Remedy
For the safety of transportation from overseas, laws
and regulations do not allow the internal battery to be
fully charged at the time of shipping. For that reason,
the voltage may fall below the level required for
operation at the time the user opens the package.
Fully charging the battery before use may relieve this
inconvenience. Please refer to "Power / Charging" on
P.3 regarding the method for charging.
Please return the earphone units to the charging case
to charge them. (In case the battery of the charging
case has run out, please charge the charging case
first.) Please refer to "Power / Charging" on P.3
regarding the method for charging.
Please touch and hold the touch control panel until
the power turns ON. Please refer to "Power ON" on
P.4 regarding the method for turning the earphone
units ON.
In some cases, performing a reset operation may fix
the problem. Please refer to "Factory Reset Method"
on P.7 regarding the reset method.
Please touch and hold the touch control panel until
the power turns OFF. Please refer to "Power OFF" on
P.4 regarding the method for turning the earphone
units OFF.
Normally, if the earphone units are returned to an
adequately charged case, the earphone units will
automatically turn OFF. If the earphone units do not
turn OFF, the battery level of the charging case might
be too low. Please try again after charging the
charging case. Please refer to "Power / Charging" on
P.3 regarding the method for charging.
Normally, if the earphone units are returned to an
adequately charged case, the earphone units will
automatically turn OFF. However, if ear tips other than
those included as accessories are used, there are
cases in which they may interfere with the charging
case and cause the earphones could not be turned
OFF. Please check to see whether the earphone units
turn OFF by using the original ear tips.
In case the touch control panel section has become
soiled or wet, the touch control panel may not
function properly, and it may not be possible to
operate the earphone units. Please wipe the touch
control panel section with a soft, dry cloth to remove
stains or moisture.

Remedy
If the earphone unit' s metal contacts are touching the
pins of an adequately charged charging case, the LED
Indicator will light up in Red. If this is not happening,
please remove the earphone unit, clean the metal
contacts and return it to the charging case again.
Normally, if the earphone units are returned to an
adequately charged case, the earphone units will start
being charged. If the charging does not start, the
battery level of the charging case might be too low.
Please try again after charging the charging case.
Please refer to "Power / Charging" on P.3 regarding the
method for charging.
Normally, if the earphone units are returned to an
adequately charged case, the earphone units will start
being charged. However, if ear tips other than those
included as accessories are used, there are cases in
which they may interfere with the charging case and
cause the earphones to become unable to be charged.
Please check to see whether the earphone units
charge by using the original ear tips.
In case you are using the USB port on a PC, etc., there
are cases in which the output is low and it may take
more time to charge than the publicly listed value.
As such, please use a 5V/1A USB adapter when
charging this product.
In some cases, performing a reset operation may fix
the problem. Please refer to "Factory Reset Method" on
P.7.
Please try performing the pairing operation again
after having deleted the pairing information from a
previously paired device.
Bluetooth communicates using the 2.4GHz band.
This band is used by other wireless standards such
as Wi-Fi, etc., so there is a possibility of receiving
interference. Moreover, this 2.4GHz band does not
penetrate liquids. There is an impact of humidity and
rain, and the human body also contains liquid, so
there are individual differences in connectivity.
Furthermore, it depends on the specifications of
smartphones and other devices.
For that reason, switching OFF unused Wi-Fi /
Bluetooth settings on surrounding devices, etc. is a
countermeasure. While outside, there is a possibility
that moving a smartphone from inside a bag to a
breast pocket, etc. or otherwise reducing the distance
between devices may improve the connection status.
