Key Description
Power (red) Turns the MC9190-G on and off.
Performs a warm boot and a cold boot. See
Resetting the MC9190-G on page 2-22
for information
about performing a warm and cold boot.
Green/Red Dot To use a key as an application key (APP key) on the keyboard, a new keyboard remap table must be
created and installed. However, the Green/Red dot keys can be remapped as APP keys through the
registry.
Create an XML Provisioning file with the following entries:
Characteristic type =“HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\KEYBD”
Parm name = “GreenKeyOverride” value = “xx”, where xx is the new APP key code.
Parm name = “RedKeyOverride” value = “xx”, where xx is the new APP key code.
Refer to the MC9190-G Integrator Guide for instruction on updating the registry using XML
Provisioning.
This sends an APP key code, instead of their original key codes, when the green or red dot key is
pressed.
Scan (yellow) Activates the scanner/imager in a scan enabled application.

Application These keys can be assigned to an application.
On Windows Mobile 6.5 devices: F6 and F7 keys cannot be remapped and are dedicated by the
Operating System to control volume level. When these keys are pressed, Shell.exe traps them and
displays the volume adjustment window. To get these keys to an application, call GXOpenInput() at the
beginning of the application and call GXCloseInput() at the end of the application. This redirects all of
the key events to an application, including the F6 and F7 keys.
Note: Other applications cannot receive any key event until GXCloseInput() is called. For example, if
the customer is using the APP1 key to run Calc.exe, this is disabled during this period.
