4 Rest the headphones on the processor so that the headphones’ contact point
meets the processor’s contact pin while making sure that the CHG indicator
lights up.
It takes approx. 16 hours to fully charge the battery (the CHG indicator goes off
when charging is complete).
When placing the headphones
on the processor, be sure to
hold them with both hands so
that the right and left
housings are horizontal. Place
the headphones vertically on
the processor then tilt them
back until a click is heard.
If the CHG indicator is not lit
Check if the right and left headphones are rested on the processor correctly. The
indicator will not light up if the headphones’ contact point does not meet the
processor’s contact pin. In this case, remove the headphones and place them on the
processor again so that the indicator lights up.
To recharge the headphone battery after use
Place the headphones on the processor after use. The CHG indicator lights up, and the
DECODE MODE indicator goes off, and then charging starts.
Since the built-in timer recognizes when charging is complete (approx. 16 hours),
there is no need to remove the headphones from the processor after charging has
completed.
