MagnaLink™ Headset & MagnaPlug™ Instructions

  The MagnaLink™ System provides the patient with 30dB of attenuation (NRR) tested per ANSI 

standard and complies with GE Healthcare’s MR Safety Guide Operator Manual, Revision 7 

requirements. 

  Because your MRI can produce sound pressure levels that may cause hearing damage, GE 

Healthcare requires that the Technologist ensure a proper fit of all hearing protection devices. 

  Please refer to the detailed instructions below.  This procedure will take less than 1 minute to 

accomplish, assuming the headsets and consumables are readily available and in close proximity 

to the gantry.
