Generic Functions
There are two additional functions which influence the working of your whole MC-1.2:
Front Panel lock out + LED shut down
When pressing both front panel keys together at one time, all LEDs will shut down except the »POWER« and »LOCK« LEDs.
Additionally, the functions of both keys are also blocked to prevent unauthorized operation, which is important during e.g. live
events.
During that state of operation, pressing only one of both keys let every appropriate LED light according the device‘s settings as
long as the key is pressed. Thus, you can check easily the device‘s settings without unlocking the device finally.
To reactivate the keys and the LEDs, please press both keys for apperox. four seconds until all LEDs light again.
Factory Reset
You can reset the operating system of your MC-1.2 to the initial status by switching on the unit while pressing the »MENU«
key simultaneously.
