The Preset display will ask “Unlock?”
2. Press TAKE.
The PROT/LOCK button lamp will switch to “low” green.
If the TAKE command is ignored, the output has been locked by another panel. To find out the name of the panel, select
an input button.
An output may be forced unlocked, no matter which panel locked it, if the password level of the unlocking panel is level 90
or greater. The password level is defined in the MPK Devices table entry (page 5−109). This operation is useful for a master
panel capable of switching any source to any destination. The operator would be required to force unlock the output prior
to changing its source selection.
