Welch Allyn RETeval-DR, Directions For Use Manual

Page: 32 / 60

Note
At the beginning of each test, the device automatically
recalibrates the light intensity and color, during which time
the patient will see brief red, green, and blue flashes. This
process takes about one second. If recalibration is
unsuccessful, an “Unable to calibrate” or “Excessive
ambient light” error will display. See “Troubleshooting” for
suggestions to resolve this issue.
7. Wait while the device conducts the test.
The device provides feedback on the device display to the clinician on the progress
of the testing. Communicate this progress with the patient as it occurs.
8. After the device has indicated that the testing is complete, disconnect the lead from
the sensor strip.
9. Repeat Steps 1–8 to test the opposite eye.
10. Clean the eyecup, sensor strip lead, and other patient-contact parts of the device
after each patient.
A results summary is shown on the device. While the results are being shown, the data
is saved in the device. A Next button and notification of successful storage appears upon
completion of the save, which can take several seconds.
Remove the sensor strips
1. Remove the sensor strips from the patient’s face, starting with the end under the
eye. Alternatively, ask the patient to remove the sensor strips.
2. Dispose of the sensor strips in accordance with local guidelines.
