Portable Speaker volume decreases and stays low

IMPORTANT: If model-specific information is needed to complete these steps, refer to the manual supplied with the product.

The following situations may cause your portable speaker to output low volume even at the highest settings: 

• The volume of a device connected to the AUDIO IN terminal of the speaker is set to low.
  • Turn up the volume of the connected device.

    NOTE: Some models do not have an AUDIO IN terminal. For specification of the TV, refer to the manual.

• The portable speaker battery level is low. The charge indicator on the speaker flashes slowly in orange if the speaker battery level is low.
  • To resolve the issue, turn off the speaker and charge the battery.

    Note: The built-in battery may run low when you use the speaker at a loud volume for a long period of time, even if you connect it to an AC outlet.  As a result, the sound becomes low.
