Genesis ULTRA Installation and Connections continued
29: There are very sensitive pressure switches located in the Transducer if pressure builds up even
due to a temperature differential the switches might activate causing the volume to go up or
down, or music selections to change on there own with no input from the patient. Therefore it is
good practice to let the Controls and Transducer sit for a few hours at Scan Room temperature
then follow the vent procedure below. Vent the Patient Volume Control and Patient Selection
Controls to the atmosphere by pulling the tubing from the nipples on the Transducer one pair at
a time (observing polarity for proper synchronization). This also corrects for vacuum or pressure
built up from shipping.
30: Connect Gradient noise sensing Mic to the BNC connection on the side of Transducer. Place
Mic near the front of the bore. Secure with mounting pad and zip tie.
31: Connect the clear Siamese Headset tubing to the large brass tubes protruding from the top of
Transducer.
32: Connect the Headset to unconnected end of clear Siamese tubing.
CAUTION Ensure that all connections are complete before connecting AC power
33: Connect power cord from Stereo to AC receptacle 120V / 15 Amp minimum.
34: Connect the plug side of “CB8” to AC receptacle 120V / 15 Amp minimum.
35: 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 pull AC Power and contact Magnacoustics Tech Support at 1-
800-637-2282 or E-mail at
for further details.
36: Press the green Power Button on the TCU a self-test should complete and the system should
power up in Tuner mode. (It may be necessary to adjust the FM antenna to get better reception.
Keep in mind that if the MRI is located in the basement or with most of the transmitting Radio
stations separated by the Scan Room, some form of external antenna might be required).
37: After making sure the Stereo is playing ok (with Tuner, Tape 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 Blue MIC button have them speak into the MIC and
ensure you can hear them loud and clear.)
38: In order to set the AUTO GAIN it will be necessary Program the ambient and Full Scan Sound
Pressure Levels into the Microprocessor. Depress the
PROGRAM
button once; depress the
MUSIC VOL-
button
to toggle down till Ambient MIC SET is highlighted. Then depress the
INPUT/ENTER
button once and then again allowing the Auto Gain Mic to capture and record the
(Sound Pressure Level) in the room with the scanner idle. Then depress the
MUSIC VOL-
once
to highlight LOUD MIC SET depress the
INPUT/ENTER
once, set up a Phantom and start the
Scanner for and average scan, then depress the
INPUT/ENTER
one more time to capture and
record the (Sound Pressure Level) of an average Scanner. Then depress the
PROGRAM
once
(which will store the two extremes) and let the Microprocessor calculate when and how much
Auto Gain in necessary.
