Sound Becomes Low While In Use - Panasonic SC-NA07 Operating Instructions Manual

Sound becomes low while
in use
The sound may become low in the following
cases. This is not a malfunction.
When the built-in battery is running low and
•
the indicator on top flashes between red and
blue, while the speaker is being powered by
the built-in battery only.
When the built-in battery is running low as a
•
result of using the speaker at a loud volume
for a long time even if the speaker is connected
to an AC outlet via a USB AC adaptor
(commercially available), or connected to a
booted computer.
If the sound becomes low while in use, follow
the procedure below.
1. Turn off the speaker.
2. Charge the built-in battery sufficiently.
Note
•
This speaker is designed to reduce the
maximum volume to about half when the
remaining built-in battery power becomes
less than 20% in order to protect the circuit
due to extreme voltage fluctuation by using
at a loud volume. Even in this case, you can
charge the built-in battery, but the volume
does not return to the normal. To return the
volume to the normal, charge the built-in
battery until the remaining built-in battery
power reaches 20% or more, turn off the
speaker and turn it on again, and then
adjust the volume.
