TESTING
5-10
You have several options while a test is in progress.
PAUSE
This button halts the test and allows the patient to rest. The patient can also pause the test by
continuously holding down on the response button.
Once in the pause mode, you may choose to resume the test, display the current test parameter
settings, change the fixation monitoring system, change the test speed, or cancel the test.
If you cancel the test while in the Pause mode, all data collected up to that point will be deleted
and the program will return to the Start of Test screen. Non-standard parameters will be
retained, if originally chosen. Before the instrument deletes the data, you will be asked to
confirm your request.
DISPLAY STATUS
This feature is available to you during testing so that you can verify the current parameter
settings.
FIXATION
This button gives you the option of changing the fixation monitoring during the test. Gaze
monitoring cannot be initiated once the test has begun.
TEST SPEED
During testing, the instrument automatically adjusts the test speed based on how quickly or
slowly the patient responds to the stimuli. Nevertheless, if you observe that the pace is too fast,
the TEST SPEED button will allow you to slow the test manually. Press the SLOW button to
change the pace of the test program. The test speed will reset to normal at the completion of
the test.
CANCEL TEST
This choice will discontinue the test, delete all results, and return you to the Start of Test
screen. Non-standard parameters will be retained, if originally chosen. Before the instrument
deletes the data you will be asked to confirm your request.
