The NERO-X is equipped with an
accessory, Activity Clip©, which is used
to attach and stabilize the earphones
during sports or other physical activity.
The clip should be fastened to your shirt
collar. For best comfort, we recommend
that the battery cover side faces the
neck with the clip facing away from the
body.
Battery
To get the integrated high-efficiency
battery to perform optimally and give it
maximum service life you must not let it
become completely discharged between
charges. The NERO-X warns when the
battery power becomes 10% by saying
"Battery low". It is now appropriate to
charge the battery.
Do not charge the battery at temperature
lower than -10°C or higher than + 50°C.
The battery is fully charged when the red
led on the remote control turns off (see
section Use of the remote control).
