Troubleshooting Guide for Aiwa BST-650 Portable Bluetooth Speaker

Encounter common issues with your Aiwa BST-650 Portable Bluetooth Speaker? Start by ensuring it's charged via USB Type-C (4 hours for full charge).

Bluetooth not connecting? Reset by pressing the reset key, then search for "AIWA BST-650" within 10m range.

For TWS pairing issues, power on both speakers; one enters TWS mode via short-press (hear "True Wireless Stereo Paired successfully"), then connect your device. Battery drains fast? Lower volume, as playtime varies 4-13 hours. Lighting not working? It's tied to playback—start music. Water exposure problems? IPX6 handles jets, but dry thoroughly post-use. No error codes listed, but distortion (THD<10%) signals overdrive—reduce volume. Prevent issues by avoiding full discharge, cleaning ports, and firmware updates via Aiwa support.
