4.1 Getting started
Your IO-12 headphones are shipped with adequate battery
charge for initial use so they can be switched on and enjoyed
immediately.
To switch on your IO-12 headphones press the power
button so that the green indicator illuminates. When
switched on and disconnected from a battery charger,
the remaining battery charge level will be displayed by the
battery indicator. The battery indicator will change colour
from green (>50% charge) via orange to red to indicate
decreasing charge. The indicator will flash red when
battery charge is critically low.
Even though your IO-12 headphones will have battery
charge when first switched on, it is recommended that you
connect them to a charger using the USB cable supplied. A
standard USB mobile phone charger or a computer USB
socket that incorporates an appropriate power supply can
be used. When connected to a charger, the headphone
battery indicator will flash amber while charging and
illuminate in solid green when fully charged.
Battery charge level is
reported audibly by a
headphone voice prompt
at switch on and when
critically low.
If your IO-12 headphones
are left switched on with
no audio source playing,
with no mini jack connec-
tion, and with noise-can-
celling disengaged, they
will switch off automati-
cally after 20 minutes.
