VM700A Option 01 (NTSC) & Option 11 (PAL) User Manual

9-9

The VM700A displays the message:

* Ć* ĆINITIALIZING IN QUICK START MODE Ć* Ć* Ć

then proceeds with system initialization.

To bypass individual diagnostics running at power up, touch the Abort softkey

when the diagnostic is running. The VM700A proceeds to the next diagnostic

selected in the Diagnostics~Selection file. If you abort the last selected diag-

nostic, the VM700A proceeds with system initialization.

Individual Diagnostics and Measurements

Individual diagnostics and diagnostic measurements can be run at any time.

To run an individual diagnostic or measurement:

1. Press the Measure button

2. Touch the Diags softkey (if the diagnostics directory is not already

displayed)

3. Touch the icon of the diagnostic or measurement you want to run

Diagnostic measurements simply display the value of the item they are

measuring until you press a front-panel button. Individual diagnostics, however,

have a few more options. When running, individual diagnostics behave as

follows:

1. The display shows the name of the diagnostic, the message SELECT RUN

MODE, and two soft keys labeled PowerUp Mode and Interactive Mode.

2. Touching PowerUp Mode runs the diagnostic in the same way as if the

machine were powering up. There is no user interaction, and each line

written to the display summarizes the results of a group of tests. A softkey

appears at the bottom of the display to allow you to change the Run mode

while the diagnostic is running, if you so choose. When the diagnostic is

complete, the SELECT RUN MODE screen appears again. Press the

Measure button to select a different diagnostic or Measure-mode measure-

ment. Press any other major mode button to put the VM700A into a different

mode.

3. Touching Interactive Mode runs the diagnostic, one group at a time. Results

of individual tests, as well as a summary for each group of tests, appear on

the display. Four soft keys, labeled Continue, Loop On Test, Rerun Test,

and Change Run Mode, respectively, appear at the bottom of the display.

Continue runs the next group of tests.
