4.5 Volume Adjustment
You can easily adjust the volume by rotating the Jog Dial. You will
hear a beep when the volume reaches maximum or minimum level.
The volume is set and maintained independently at different levels
for each audio source even when you turn off and on the headset.
For example, once you set the volume for mobile phone handsfree,
it will not change even if you adjust the volume for your Bluetooth
MP3 music. So you can always maintain the preferred optimum volume
level for each audio source.
WARNING
Use of the product at a high volume for a long period of time may damage
your eardrums or hearing ability. Keep the volume at a modest level to
prevent damage.
