable wired connection to speakers or car AUX inputs.
