Basic Operation
The MENU key opens a shortcut window of common
functions. The content of this window is context sensitive to
the screen that is currently active but will always show the
following five choices:
1. Home
2. Save Job
3. Job Manager
4. Copy/Move Utility
5. Take Screenshot
Home provides a shortcut to the home screen (preventing
repeated presses of the QUIT key)
Save Job saves the current job. This is particularly useful if
the auto-save function has been turned off and a job needs
to be saved partway through the cable test schedule. The
currently active job file is always displayed in the top left
corner of the display.
Job Manager and Copy/Move Utility provide a shortcut to
these two File Management Utilities.
Take Screenshot saves the current screen to the internal
memory as a .png file. Screenshots can be transferred from
internal to external memory using the copy/move utility.
