4.1 Navigating the Menu Screens
To navigate through all of the menu screens and settings:
• Use the Up/Down button to scroll through the menu.
• Use the Left and Right buttons to perform the actions specified on the on-screen buttons.
4.2 Using the Keypad Lock Feature
Note: When Keypad Lock is enabled, the Alarm Indicator/Audio Pause and Start buttons continue to function
normally.
1. Access the Keypad Lock feature from the Options menu. It is intended to prevent accidental changes to device
settings. This feature locks the navigation keys (Up, Down, Stop, Left, and Right).
2. If the keypad is locked, you must unlock it before you can enter the Menu. When you press one of the navigation
keys, a Keypad Unlock message displays. To unlock the keypad, hold the Right button down for 5 seconds. Or press
the Left (Cancel) button to cancel the Keypad Unlock action.
3. 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.
Note: There is a keypad lock inactivity time-out period. After you have unlocked the keypad as indicated, the
keypad will re-lock after five minutes of inactivity.
The keypad automatically unlocks if an alarm or informational message occurs and remains unlocked while alarms are
active.
4.3 Accessing the Standby Screen
1. After you press the button, the Startup screen appears momentarily, indicating the device name and software
version.
2. The Standby screen then appears, example shown here. It displays the date and time, therapy mode, a patient
accessory panel (if a patient accessory is attached), a status panel, and the soft key panel.
