Microphone used in C3 can be set to ‘Mic.
Boost’ and ‘Mic. Normal’ modes.
To toggle between ‘Mic. Boost’ and ‘Mic.
Norma’ modes, short click ‘+’ and ‘-’
buttons together. To press the 2 buttons
easily, press the middle space between ‘+’
and ‘-’ buttons.
In ‘Mic. Boost’ mode, C3 will deliver highly
audible voice even if it is not held close to
the mouth but due to influx of surrounding
noise when used in noisy environment, this
mode is recommended for use in quiet
environment such as in home or office.
For use in noisy environment, set the
microphone setting to ‘Mic. Normal’ mode.
In ‘Mic. Normal’ mode, C3 has to be held
closer to the mouth when talking.
Note : The Mic. Boost mode is the default
setting and therefore, change the setting
depending on the talk environment.
