Resetting your Motorola WT4090
There are two types of resets, warm boot and cold boot. A warm boot restarts the wearable terminal by closing all running programs.
A cold boot also restarts the wearable terminal, but erases all stored records and entries in RAM. Data saved in flash memory or a memory card is not lost. In addition it returns formats, preferences and other settings to the factory default settings.
Perform a warm boot first. This restarts the wearable terminal and saves all stored records and entries. If the wearable terminal still does not respond, perform a cold boot.
Performing a Warm Boot
Hold down the Power button on your Motorola WT4090 for approximately five seconds. As soon as the wearable terminal starts to perform a warm boot release the Power button.
Performing a Cold Boot
A cold boot restarts the wearable terminal and erases all user stored records and entries that are not saved in flash memory (Application and Platform folders).
To perform a cold boot on a WT4070/90 press and simultaneously hold the 1, 9 and Power button. Do not hold down any other keys or buttons. The wearable terminal initializes.
Note: Never perform a cold boot unless a warm boot does not solve the problem.
