3. Basic operation
3.1 Charging the case and earphones
Note:
• The case and earphones have internal,
non-removable, rechargeable batteries. Do
not attempt to remove the battery as you
may damage the device.
• Although the case and earphones can be
charged at the same time, it is recommended
to fully charge the case battery before
charging the earphones for the first time.
1. To charge the case, plug the USB cable into
a power source and the micro-USB in the
case’s port. The case starts charging
automatically.
2. Charging the case battery to its full capacity
may take up to 3 hours.
3. When the battery is fully charged, LED
indicator light will become solid green.
4. Proceed to unplug the case from the power
source and place the earphones on the
sockets of the charging case.
5. Turn on the switch of the case to start
charging the built-in batteries of each
earphone.
6. While the earphones are being charged, the
red indicator on each side lights up. When
fully charged, the LED will change to solid
blue. This process will normally take about
an hour.
7. The fully charged buds have power for up to
3.5 hours of talking time or up to 80 hours
of standby time. However, these times may
vary depending on the mobile device used,
on the usage profile, and on the calling/
listening habits of each individual user.
8. “Low battery, please charge” will be heard
to let you know that their voltage is below
the acceptable level to continue operating
properly.
3.2 Turning your earphones on or off
1. To turn your earphones on, press and hold
the
Multifunction
button on each one for
about 4 seconds. The “Power on” prompt
will be heard, making the LED glow red for
one second.
2. As both earphones synchronize, the
“Connected” prompt will be heard first,
followed by “Pairing left channel and right
channel” in order to initially identify each
side. In this case, the LED indication in the
right channel changes to blinking blue, while
the left channel LED will blink alternatively
blue and red to indicate that is ready to pair
with mobile devices.
