o
I
In order not to lose any settings that have been made, proceed in the
following order to switch off the CMU:
! Remove any storage medium from the PCMCIA interface or floppy disk
drive.
! Shortly press ON/STANDBY to initiate the shutdown process and save
the current data to the internal hard disk.
! Wait until the shutdown process has been terminated before setting the
mains switch at the rear to the 0 position.
Note: Instruments equipped with a Front Module controller FMR 6
display the message Shutdown in Progress after the
ON/STANDBY key has been pressed. Keeping ON/STANDBY
pressed for about 4 s on those instruments initiates a
hardware shutdown where data may be lost.
