15 The main menu
In addition to their functions in other opera-
tions (see 15.2
Manual control
), the following
keys have specific actions in menu screens:
STOP
: In general,
STOP
functions as a
"go back" key, taking the user up one
menu level without making a change. In a
numeric entry screen,
STOP
resets the
pump to the previous value.
UP
: The
UP
key is used in menu item se-
lection: it moves a highlight up the menu.
When a numerical entry screen is dis-
played, pressing
UP
increases the number
displayed.
DOWN
: The
DOWN
key is used in menu
item selection: it moves a highlight down a
menu. When a numerical entry screen is
displayed, pressing
DOWN
decreases the
number displayed.

START
key to leave setup and begin the
dose batch via the priming screen. When the priming screen is displayed, press

DIRECTION
: During Dose setup, the
DIRECTION
key reverses the direction of
pump rotation instantly.
RETURN
: The

key functions in a similar way to the "enter" key of a
personal computer: it confirms key-presses made immediately before. In menu
item selection, it triggers the action or display selected from a menu using the
UP
and
DOWN
keys.

.
