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.
