Touching Effective Item on Touchscreen
The buzzer can be silenced most easily by pressing the Buzzer Silent button on the Quick Access Toolbar.
Alternatively, the buzzer can also be silenced by selecting the Settings tab, then set the Buzzer Silent parameter to Disable.
This will turn off the buzzer for the current alarm status, but the buzzer will still sound when the next Fault/Warning condition
occurs.
The buzzer can be disabled permanently by selecting the Settings tab then setting the parameter Buzzer Disable to
Disable. This will disable the alarm so that no alarm sounds for any Fault or Warning condition.
