Pressing the MODE key will abort the EDIT routine, return you to the first MODE

General Information
The Lambda DG-4 controller will accept a sequence of up to 32 FILTER NUMBER values
into its non-volatile memory as part of the “RING BUFFER”. This sequence of FILTER
NUMBERS can then be “played back” during an experiment. It is possible to program a total
of 64 FILTER NUMBER values into the RING BUFFER but the additional 32 values are
stored in a volatile memory and will be lost if the Lambda DG-4 is turned off or RESET.
The values in the RING BUFFER can be stored and viewed while in any operational mode
but it can only be RUN from one of the “triggered” operational modes since the filter
changes are dependent on a STROBE PULSE or SYNC PULSE.
