b. If the pen arms are vertically aligned as shown in Figure 2-11, do the
following and then proceed to Step 3.
Figure 2-11. Vertical Alignment of Pens (pens can't be inserted)
(The pen arms must be offset sufficiently to allow for clearance before insertion
or removal is attempted. The pens must be moved electrically.)
• Make sure the recorder door is closed and a piece of chart paper is
installed on the spindle on the chart base.
• Turn the unit back on by moving the power switch to "|" and wait for
the pens to be far enough apart to remove a used pen one at a time or
to insert a new pen one at a time.

DO NOT ATTEMPT TO OFFSET THE PENS
MANUALLY (BY HAND). THE DRIVE MECHANISM
COULD BE DAMAGED. DO NOT ATTEMPT TO
CHANGE THE PENS WHILE THEY ARE IN MOTION.
• Turn off the unit (PWR switch position in "O" position) to stop the pen
movement.
3. Open the recorder door by applying downward pressure on the latch button
(refer to Figure 1-1, item #16).
4. Remove the pens from the package and the cap from each pen.
We recommend that you put the pen caps on special posts located on the chart
base of the recorder near the light bulbs. Figure 2-12 shows the location of the
posts.
