Directions for Use Overview of Monitor Operation 23
Timing Out the Display and the Back Light
To conserve battery run life, the monitor can be configured to turn off the display and the
back light if no operator activity (that is, a button press) is detected for a specified number
of minutes.
• When the display is off, no patient data is visible.
• When the back light is off, patient data is visible only under direct light.
The monitor configuration determines whether the time-out feature is enabled or
disabled, and defines the default time-out period if it is enabled. If the feature is enabled in
the configuration, you can temporarily change the time-out period or disable the time out
through the Setup -> Timings menu.

Buttons To prevent unauthorized use
Back Light To extend the battery run life

information on enabling or disabling lock-outs for these elements, see “Monitor
Configuration” on page 111.
