LOCKED

In LOCKED mode the rotary controls or the entire unit are protected against improper use by
means of locking.
Locking the "SYSTEM CONTROL" rotary control
The "SYSTEM CONTROL" rotary control is locked by pressing it (for longer than 2 seconds).
The "LOCKED" and "LEVEL" LEDs will light up. Turning the rotary control allows you to review
all the channel settings, but only the setting of the input and output levels can be changed. All
other functions are locked against input. Briefly pressing the control in LEVEL mode allows the
display to be toggled between VU meter and setting mode.
Pressing the "SYSTEM CONTROL" rotary control for longer than 1.5 seconds removes the
locking. The rotary control will be positioned in the default setting "LEVEL".
Locking the entire unit
The entire unit can be completely locked by simultaneously pressing the "SYSTEM CONTROL"
and "OUT MASTER" rotary controls (for longer than 2 seconds). The original settings will be
saved. The "LOCKED" and "LEVEL" LEDs will light up. Turning the rotary control only allows
you to review all the channel settings. All functions are locked against input. Briefly pressing
the control in LEVEL mode allows the display to be toggled between VU meter and setting
mode.
Pressing the "SYSTEM CONTROL" and "OUT MASTER" rotary controls for longer than 1.5
seconds removes the locking. The "SYSTEM CONTROL" rotary control will be positioned in the
default setting "LEVEL".
Exempting individual channels from the locking
If the entire unit has been locked, as described above, individual input channels and the "OUT
MASTER" channel can be exempted from the locking. The excluded channels can then only be
adjusted in volume. Pressing the rotary control of the desired channel (for more than 2
seconds) excludes the channel from the locking. Pressing the control again (for longer than
1.5 seconds) relocks the channel.
The set LOCK states are retained even after switching the DMM 4/2/4 off and on again!
