•
If dirt is found, follow the cleaning instructions in section 5.2 of this
document. If the window is deeply scratched or cannot be cleaned, return
the unit for repairs.
2)
USB Cable (Weekly):
•
Check any exposed parts of the USB cable for cuts or nicks in the cable
jacket.
•
Any damage within 120 cm of the participant will compromise the
electrical safety of participants, should they come into contact with
exposed cable interior wiring. If such defects are found, and especially if
bending the cable shows any silver shield wire, the unit should be taken
out of service IMMEDIATELY and returned for repairs.
3)
Illuminator (Weekly, or if eye tracking issues are present):
•
Inspect the illuminator LEDs for even brightness.
•
Turn out the room lights and look at the right side of the optical window
of the EyeLink Portable Duo
•
Operators who are red-green color-blind should not perform this
inspection, as they are less sensitive to near-infrared light; instead, use a
digital camera or a cell phone camera.
•
The illuminator will show the 6
×
6 grid of LEDs clearly as red dots.
•
If these are seen, return the unit immediately for repairs.
5.2 Cleaning and Disinfection
WARNING:
Cleaning with a wet cloth, sprays applied directly to unit, or pouring
fluids onto the EyeLink Portable Duo could cause a shock hazard to
participants, by forcing liquids into the unit. Units returned with signs of such
misuse will not be covered under warranty.
WARNING:
After cleaning or disinfecting with any liquid, or if the unit is
exposed to any liquid, let the unit dry thoroughly before allowing participants
near it with the USB cable connected. Inspect unit and cable where accessible
to participant before reconnecting.
Do not perform any cleaning (other than wiping with dry cloth) while a
participant is using the equipment. Participant should remain at least 120 cm
from the unit while any other cleaning is in progress, and should not return
until unit has dried completely.
Use only the approved products and methods in this section for cleaning and
disinfecting the eye tracker. Any other cleaning or disinfection products may
damage the unit, or compromise participant safety, and such damage will not
be covered under warranty. Table 2 lists several such cleaning hazards and safe
alternatives.
