About the power lock function

By enabling the power lock function, the MDNC-3421 is forced to remain switched on. This means that it can’t be switched to stand-by mode manually until the power lock function is disabled again.

To enable/disable the power lock function:

1. Bring up the OSD main menu.
2. Navigate to the Configuration > User Interface > Controls menu.
3. Enter the Power Lock submenu.
4. Select Enabled/Disabled as desired and confirm.
