KEY FUNCTIONS
Refer to (Figure 1) for key placement.
ON/OFF KEY
The On/Off key activates the unit. During power up, the monitor performs
internal self-tests, illuminates the display, sounds the alarm, and determines
which sensors are connected to the system. Pressing and holding the key
for one second when the power is ON will turn the power OFF, independent
of the screen being displayed.
ALARM CANCEL KEY
During normal operation, selecting the Alarm Cancel key acknowledges
the alarm condition displayed on the screen. Active row alarms are reset
after an ALL ROWS FAILURE condition or a power down-up sequence
occurs. If the error condition continues, the key must be selected again to
cancel the alarm. When no alarms are active, the volume may be modified
by selecting and holding the Alarm Cancel key.
ENTER KEY
The Enter key selects a highlighted item for data modification. After
changing the parameter values, Enter accepts the modified data.
ESCAPE KEY
On the Main Operate screen, select and hold the Escape key for four
seconds to clear an area accumulator if it is located on the top line of the
display.
When navigating through sub-menus, the Escape key moves the user back
one selection. After changing parameter values, selecting Escape accepts
the modified data. The Escape key also serves as an alarm cancel key.
UP AND DOWN ARROW KEYS
On the Main Operate screen, the Up and Down Arrow keys are used to
manually select the parameters viewed at the top of the display. They are
inactive if all parameters are already displayed (number of parameters are
equal to or less than number of lines).
On the Main Operate screen, the arrows are used to navigate between
options. On set-up screens, the arrows are used to navigate between
options or to change a digit/option.
