• Store the unit in a fresh, dry and dust-free place, out of the
reach of children and pets.

it is not in use for an extended period of time.
Possible Cause
• The volume is too
low.

is too far or there is
an obstruction in

Solution
• Turn up the volume (on your external
device or speaker).
• In AUX mode, check that the cable is
securely connected and the external
device is working properly.
• When using the microphone, check the
cable, then make sure the microphone
is switched on and its volume is enabled
on the speaker.
• In USB or TF mode, check that there
are some compatible files on the stick
or card and that they are not corrupted.
Try reloading the files onto the media
device or use another USB stick or TF
card.
• In BT/TWS mode, make sure the
external device/speakers are placed
within 10 metres with no obstructions.
Check the Bluetooth function on the
external device is on and pair (BT)/
connect (TWS) the speaker(s) again if
necessary.
