Operating instructions
[10] READY/SAFE Switches/Indicators These 2-position switches are provided for setting individual channels in
Record Ready or Record Safe mode. The red indicators above illuminate
when that READY/SAFE switch is set to READY, indicating that the
corresponding channel is ready for recording. The READY/SAFE switches can
be overridden by the ALL SAFE switch [11].
NOTE: There is a functional interaction of the READY/SAFE switches [10] and
the output select switches. The output status and indicator indicators also
change in some cases, as noted, when the machine is switched between Stop
and Play modes.
[11] ALL SAFE Switch/Indicator This switch is used to select between putting all channels in Record Safe
mode all at once or allowing the mode to be selected by the READY/SAFE
switches [10] on the individual channels.
❑ Setting this switch to the ALL SAFE position puts all channels into
Record Safe mode and illuminates the adjacent red ALL SAFE indicator.
In All Safe mode, the individual READY/SAFE switches for each channel
have no effect and the indicators above them should be off.
❑ When ALL SAFE is not selected, the Record Ready status of each
channel is determined by its READY/SAFE switch.
