Installation
Pacemaker precautions. The instrument has an internal magnet. Keep the instrument a minimum of
5 cm (2 in.) from the user. A magnetic field can:
• Stop the stimulating pulses from the pacemaker that control the rhythm of the heart.
• Cause the pacemaker to supply the pulses irregularly.
• Cause the pacemaker to ignore the rhythm of the heart and supply pulses at a set interval.
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
