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.
