When the ion level alarm is output,
removing the cause of the alarm can
restore the normal state. One way of
restoring the normal state is to
perform maintenance on the electrode
probe.
For details on electrode probe
maintenance, see
"Performing
Maintenance on the Electrode
probe"(page 9).

one of the two available restore
methods depending on the cause of
alarm output.
