Enhanced Write Filter

The Enhanced Write Filter (EWF) is a feature within the operating system of the
MobileView 2711T terminal. When EWF is enabled, the system volume within
the operating system is write-protected, which provides an additional level of
robustness for the operating system.
Before you configure applications on the MobileView 2711T terminal, verify
that EWF is disabled. On the terminal-desktop task bar, the EWF status icon is
unlocked
when EWF is disabled.

to be frequently connected and disconnected from junction boxes.
