6.1 Error messages
If an error occurs, execution of the active command is aborted and an error
message is displayed (display blinks). This must be confirmed with the
<QUIT> key.
If the changer was processing a sample series when the error occurred, it
then switches to 'HOLD' state. After the cause of the fault or error has been
remedied, the sample series can be continued by pressing key <START>
with the next command in the current sequence. If the fault or error cannot
be remedied, the current method can also be aborted with <STOP>.
List of the possible error messages and their causes:
∗ battery low The battery for non-volatile storage of the user data must be
replaced.
