Set the chart time manually by inserting a coin into the groove in the chart hub and turning clockwise until the correct
hour (and day if applicable) on the chart is referenced to the timing arrow (just to the right of the pen tip on the dial).

The following feature should be used for fine adjustments only.
To adjust the chart time, press and hold Adjust-Up and Adjust-Down buttons located on the back of the unit next to
the dip switch (See Button Operations below).
The green LED will blink rapidly for about five seconds, and then the LED will remain solid green. While in this state

Chart Adjust Mode once Pen Home is pressed. Press Pen Home to move the pens back onto the chart.

longevity, the location should be a clean environment, free from dust and corrosive fumes. Do not exceed temperature
