Operation 3-11
False Negative and False Positive catch trial presentations are indicated by the symbols (+)
& (-) on the operator LCD so they can be distinguished from regular teststimulus
presentations.
Note: You can PAUSE or RE-START the test by pressing the GREEN Button at any time
during the test. Follow the Operator LCD Display instructions to CONTINUE TEST or to
RE-START TEST from a pause . The patient can also PAUSE the test (for a break, etc.) by
simply pressing and holding down the Patient Response Button . The test will resume
automatically once the patient releases the Patient Response Button. During patient
pause, you may also select OPERATOR PAUSE (GREEN Button) so that the test will
remain paused until you restart it.
Note : A SCREENING C-20 TEST takes less than 1 minute (per eye) to complete, a
THRESHOLD C-20 TEST takes approximately 4 minutes (per eye) to complete and a
THRESHOLD N-30 TEST takes about 4-1/2 minutes.
At the end of the right eye test, the Operator LCD Display will prompt for a left eye test.
Slide the Patient Visor to the left eye test position (this is to your left when facing the
patient from the operator’s side). Prepare the patient. Select RUN SCREENING C-20 TEST
(TOP Operator Button), RUN THRESHOLD C-20 TEST (2nd Operator Button from the top), or
RUN THRESHOLD N-30 TEST (3rd Operator Button from the top) from the LEFT EYE TEST
MENU to begin the left eye test immediately after a momentary check for proper
calibration.
Note: To skip the left eye test, select SKIP LEFT EYE (Bottom Operator Button) to
proceed to the results menu.
