Preventive Maintenance
EXTERNAL INTERCONNECT CAUTION: Because we use the Scan Room Shielding as our ground
reference, any auxiliary connections to the stereo that are at a different ground potential may also cause
system damage, interference in the scanner and a 60 cycle hum from the speakers or patient headset. Do
not connect any external Antenna or Audio input to the stereo without the proper isolation.
1. Radio Shack Ground Loop Isolator Catalog # 270-054 with the proper phono to 3.5mm stereo adapter
and Radio Shack Catalog # 274-883 or appropriate adapter must be used.
2. A 75 to 300 ohm adapter in series with the any external antenna source must be used.
POWER CONNECTION CAUTION:
1. Please ensure that all low voltage connections are complete before connecting the AC power cords.
2. Please do not make or break any connections to our equipment while the AC plugs are live / connected
to power or damage will result!!
3. To preserve RF integrity in the scan room we float our ground from the penetration panel.
4. Please ensure that the module and stereo AC plugs are connected to outlets that are at the same
Ground Potential as the Scanner or Damage to our Equipment and or poor SNR performance will
result!!
CD-ROM USE NOTE:
1. CD-ROM media is subject to deterioration, just like any other material. CD-ROMs are made of many
layers, and the materials used in these layers change over time, depending on when they were made
and how they age. Depending on susceptibility, wear, and environment, various layers of a CD-ROM
may undergo oxidation; hydrolysis or mechanical stress, leading to damage that will cause the CD-
ROM to skip in your favorite song or not to play at all.
2. It’s nearly impossible to prevent the accumulation of dust, scratches and scuffs from occurring,
especially with frequent use; the resulting accumulation can mean either a skip in your favorite music
track, or not playing at all. To get the best performance from your CD-ROMs, keep them and the optical
pickup mechanism clean. Whenever possible, discs should be stored in their case. Dirty CD-ROMs can
also transfer dust or debris on the optical pickup mechanism by centrifugal force. CD-ROMs should be
cleaned every week or sooner based on usage and if used in a dusty environment or the system has
trouble reading them clean more often.
a. To clean the CD disk, purchase a Maxell CD-335 Scratch Repair / Cleaner Kit Model: CD-335
available from RadioShack Catalog #: 5501660. These are also available from Amazon.
b. To clean the CD optical pickup mechanism, purchase a Maxell CD-340 CD Lens Cleaner Model:
CD-340 from RadioShack Catalog #: 55016610. These are also available from Amazon.

Troubleshooting Guide
Symptom: Low Volume to Patients Ears
Diagnostic Observation 1: Determine which type of headset is being used.
Cause / Corrective Action 1: The MagnaCoil™ Headset and MagnaLink™ Headset 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. Use of any other headset will cause a drastic reduction of
volume as well as creating a potential health risk to the patient by not providing sufficient hearing
protection. If this does not correct the issue please contact Magnacoustics Customer Support.
Diagnostic Observation 2: Check to be sure the clear siamese tubing has not been extended or kinked.
Cause / Corrective Action 2: Do not add additional tubing, each additional foot reduces the SPL by
approximately 3dB and affects the sound quality. (Follow Step “27” in the Installation and Connections
instructions for proper placement). When positioned in the correct location, extra tubing is not necessary.
If the tubing has become kinked try to un-kink or contact Magnacoustics Customer Support.

MagnaCoil™Headset & MagnaPlug™Instructions
The MagnaCoil™ Headset 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.
MagnaCoil™Headset & MagnaPlug™Instructions
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. Please identify what size
MagnaPlug is required for
the patient then insert them
with a twisting motion into
the Magna MagnaCoil™
Couplers.
3.Hold the MagnaCoil™Coupler
in one hand Using your thumb
and first finger on your other
hand gently start rolling the
MagnaPlug smaller, increasing
the pressure until you reach the
smallest size possible. Avoid
pinching / folding.
4. There are a left and right side
Coupler, insert the
appropriate side with the
MagnaPlug into the patient’s
ear-canal. Hold in place
about 10 ~ seconds for the
foam to expand before
releasing.
5. Then loop the tubing over the
top of the ear. For best
performance please insert the
MagnaPlug into the patient’s
ear-canal as depicted above.
The deeper the plug is inserted
the more attenuation they will
provide.
6. After the scan is completed,
remove the headset by pulling on
the Red Couplers & discard the
MagnaPlugs. Do not attempt to
reuse them, they are a
disposable item. Ear infections
are spread very easily.

Terminology: TCU = Technologist Control Unit
1: To turn Genesis MRI Music ON from TCU push the Green Power button (located on the top right
corner).
2: To adjust Technologist’s Speaker Music Level depress the Green TECH VOL+ and the Red
VOL– (located to the left of the Power button) for UP and Down respectively. The Stereo will show
the level. To Mute the Technologist’s Speakers depress the Violet TECH MUTE button (located
under the Red VOL- button). The “ON” will flash on the mid right side of the display in the MUTE
box.
3: On power up the microprocessor sets VOL, Mic, and AVC level for patients wherever it was left
when the system was turned off. The number equals the percentage of volume and the horizontal
bar gives a quick visual representation.
4: Depressing the Green Mic button (located on bottom left corner) will allow you to override music
and talk to the patients. Level can be adjusted buy depressing Green Mic VOL+, or the Red VOL-,
for UP and Down respectively. A good starting point is 50. When Mic button is depressed you will
see “Mic” on the lower left “MODE” box of the display.
5: When the AVC (intercom integration) input has triggered from depressing the Mic button on your
GE Intercom (providing the intercom integration kit was installed) the Display will show AVC in the
lower left “MODE” box, and the music to the patient will be interrupted. The AVC level and the
console intercom level will control the level to the patients (it’s a good idea adjust the AVC and,
leave the console set the same for a Patient without Headsets.) A good starting point is 50 but no
two MRIs are the same.
6: Depressing the Red PAT OVERRIDE button (located above the Mic button) will toggle thru locking
out the patient from adjusting the VOL, SEL, VOL SEL, or OFF. This will also be displayed on the
lower right “PAT OVR” box.
7: We recommend getting in the habit of depressing the Red PAT MUTE button (located above PAT
OVERRIDE button) after each patient (this way when you are setting up a new patient they will be
able to hear you, if the music is on they probably can’t.)
8: Depressing the Green VOL NORM button (located above VOL OFF button) will raise Volume for
the Patients to 20. This preset is a good starting point and can be adjusted in program mode
described in step 14.
9: Depressing Red MUSIC VOL- button (located above the VOL NORM button) will lower Volume for
the Patients, and depressing the Green MUSIC VOL+ (located above the MUSIC VOL- button)
will raise Volume for the Patients.
10: The Genesis has a feature called AUTO GAIN this provides the ability to automatically adjust
volume level of music to Patients dependent on the amount gradient noise being created by MRI.

11: Depending on how loud the Scan Sequence is the AUTO GAIN can be turned on and off by
depressing the Blue AUTO GAIN button (located under the Red Mic VOL- button). The AUTO GAIN
setting can be seen on the upper left corner of the display in the “GAIN” box (Off, Idle, Low, Med,
and High). When the AUTO GAIN is active you can also see an ^ to the left of the VOL BAR
indicating that it has adjusted the MUSIC LEVEL to the Patient. The percentage can be adjusted to
5%, 10%, 15%, 20%, or 25% per stage in the PROGRAM MODE STEP 14.
12: Depressing the Blue COMP button (located under the Blue AUTO GAIN button) will provide a more
even flow of Music to the Patient, by raising the lows and lowering the highs.
13: All the other buttons control the Stereo.
14: Depressing the Blue “PROGRAM” button (located below the red AVC VOL- button) will put the
system in “Program Mode. Depressing the MUSIC VOL+ and VOL- button toggle up and down
through the Menu respectively. Depressing the Blue / Green INPUT/ENTER button (located bellow
the Blue PROGRAM button) will toggle the options in the menu that is highlighted. Depressing the
PROGRAM button again will memorize any changes you have made and exit the Program Mode.

25: Route cable “CB2” on opposite side of the cold head (if used) to the front of the MRI
utilizing existing conduits.

26: Leave approximately 12” of cable “CB2” protruding from the front center of the MRI
directly above the table docking mechanism for a service loop, or alongside the base of the
gantry. It is important to locate the end of “CB2” as close as possible to the front center of
the bore.
27: For all MRI’s it is very important to locate the Transducer as close as possible to the
front center of the bore. For all GE MRI’s locate the Transducer either side of the
pedestal above the Up / Down height control peddles as pictured below. Connect cable
“CB2” to the Transducer.
28: There are 4 very sensitive pressure actuated switches for the patient controls located in the
Transducer. During shipping sometimes pressure or vacuums can build in the controls
causing erroneous operation of the patient volume and mode selection buttons.
Therefore it is good practice to let the Controls and Transducer become acclimated to the
scan room environment for a few hours or until the temperature stabilizes then;
a. Vent the patient controls to the atmosphere by momentarily removing the white tubing
one pair at a time and reconnecting them to the nipples on the Transducer observing
polarity for proper synchronization.
29: Insure that the Gradient noise sensing Mic is connected to the BNC connection on the side
of Transducer. Place the Mic anywhere in the general area. Secure with the provided
mounting pad and zip tie.
30: Connect the clear Siamese Headset tubing to the brass tubes protruding from the top of
Transducer. Do not add any additional tubing length to this system, doing so will
adversely affect performance and reliability.
31: Connect the Headset to Siamese tubing.
Power Connection Caution:
1. Please ensure that all low voltage connections are complete before connecting the AC
power cords.
2. Please do not make or break any connections to our equipment while the AC plugs are
live / connected to power or damage will result!!
3. To preserve RF integrity in the scan room we float our ground from the penetration panel.
4. Please ensure that the module and stereo AC plugs are connected to outlets that are at
the same Ground Potential as the Scanner or Damage to our Equipment and or poor
SNR performance will result!!

Genesis ULTRA Installation and Connections - continued
32: Connect power cord from Stereo to AC 100-120V / AC receptacle located at operators’
console. GE sites us power from the GOC, Hitachi Sites us 100V system power.
33: Connect the plug side of “CB8” to AC 100-120V / AC receptacle located at operators’
console. GE sites us power from the GOC, Hitachi Sites us 100V system power.
34: Look at the front panel of the Genesis and ensure the all-8 red LED’s are lit under Circuit A
Power and Circuit B Power. If not, unplug the AC power cords and contact Magnacoustics
35: Press the green Power Button on the TCU a self-test will complete and the system should
power up in Tuner mode. (It may be necessary to adjust the FM antenna to get better
reception. Please keep in mind that if the MRI is located in the basement or if most of the
transmitting Radio stations are separated by the Scan Room RF Shielding, some form of
auxiliary or external antenna might be required.
36: After making sure the Stereo is playing ok (with Tuner, iPod or CD selected). Depress the
Green VOL NORM button and go into the Scan Room to ensure there is music playing
from the Headsets. (If you have help depress the Green Mic button speak into the
supplied Mic (make sure the Mic mute switch is off) to ensure intercom operation.
Auto Gain Calibration Procedure
37: In order to calibrate the Microprocessor for AUTO GAIN Function it will be necessary to
program the Ambient and Full Scan SPL levels, the please follow this procedure;
a. Depress the Blue PROG MODE button once.
b. Depress the MUSIC VOL- button to toggle down till 11. Ambient MIC Set is highlighted.
c. Depress the INPUT/ENTER button once and then again allowing the Auto Gain Mic to
capture the SPL in the room with the scanner idle.
d. Depress the MUSIC VOL- once to highlight 12. SCAN MIC Level Set depress the
INPUT/ENTER once.
e. Set up a Phantom and start the Scanner for and average scan (Full Scan Level).
f. Depress the INPUT/ENTER one more time to capture the SPL in the room with the
scanner active.
g. Depress the Blue PROG MODE once (which will store the two extremes) and let the
Microprocessor calculate how much Auto Gain in necessary.
EXTERNAL INTERCONNECT CAUTION: Because we use the Scan Room Shielding as our
ground reference, any auxiliary connections to the stereo that are at a different ground potential
may also cause system damage, interference in the scanner and a 60 cycle hum from the
speakers or patient headset. Do not connect any external Antenna or Audio input to the stereo
without the proper isolation.
a. Radio Shack Ground Loop Isolator Catalog #: 270-054 with the proper phono to 3.5mm
stereo adapter and Radio Shack Catalog # 274-883 or appropriate adapter must be used.
b. A 75 to 300 ohm adapter in series with the any external antenna source must be used with
one wire only.
