For wired sources, use the appropriate 3.5 mm or 6.35 mm input or connect a microphone or media player to available wired inputs. Tune the FM radio via the built-in tuner if using broadcast sources. Adjust volume and tone controls to achieve clear voice projection or balanced music playback. When finished, power down the unit and stow the cord and accessories securely.
Usage recommendations
For optimal voice clarity, position the speaker so the front grille faces the audience and keep the input gain at moderate levels to avoid distortion. When using battery power, ensure the battery is fully charged before extended outdoor use and keep a backup power source if continuous operation is required. Maintain moderate volume levels in enclosed spaces to prevent feedback and check connections before each use.
