Helpful Hints
•
No activity on the vision screener—After 60 seconds the screen will dim; after 5 minutes the
screen will automatically turn black to conserve battery power. Tap the screen to ‘wake up’ the
vision screener or press the power button. If the screen does not light up, plug in the power
cord and try again.
• Exporting/Delete Historical Records—Verify you have successfully exported desired data to a
USB drive before you select “Delete All Records”.
•
Routinely Delete ALL Records from the vision screener—Go to the History screen and select
Clear All icon. Select “Delete All Records”. You may also delete all Queued records.
• Avoid Powering Off during a Screening—Once the screening takes place, exit by selecting the
button, then power down the device normally.
•
Input Screen—Holding down the button on any input (keyboard) screen will delete all
data from the field.
•
Low Battery—When the battery level reaches a very low level, a notice will appear to the User
indicating they should insert the power cable or the device will shut down. If no power cable is
inserted, the device will automatically shut down due to low voltage of the battery.
