5.2 Initializing the working memory
With this diagnostic step the default values for instrument parameters
can be entered via the keypad and the instrument returned to its origi-
nal condition. This measure is important with respect to the following:
In rare cases it could happen that massive interference signals such
as current peaks, lightning, etc. could affect the contents of the data
memory. If the data memory contents are undefined then this could
lead to a system crash.
The Sample Processor has different ways of initializing the working
memory. Either the complete data memory ( all ) or only parts of it (pa-
ram, config, setup, assembly ) can be overwritten with the default
values.
Although the instrument number is retained, initialization should only
be carried out when absolutely necessary, as this deletes the stored
user data (etc.).
• Keep key <9> pressed down when the instrument is switched on.
