10 CONFIGURATION SETTING
10.2.2 Audio Equalizer (Default: Off)
Increase or decrease the decibel level of different frequency ranges of
audio.
• Balance will adjust all of the frequency ranges to be the same volume
level (0 dB).
• Bass Boost will increase the bass range of audio (20 Hz - 250 Hz).
• Mid Boost will increase the mid range of audio (250 Hz - 4 kHz).
• Treble Boost will increase the high range of audio (4 kHz - 20 kHz).
10.2.3 VOX Phone (Default: Enable)
If this feature is enabled, you can answer incoming calls by voice. When
you hear a ringtone for an incoming call, you can answer the phone
by saying a word such as "Hello" loudly or by blowing air into the
microphone. VOX Phone is temporarily disabled if you are connected
to intercom. If this feature is disabled, you have to tap the TAP Button
to answer an incoming call.
10.2.4 VOX Intercom (Default: Disable)
If this feature is enabled, you can initiate an intercom conversation
with the last connected intercom friend by voice. When you want
to start intercom, say a word such as "Hello" loudly or blow air into
the microphone. If you start an intercom conversation by voice, the
intercom terminates automatically when you and your intercom friend
remain silent for 20 seconds. However, if you manually start an intercom
conversation by tapping the TAP Button, you have to terminate the
intercom conversation manually. However, if you start the intercom by
voice and end it manually by tapping the TAP Button, you will not be
able to start intercom by voice temporarily. In this case, you have to
tap the TAP Button to restart the intercom. This is to prevent repeated
unintentional intercom connections by strong wind noise. After
rebooting the headset, you can start intercom by voice again.
