How to use

Charge the speaker using the supplied USB‑to‑microUSB cable until fully charged. To play via Bluetooth, enable Bluetooth on your smartphone, select the device named STAGE 300 (or the corresponding Rebeltec device name) and start playback from your music app. For USB or microSD playback, insert an MP3‑formatted flash drive or card into the appropriate slot; files will play automatically. To use FM radio, switch the unit to FM mode and tune to the desired station. Connect an external audio source with the included 3.5 mm AUX cable for wired playback. Plug a microphone into the 6.3 mm mic input to use the karaoke function and adjust volume using the built‑in controls.

Usage recommendations

Use the speaker on a flat, stable surface for best sound dispersion. Avoid exposing the unit to rain or excessive moisture; charge with the supplied cable and disconnect when fully charged to maximise battery life. For clearer vocals during karaoke, use a dynamic microphone with a 6.3 mm plug and set microphone volume to a moderate level to avoid distortion.
