3. Basic use
■ Place the headset on the head
Turn the speaker pads towards each other, and place the headset on so
that the pads rest comfortably on your ears.
Place the pad indicated with L on the left ear and the pad with R on the
right ear. Adjust the headband length for the best fit.
Warning: When you use the headset, your ability to hear outside
sounds may be affected. Do not use the headset where it can endanger
your safety.
When you stop using the headset, ensure that active noise cancellation
is deactivated to save battery power.
■ Active noise cancellation
Active noise cancellation reduces ambient noise in noisy environments.
You can also use active noise cancellation for noise reduction, for
example, on an airplane when Bluetooth connectivity is deactivated
and the CA-143U audio cable is not connected to the headset.
To activate active noise cancellation, slide the power key for active
noise cancellation toward the charger connector. The indicator light
for charging and active noise cancellation is displayed green.
To deactivate active noise cancellation, slide the power key away from
the charger connector. The indicator light for charging and active noise
cancellation turns off.
■ Adjust the volume
To adjust the headset volume, press the volume up or down key during
a call or while listening to music. To adjust the volume quickly, press and
hold either key.
You can also adjust the volume on the connected device if it supports
this feature with the headset.
