Adjust the Auto Backlight Off Settings for Manual Mode
Use FieldLab Desktop to control the amount of time that the backlight stays on before shutting off automatically to conserve battery life.
Each Test Mode has its own Auto Backlight Off settings. When you Activate a Test Mode on the FieldLab, whatever the settings are for in that Test Mode will apply to the FieldLab as long as that Test Mode is active.
