When A V 1 and AV2 are pressed simultaneously,
the machine goes into the program write mode.
Once in the program write mode, the clock display
on the monitor disappears and the " S T E P - W 1

pressed simultaneously again, the program write
mode ends and the machine returns to the original
state.
{AT • 1 /AT)
If the AT-1 /AT switch is pressed, the LED lights and
the machine enters the AT mode. When the switch
is pressed again, the machine enters the VAT mode
and, when pressed a third time, the LED goes off and
the machine enters the CURSOR OFF mode. After
going to A V 1 or AV2 from the 1/AT mode, pressing
the A T - 1 / A T switch will enable the MAT mode.

T R A C K :
When the T R A C K I N G s w i t c h is pressed, the LED
goes on and the machine enters the T R A C K I N G
mode. When pressed again, the L E D goes off and
the machine enters the normal C U R S O R mode. If
the cursor measurement is turned off while the
T R A C K I N G mode is ON, the T R A C K I N G LED goes
off; however, the T R A C K I N G mode is re-renabled
if the cursor measurement is turned on again. In
the T R A C K I N G mode, A R E F control cause A R E F
and Acursor to move in parallel (i.e., cursor meas-
urement value remains as is). If either A R E F or Acur-
sor comes to the edge of the monitor, movement
of both is halted. Acontrol allows Acursor to be
moved independently (i.e., cursor measurement
value changes).
A T • 1/AT + T R A C K :
When the A T • 1/AT and T R A C K s w i t c h e s are
pressed simultaneously, the machine enters the
Program Readout mode. In the Program Readout
mode, the monitor clock display disappears and the
" S T E P - R 1 " display lights up. When the A T • 1 / A T

again, the Program Readout mode ends, and the
machine returns to the original state.

Clockwise rotation shifts the cursor up or to the right.
Counterclockwise rotation shifts it down or to the left.
In the delayed s w e e p mode, this control is used for mov-
