The sequence pattern is 26 pointer movements followed by 1
missing pointer movement. The added adjustment occurs 2 ms after
the 13th pointer adjustment. Pointer polarity is selectable and the
time interval between pointer adjustments programmable to 200
ms, 500 ms, 1 s, 2 s, 5 s or 10 s. Added adjustments occur every 30
seconds or every repeat of the 26-1 pattern, whichever is longer.
An 87-3 pattern is selected. The sequence pattern is 87 pointer
movements followed by 3 missing pointer movements with a
cancelled pointer movement at the 87th pointer. Pointer polarity is
selectable, and the time interval between pointer adjustments can
be set (see Note 1). Cancelled adjustments occur every 30 seconds or
every repeat of the 87-3 pattern, whichever is longer.
