Frequently Asked Questions - LU44BTS DUAL
How do I pair my smartphone with the LU44BTS speaker?
Turn on the speaker and activate Bluetooth on your smartphone. Ensure the speaker is in pairing mode (indicated by a blinking LED). Select 'DUAL LU44BTS' from the list of available devices. Once connected, you will hear a confirmation tone.
How long does the battery last on a full charge?
The battery lasts up to 8 hours at 50% volume. Higher volume and bass-heavy music will reduce battery life. Charging with a 5V/1A adapter takes approximately 3 to 4 hours.
Can I use the speaker while it is charging?
Yes, you can play music while the speaker is charging. However, this may generate extra heat and slightly increase the charging time. It is recommended to avoid continuous use while plugged in for prolonged periods.
Why is the sound distorted at maximum volume?
Distortion at maximum volume is normal for small speakers. To get clean sound, lower the volume to 85-90% and, if using an external device, check that the source volume is set below 80% to avoid clipping.
Does the LU44BTS support hands-free calling?
Yes, the speaker has a built-in microphone. When a call comes in, press the Call button to answer or end the call. You can also reject a call by holding the call button for 2 seconds.
How do I reset the speaker if it becomes unresponsive?
If the speaker freezes, turn it off and on again. For a full reset, press and hold the Power button for 5 seconds until the LED flashes quickly. This will clear the Bluetooth pairing list and restore factory defaults.
Can I connect two LU44BTS speakers together for stereo sound?
No, the LU44BTS does not support TWS (True Wireless Stereo) pairing. Each speaker operates independently. To get stereo sound, place the speaker in a room with good acoustics and use a wired connection if available.
What is the effective Bluetooth range?
The Bluetooth range is up to 10 meters in open space. Walls and metal objects can reduce the range. Keep the paired device within line of sight for best performance.
How do I use the FM radio function?
Press the Mode button to switch to FM mode. Then press and hold the Play/Pause button to auto-scan and store available stations. Use Track+ or Track- to browse stored stations. For better reception, connect the 3.5mm AUX cable as an external antenna.
Is the LU44BTS waterproof?
No, the speaker is not waterproof. It is designed for indoor and outdoor use, but it should not be exposed to rain, splashes, or submersion. Keep it in a dry place and avoid creating condensation near the ports.
