1 - 8 WT4070/90 Wearable Terminal Integrator Guide
To save battery power, set the wearable terminal to turn off after a specified number of minutes.
Configuring the Wearable Terminal
•
To customize the wearable terminal settings, refer to the Microsoft Applications for Mobile and CE 5.0 User 
Guide.
•
To set up ActiveSync to synchronize the wearable terminal with the host computer, see Chapter 3, 
ActiveSync.
•
To configure the wearable terminal for wireless LAN network, see Chapter 5, Wireless Applications.
•
To deploy software on the wearable terminal, see Chapter 7, Application Deployment.
Resetting the Wearable Terminal
There are two reset functions, 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 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 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). Never perform a cold boot unless a warm boot does not solve the 
problem.
To perform a cold boot on a WT4070/90 press and simultaneously hold the Power button and the 
1 and 9 keys. Do 
not hold down any other keys or buttons. The wearable terminal initializes.
To perform a cold boot on a Voice Only WT4090 press and simultaneously hold the P1 and P2 keys, and the 
Power button. The Voice Only WT4090 initializes.
