The "SmartDocs" bar can customize this page to show only the features present on a particular Zebra device.
OSX, MX and Android version information for a device can be found in the Android Settings panel or by querying the device through ADB, EMDK or the MX CSP. More info.
The Display Manager (DisplayMgr) provides control of certain display screen features on the device.
Controls whether a device can use Android's built-in screen capture capability, which captures the contents of the screen and saves it to a file on the device.
Note: The method of capturing the screen generally involves a combination of simultaneous key presses that varies from one device to another.

Used to set the length of time the device waits during periods of inactivity (without screen touches or key presses) before turning off the screen to conserve power. Ideally, this interval should represent a balance between battery preservation and user convenience.
Note: Android supports only the display-screen timeout settings shown in the table below. Entering a value between any two supported values will change the setting to the closest supported value. Entering a value outside the minimum or maximum shown causes an error in the Result XML document and the setting change is ignored.

Controls whether a device display can be made blank when triggered by the signal set in the Screen Blanking Signal parameter. Blanking the screen blocks all user interaction with the device and its apps.
This feature was developed for safety reasons and is intended for use with vehicle-mount computers while the vehicle is in motion. It can be activated, for example, by an electrical signal wired to the vehicle accelerator. For more information about connecting a Zebra device to vehicle wiring, please refer to the Integrator Guide that accommpanied the unit.

| 2 | When Triggered by Signal | Enables the screen to be blanked when triggered by a signal external to the device. |
MX: 7.1+ |
Used to enter which external signal will control Screen Blanking, if enabled. Inputs 1 and 2 correspond to serial ports 1 and 2 on the Zebra VC80x vehicle-mounted computer. Other devices might differ. The serial port can be used to determine whether the vehicle’s accelerator pedal is pressed. For more information about connecting a Zebra device to vehicle wiring, please refer to the Integrator Guide that accommpanied the unit.
