CHART REPLACEMENT Note: For recorders with status levels K13 or higher, if the cassette type (i.e. roll or z-fold) is changed, or if the recorder loses its configuration, the recorder must be reconfigured for the correct cassette type (Instrument configuration) or the chart drive will not operate correctly. Before changing the chart, carry out a pen park/fan as described in section above. Once the chart replace-ment is complete, carry out an alignment procedure as described in sections and below.
