Warning: Do not lift the pen arm(s) in order to slide a new chart under the pen(s). This will remove the bend in the arm and will no longer provide enough downward pressure for the pen(s) to draw a legible mark.
Press and hold the "change chart" button (#3) on the membrane switch for approximately one second until the pen begins to move to the left and then release the button. Wait until the pen has moved onto the pen lift ramp (if available) or near the edge of the chart paper and stops. To remove the chart paper, unscrew (counter-clockwise) the chart "hub" knob , located at the center of the chart. Remove the old chart paper and position the new chart o that the correct time line coincides with the time line groove on the chart plate.
Re-attach the chart "hub" knob and screw securely (by hand) against the chart. Note: over tightening the chart "hub" knob can damagte the gears in the chart motor gearbox assembly. Press and hold the "change nchart" button (#3) again for approximately one second until the pen begins to move back onto the chart and then release the button. Check to make sure that the pen is marking on the chart paper. If it is not, then carefully adjust the pen arm to establish contact with the paper. (Please see "How to adjust my pen arm" in the Recorder section of FAQ.
