How to use

Place the speaker on a stable surface or use a suitable stand if available. Connect to mains power (230 V, 50 Hz). Turn on the unit and select the desired input source: Bluetooth for wireless streaming from a phone, the SD card slot for preloaded audio, or the UHF microphone inputs for live speech. Adjust the volume and tone controls on the unit to suit the room and audience size. For wireless microphones, switch on each microphone and ensure each UHF receiver channel is matched to the corresponding microphone.

Recommendations

For best speech intelligibility position the speaker at ear height and avoid placing it directly against walls. Use the UHF wireless microphones at moderate distance to reduce risk of dropouts; keep spare batteries and an SD card with preloaded material for reliable operation during events.
