6 Important Information

6.1 Electrical Safety

WARNING: The Host PC, and all peripherals connected to it with cables, should
be positioned out of reach of the participant (at least 120 cm away). Only
devices included with the system and clearly identified as suitable for contact
with the participant (such as a response device) should be within the
participant's reach.
WARNING: The operator should avoid simultaneously contacting the
participant and the computer, or any device connected with cables to the Host
PC, such as a keyboard or mouse, that were not included with the system and
clearly identified as suitable for contact with the participant.
WARNING: If exposed sections of the USB cable are damaged, a shock hazard
to the participant may exist. Remove the unit from service immediately if such
damage is found.
WARNING: This unit is drip-proof and spill-resistant; it is not watertight or
waterproof. Any exposure to substantial quantities of fluids carries risk of
danger to participants. Unit should be taken out of service IMMEDIATELY after
immersion or substantial spill onto unit, and unit should be returned for
inspection and repairs.
WARNING: Cleaning with a wet cloth, sprays applied directly to unit, or pouring
fluids onto the EyeLink Portable Duo eye tracker could cause a shock hazard to
participants, by forcing water into the unit. Units returned with signs of such
misuse will not be covered under warranty.
WARNING: After contact with any running or dripping liquid, let the unit dry
thoroughly before allowing participants near it with the USB cable connected. If
fluid has puddled in any area of the unit, (such as below the window), clean
and dry the unit and return it for repair and inspection.
Class II Equipment — No protective earth connection required.
