System Notes
Our Genesis ULTRA Music System has a number features that need to be fully
understood to use this system to its full potential
 Music provides comfort to the patient during the procedure.
 Our MagnaLink™ Pneumatic Stethoscope Style Headsets attenuate gradient noise to patient’s
ears by 30dB (NRR) Tested per ANSI standard and comply with the GEHC MR Operators Guide.
 DSP technology provides the highest sound quality available for the patient.
 Active volume compensation (Auto Gain) changes volume automatically to help mask MR gradient
sounds.
 Patient volume and music selection controls with voice feedback for maximum comfort and
versatility.
 Backlit Technologist Control Unit allows operation of the entire system with a touch of the button,
even in low-light environments.
 Built-in intercom allows the Technologist to communicate directly with the patient even while the
scan is in progress.
 Complete AM-FM stereo, CD and iPod interface.
 Built-in interface for AutoVoice and intercom integration all GE MRIs.
 Built-in Patient Ready Signal (PRS) to signal patients’ readiness for the scan to begin.
 Built-in interface for fMRI.
 Built-in interface audio portion of Video.
 100 % Microprocessor controlled which simplifies operation and programming.

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.

1. There are two sizes of
MagnaPlugs available:
 MagnaPlug .75” X .50” for
average size ear canals
 MagnaPlug Mini .75” X .38”
for smaller than average size
ear canals
2. The MagnaLink™ “Yoke” will
provide a small amount of
tension to maintain the
MagnaLink to MagnaPlug to
patient ear canal connection.
3. The MagnaLink couplers
rotate to facilitate alignment
of MagnaPlugs with the
patient’s ear canals.
4. Please identify what size
MagnaPlug is required for the
patient and then insert them
into the MagnaLink couplers.
5. Hold the MagnaLink headset
in your hands. Using your
thumbs and first fingers gently
start rolling, gradually
increasing pressure.
6. Roll until you reach the
smallest diameter possible.
Avoid pinching.

MagnaLink™ Headset & MagnaPlug™ Instructions
10. There is a very good and informative YouTube Video titled “Fitting Foam Earplugs”. Please review
for help with the proper technique for the insertion of foam earplugs into the ear canal.

Caution:
1. Only use the Magnacoustics MagnaLink™ System with your Magnacoustics Music System.
This will ensure your patients hearing protection with all coils in addition to allowing your system to
meet and/or exceed GE Healthcare’s attenuation requirements.
2. Use of any other headset with your Magnacoustics MRI Music System will NOT work and may
cause serious patient safety issues.
3. The Magnacoustics MagnaLink™ System was designed for Magnacoustics MRI Music Systems
Only. Use on other non-Magnacoustics Systems may cause serious patient safety issues.

7. Insert one side of the headset
at a time into the patient’s
ears. (Best done when the
patient is in the supine
position)
8. Hold in place or instruct the
patient to hold for about 15 to
20 seconds so that the
MagnaPlugs can fully re-
expand.
9. After the scan is completed,
discard the MagnaPlugs. Do
not attempt to reuse them, they
are a disposable item. Ear
infections are spread very
easily.
