for other error messages that might appear on the second line of

the display.

automatically power-up the Test Set in a different state. Press the

Preset key before proceeding; this will restore the Test Set to the

factory power-up condition.

❏ The Autostart Test Procedure on Power-Up: field (of the

“TESTS [Execution Conditions]” screen) is set to On to

automatically run a loaded program. Press the
