Keypad Lock Feature
There is a Keypad Lock feature that users can enable from the

one of the navigation keys, as shown below.
If the keypad is locked, you must unlock it before you can enter the
Menu. To unlock the keypad and enter the menu, you must first hold
the Right button for 5 seconds. An audible indicator sounds when
the keypad is successfully unlocked. Once the display is unlocked,
you can enter the Menu as you normally would by pressing the Up
button.

inactivity time-out period. After
you have unlocked the keypad
as indicated, the keypad will
re-lock after five minutes of
inactivity to prevent someone
from accidentally pressing a
button and changing any of the
settings.
Note: When Keypad Lock is
enabled, the Left, Right, and Up/
Down buttons are locked while
the ventilator is turned on. The
Alarm Indicator/Audio Pause

to function normally.
