How to charge the
internal battery?
Insert the microUSB connector
of the charging cable into
the microUSB port of the
CoolBox Intrauricular (turn
off the headphones before
charging). Then connect the
USB connector on the opposite
end of the charging cable to
a free USB port on a running
computer or to a USB port on a
USB charger. The indicator LED
will glow red during charging.
Once the charge is completed,
the LED will glow blue.
Note: : It is convenient to charge
the battery before using the
headphones for the rst time.
Although it is probable that
the battery has charge when
removing the headphones from
its box, this load will only be
partial, so from the beginning
they will not offer the autonomy
announced in the rst use if it
does not previously complete
the load. With low battery the
red light flashes twice.
