Sound is distorted
I hear crackling noises, or the sound coming from the device isn't clear.
Bad Bluetooth connection
Bluetooth is a radio technology that is sensitive to objects between the Jabra Speak 510 and the connected device. Ensure the Jabra Speak 510 and the connected device are within range (up to 100 meters or 300 feet) and there are no obstacles blocking the bluetooth connection.
Dirt in the speaker
There might be some dust particles in the speaker, so you will need to clean the front plate of the device. If the sound distortion continues, open the device and take the speaker out to clean the actual speaker more intricately. (See Guide)
Unconnected or frayed wire
Open the device and make sure that all of the wires between the speaker and the motherboard are connected. (See Guide) for accessing motherboard. Also, make sure that there is no fraying of the wires. If the wires are disconnected, simply reconnect them if possible. Otherwise, the wires will need to be replaced.
Lights but no sound
The device is on, but there is no sound coming from the speaker.
Volume is set too low
Increase the volume by turning up by pressing the "+". The volume level is indicated by the white lights around the speaker.
Make sure that the Jabra Speak 510 is connected to another device.
Speaker is disconnected
Open the device and check to make sure all of the wires that run from the speaker to the motherboard are connected and not frayed. (See Guide) for accessing the motherboard.
The magnet on the speaker may need to be replaced, so you will need to open up the device and take out the speaker to check the magnet’s condition. (See Guide) for accessing the motherboard.
