Observe the following precautions during installation,
operation, maintenance, and repair of the instrument.
Failure to comply with these warnings, or with specific
warnings elsewhere in Agilent manuals, violates safety
standards of design, manufacture, and intended use of the
instrument. Agilent assumes no liability for customer failure
to comply with these precautions.
Persons with implanted or attached medical devices such as
pacemakers and prosthetic parts must remain outside the 5-gauss
perimeter from the centerline of the magnet.
The superconducting magnet system generates strong
magnetic fields that can affect operation of some cardiac
pacemakers or harm implanted or attached devices such as
prosthetic parts and metal blood vessel clips and clamps.
Pacemaker wearers should consult the user manual provided
by the pacemaker manufacturer or contact the pacemaker
manufacturer to determine the effect on a specific
pacemaker. Pacemaker wearers should also always notify
their physician and discuss the health risks of being in
proximity to magnetic fields. Wearers of metal prosthetics
and implants should contact their physician to determine if
a danger exists.
Refer to the manuals supplied with the magnet for the size
of a typical 5- gauss stray field. This gauss level should be
checked after the magnet is installed.
Keep metal objects outside the 10-gauss perimeter from the
centerline of the magnet.
The strong magnetic field surrounding the magnet attracts
objects containing steel, iron, or other ferromagnetic
materials, which includes most ordinary tools, electronic
equipment, compressed gas cylinders, steel chairs, and steel
carts. Unless restrained, such objects can suddenly fly
towards the magnet, causing possible personal injury and
extensive damage to the probe, dewar, and superconducting
