Option selections using the display switch

annunciator, and the Control Status display). It has a central rest
position,
OPER

allows you to get into Option Selection
mode, scroll through various portions of the menu, and scroll
through digits and characters to set values.
SELECT
allows you to
select which area to access and to set values and characters.

want.

SELECT
. You are now

complicated, but once you have done it a few times, it will
seem very logical.
It is suggested that you now proceed to try it intuitively. The indi-
cators will help you, and you may not need to use the manual. If
you do run into trouble, consult the following sections.
