10. CONTROL SETTINGS
Output levels are adjustable with individual volume controls. For music play or announcement, adjust the
corresponding volume control so that the signal indicator lights intermittently. Note that the sound quality is
downgraded when the peak indicator remains lit.
To prevent the accidental change of the settings of input volume controls, remove their knobs after setting
them to the desired position and attach the volume control covers instead.
