1.4 Precautions
General Precautions
Read the following carefully before using this product:
The RED250mobile Eye Tracker is a sophisticated measurement
device. Please handle it with care in order not to damage any of its
internal components.
When the RED250mob ile Eye Tracker is not in use, power it off by
unplugging it from the USB port and safely storing it in its case.
Do not scratch the shield (front face) of the RED250mobile Eye
Tracker.
Keep the RED250mobile Eye Tracker away from heat sources.
No part of the product may be modified or rebuilt.
Any usage other than described in this manual is not permitted.
The RED250mobile Eye Tracker may warm up to 55°C
during prolonged operation.
Magnet Precautions
Neodymium magnets (Rare Earth magnets) are used in this device to
connect it to the Mounting Bracket. This allows the RED250mob ile Eye
Tracker to be easily disconnected and safely stored in its case while the
Mounting Bracket stays attached to the Laptop Display or Desktop
Monitor. However, because these type of magnets are extremely strong,
please read the following precautions.
Neodymium magnets are not the same as standard magnets. This
type of magnet can cause injury if not used properly.

Welcome
Page 7
Neodymium magnets have strong magnetic fields and are likely to
cause damage to magnetic media devices. Therefore, keep the
RED250mobile Eye Tracker away from magnetic media such as
hard drives, memory sticks, credit cards, magnetic ID cards, or other
magnetic media. KEEP THE DEVICE IN ITS STORAGE CASE WHEN
NOT IN USE.
While connecting the RED250mobile Eye Tracker to the Mounting
Bracket, the two attracting magnets have enormous strength and can
severely pinch your fingers if they come between the magnets when
they are connecting together.
Gently connect the RED250mobile Eye Tracker to the Mounting
Bracket. Neodymium magnets are prone to cracking if connected too
quickly or if the device is dropped.
Metal items, such a keys, knives, or tools may cause the magnet to
shatter, if placed near enough to the magnets to cause them to
connect with the magnets.
Do not leave the RED250mobile Eye Tracker near an open flame or a
heat source. Aside from destroying the device, the neodymium
magnets may ignite, burn and create toxic fumes.
Do not handle the RED250mob ile Eye Tracker when eating. In the
unlikely event that the magnets come in contact with food, the metal
compounds in the magnets may be toxic when ingested.
Neodymium magnets should NEVER be used near a
person who uses medical aids such as a
pacemaker. The magnet can cause the medical aid to
malfunction. Individuals with pacemakers or internal
medical devices should use caution when handling
the RED250mobile Eye Tracker and the mounting
bracket. Magnetic fields may affect the operation of
these devices. Consult your physician and the

Page 8
manufacturer of your medical device to determine its
susceptibility to static magnetic fields prior to
handling the RED250mobile Eye Tracker and the
Mounting Bracket. All of our magnetic products should
be kept at a safe distance from individuals with these
devices.
Keep Out of Reach of Children NEODYMIUM
MAGNETS (RARE-EARTH) MAGNETS SHOULD BE
KEPT OUT OF REACH OF CHILDREN. RARE-EARTH
MAGNETS ARE NOT TOYS.
Children should not be allowed to handle or play with
rare-earth magnets. Small magnets pose a choking
hazard. Children and adults should not ingest
magnets or place magnets in any body orifice such the
ear, nose or mouth. Ingestion of magnets is very
hazardous. If magnets are ingested or aspirated into
the lungs, immediate medical attention is required.
Swallowed magnets can stick together across
intestines causing serious infections and death. Seek
immediate medical attention if magnets are swallowed
or inhaled. Children under 3 should not handle
magnets, in any case.
Transportation
The International Air Transport Association (IATA) Dangerous Goods
Regulations provide guidelines for the identification, classification, and
testing of potentially hazardous materials offered for transports by air.
IATA Packing Instruction 902 defines the acceptance criteria and
provides packaging guidelines for magnetized material. These
instructions should be consulted prior to transporting magnetic material

by air. These regulations also apply to magnets built in to products such
as the Eye Tracker and Mounting Bracket.
