3. Basic use
■ Place the headset over the head
Turn the speaker pads towards each other, and place the headset over 
your head 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 or CA-182U 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.
