Setup
- Unpacking: Carefully remove the speaker from its packaging. Retain all packaging materials for future transport or storage.
- Initial Charging: Before first use, fully charge the speaker's internal battery. Connect the provided AC power cable to the speaker's power input and then to a standard electrical outlet. The charging indicator light (if present) will typically change color or turn off when fully charged.
- Placement: Place the speaker on a stable, flat surface. For optimal sound projection, ensure no obstructions are directly in front of the speaker. If using a pole mount, ensure the tripod stand is rated for the speaker's weight (approximately 27 pounds) and has a sufficiently large footprint for stability.
- Power On: Press and hold the Power button (usually located on the control panel) to turn on the speaker.
Operating Instructions
1. Bluetooth Connection
- Enable Bluetooth Mode: Turn on the speaker. Press the "Mode" button on the control panel until "Bluetooth" or "BT" appears on the display (if available), or a voice prompt indicates Bluetooth mode. The speaker will enter pairing mode, indicated by a flashing Bluetooth indicator light.
- Pair with Device: On your mobile device (smartphone, tablet, etc.), go to the Bluetooth settings and enable Bluetooth. Search for available devices. You should see "PBX-61120BT" or a similar name in the list. Select it to pair.
- Confirmation: Once successfully paired, the speaker will usually emit a confirmation sound, and the Bluetooth indicator light will stop flashing and remain solid.
- Playback: Start playing audio from your device. Adjust volume using both your device's volume controls and the speaker's master volume knob.
Note: A faint hissing sound may be audible when Bluetooth is connected but no music is playing. This is normal and typically disappears once audio playback begins.
2. USB/SD Card Playback
- Insert Media: Insert a USB flash drive or SD card (with compatible audio files) into the respective port on the speaker's control panel.
- Select Mode: Press the "Mode" button until "USB" or "SD" is selected. The speaker should automatically begin playing audio files from the inserted media.
- Controls: Use the playback controls (Play/Pause, Next/Previous Track) on the speaker or the remote control to manage your music.
3. FM Radio Operation
- Select FM Mode: Press the "Mode" button until "FM" is selected.
- Auto Scan: Press and hold the Play/Pause button to initiate an automatic scan for available FM radio stations. The speaker will scan and save stations with strong signals.
- Tune Stations: Use the Next/Previous Track buttons to navigate through the saved FM stations.
Note: FM tuning can sometimes be challenging. Ensure the speaker is in an area with good signal reception for best results.
4. Microphone Inputs
- Connect Microphone: Plug a 1/4 inch TRS microphone into one of the two microphone input jacks on the control panel.
- Adjust Volume: Use the dedicated microphone volume knob (if available) to adjust the microphone's output level. Ensure the master volume is also set appropriately.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the speaker. Do not use abrasive cleaners, waxes, or solvents. Avoid getting moisture into any openings.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Recharge the speaker regularly, especially if it will be stored for an extended period. Store in a cool, dry place.
- Storage: When not in use, store the speaker in a dry environment, away from extreme temperatures and direct sunlight.
- Transport: Utilize the integrated handlebar and wheels for moving the speaker to prevent damage.
