Rest the headphones on the
transmitter so that the
headphones’ contact point
meets the transmitter’s contact
pin while making sure that the
charging indicator lights up.
The charging is completed in about
16 hours and the charging indicator
goes off.
When the indicator is not lit
Check if the right and left headphones
are rested on the transmitter correctly.
The indicator may not be lit if the
headphones’ contact point does not
meet the transmitter’s contact pin. Take
off the headphones and place them on
the transmitter again so that the
indicator lights up.
To recharge the headphone
battery after use
Place the headphones on the transmitter
after you use the headphones. Since the
built-in timer recognizes when
charging is complete, there is no need to
take off the headphones from the
transmitter after the completion of
charging.
