Mute..............Setting this bit to “1” mutes the PC_BEEP.
PV3-0............These bits determine the volume level of the PC_BEEP by 3.0dB step. The volume range is from
0dB to -45dB. When all bits are set to “0”, volume is maximum (0dB) and when all bits are set
to “1”, volume is minimum (-45dB).

Mute..............Setting this bit to “1” mutes the Phone.
GN4-0 ...........These bits determine the volume level of the Phone by 1.5dB step. The volume range is from
+12dB to -34.5dB. When all bits are set to “0”, volume is maximum (+12dB) and when all bits
are set to “1”, volume is minimum (-34.5dB).

GN4-0
Mute..............Setting this bit to “1” mutes the Microphone.
20dB .............Setting this bit to “1” increases +20dB for the microphone volume, which is set to GN4-0 bits.
GN4-0 ...........These bits determine the volume level of the microphone by 1.5dB step. The volume range is
from +12dB to -34.5dB. When all bits are set to “0”, volume is maximum (+12dB) and when all
bits are set to “1”, volume is minimum (-34.5dB).

GR4-0
Mute..............Setting this bit to “1” mutes both left and right channels of the each source.
GL4-0 ...........These bits determine the volume level of the left channel by 1.5dB step. The volume range is
from +12dB to -34.5dB. When all bits are set to “0”, volume is maximum (+12dB) and when all
bits are set to “1”, volume is minimum (-34.5dB).
GR4-0 ...........These bits determine the volume level of the right channel by 1.5dB step.
Setting to them is the same as the upper GL4-0 bits.
