There are two reset functions, soft reset (warm boot) and hard reset (cold boot).
A soft reset (warm boot) re-boots the device without losing RAM data. You would perform a soft reset 1) when the terminal fails to respond, 2) after installing software applications that require a reboot, or 3) after making changes to certain system settings.
Press and hold the Red Function + ESC keys for approximately five seconds. The screen turns white and the decode and scan LEDs flash for approximately three seconds.
When the reset is complete, the Today screen appears.
A hard reset (cold boot) erases all of the data and applications stored in RAM memory and launches Autoinstall, which re-initializes the terminal.
Press and hold the Red Function + Tab keys for approximately five seconds. The screen turns white and the decode and scan LEDs light for approximately three seconds.
The terminal re-initializes.
When you clean boot the CN3, it loads only those files and programs that are absolutely required by the operating system. Use the clean boot to troubleshoot the CN3 by getting it up and running so that you can perform diagnostic tests to determine which elements of the normal boot process are causing problems.
Press the Power button to suspend the CN3.
Remove the battery pack from the CN3.
With a stylus, press the Reset button on the battery cavity.
Press and hold the Power button as you insert the battery back into the CN3.
Continue to hold the Power button until a Warning message appears on the display.
Release the Power button, read the message, and press either button on the right side to continue.
Wait for the CN3 to load files from the miniSD card.
