Technologist Control Unit Operation 

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 levelfor 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.
