6.0 Controls and Indicators
(See Figure 1.0 and refer to Table2.0)
The controls and indicators of the ATO-250
are shown in a control-panel illustration in
Figure 1.0. The pointing leader lines refer to
each item in the figure with an index
number. Each index number is cross-
referenced to a functional description in
Table 2.0. Although the purpose of these
controls and the display may seem obvious
and intuitive, users should become familiar
with them before attempting to use the
ATO-250. Misuse of the ATO-250 controls
can create serious hazards and cause loss of
data, and equipment damage. First-time
users should also review and become
familiar with the Safety Summary located in
the front section of this manual.
