Pointer Sequence	Description
T1.105 A3 PHASE	Phase transient pointer adjustment burst test sequence. All
TRANSIENT	adjustments are of the same polarity, which is selectable. The
GR-253 5031	interval between bursts is fixed at 30 seconds. Each burst consists
	of 7 pointer movement. The first 3 in each burst are 0.25 s apart,
	and the interval between the 3 and 4 movement, and each
	remaining movement 0.5 seconds.
T1.105 A4 PERIODIC	An 87-3 pattern is selected. The sequence pattern is 87 pointer
NORMAL (87-3 Pattern)	movements followed by 3 missing pointer movements. Pointer
GR-253 5-33(b)	polarity is selectable and the time interval between pointer
	adjustments settable.
T1.105 A4 PERIODIC	Provides a continuous sequence of pointer adjustments. The
NORMAL (Continuous	polarity of the adjustments is selectable, and the time interval
Pattern) GR-253 5-34(b)	between adjustments can be set (see Note 1).
GR-253 5-32(b)	This selection is only available if you have selected VT1.5 mapping.
PERIODIC NORMAL (26-1	The sequence pattern is 26 pointer movements followed by 1
Pattern)	missing pointer movement. 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 seconds.
T1.105 A5 PERIODIC ADD	An 87-3 pattern is selected. The sequence pattern is 87 pointer
(87-3 Pattern)	movements followed by 3 missing pointer movements with an added
GR-253 5-33(c)	pointer movement after the 43rd pointer. The spacing between the
	added adjustment and the previous adjustment is set to the
	minimum. Pointer polarity is selectable. The time interval between
	pointer adjustments can be set (see Note 1). Added adjustments
	occur every 30 seconds or every repeat of the 87-3 pattern,
	whichever is longer.
T1.105 A5 PERIODIC ADD	Periodic Single adjustments, with selectable polarity and added
(Continuous Pattern)	adjustment (1 extra). The spacing between the added adjustment
GR-253 5-34(c)	and the previous adjustment is set to the minimum, (see Note 2).
	The time interval between pointer adjustments can be set (see Note
	1). Added adjustments occur every 30 seconds or every repeat of the
