Installing/replacing chart procedure
Follow the procedure in 90HTable 5-1 to install/replace the chart.
Store replacement charts in a dust-resistant location. Otherwise, accumulated dust on the
chart may cause excessive pen tip abrasion which can shorten expected pen life. In addition,
you may want to air purge the case if the recorder is mounted in an extremely dusty
environment.
