4.5 Special safety instructions when working in the

vicinity of powerful magnetic fields

RISK TO HEART PACE-MAKER WEARERS 4

The permanent magnets of the Y-axis have an extremely powerful magnetic field. Personnel wear-

ing heart pace-makers are NOT permitted to stand in the vicinity of permanent magnets (see

item 1 and 2 in Fig. 4.5 - 1). 4

CAUTION POWERFUL MAGNETIC FIELD 4

Æ Do not wear watches in the vicinity of permanent magnets since they can be damaged.
