The function button command selection at the bottom of the DMT Test Setup Menu consists of five options
available to the operator. The first three options (EDIT/SELECT, SELECT PREVIOUS, SELECT NEXT)
enable the modification of the test parameters (residing near the upper part of the screen). The last two
options at the bottom of the screen are CABLE TESTS and MAIN MENU. For some options for which a
numeric value must be entered, only three options may appear: EDIT/SELECT, CABLE TESTS and MAIN
MENU. To modify a test parameter, it must first be highlighted with the cursor. A
test parameter can be
highlighted by moving the cursor to the desired parameter with the Cursor Pad UP/DOWN arrow buttons.
