Data/Signal.
• All Positive Transition Filter registers are initialized to all ones: Communicate,
Hardware #1, Hardware #2, Operation, Calibration, Call Processing and Questionable

Front-panel PRESET Key
The Front-panel Reset is accomplished by pressing the PRESET key on the front
panel of the Test Set.
For the CONFIGURE, PRINT CONFIGURE, TESTS (Execution Conditions),
TESTS (Printer Setup) and I/O CONFIGURE screens,
Table 29 lists the fields
which are restored/initialized when the front-panel PRESET key is pressed. The
restored state or initialized value is listed below the field name. Fields which are
not listed are maintained at their current value, whatever that may happen to be.
All fields in the TESTS (Main Menu) screen and the TESTS (External Devices)
screen are maintained at their current state/value. The current state/value of the
maintained fields can be ascertained programmatically.
