Operator’s Manual 13 - 57
• Keep the magnetizer away from any device that is sensitive to magnetic
fields. Never place or hold the magnetizer within 1 m of the probe.
• The eSpacial Navi system supports only the needle types listed on the
needle list. For details, see “13.4.1 Interface”.
• Keep the eSpacial Navi probe away from the source of disturbance, such
as metal objects and magnetized objects. Do not use or store the eSpacial
Navi probe in the vicinity of strong electric or magnetic fields.
• When used under optimal operating conditions by an experienced medical professional, the
eSpacial Navi system can achieve precision as high as ±2.4 mm.
• Place the magnetizer in the proper position to prevent the magnetizer from falling off or
becoming damaged.
• DO NOT make the magnetizer overheated (more than 50 °C) during cleaning and
disinfections. High temperature may cause the magnetizer to become deformed or damaged.
