DEVICE DESCRIPTION
The MRIaudio Sound System is an MRI conditional audio solution that provides MRI patients with music, direct
communication from the technologist and 29 dB hearing protection.
WARNINGS AND CAUTIONS
Please read this manual and follow its instructions carefully. The words, WARNING, CAUTION and NOTE carry special
meaning and should be carefully reviewed:
WARNING: Indicates risk to the safety of the patient or technologist. Failure to follow warnings may result in injury to the
patient or technologist.
CAUTION: Indicates risk to system equipment. Failure to follow cautions may result in product damage and void warranty.
To avoid potential serious injury to the user and the patient and/or damage to this device, please note the following
warnings:
• Check for any obvious damage prior to installing or using equipment. If damage is detected, refer to the standard
warranty.
• The wishbone, In-Ear Headset is much louder than the Over-Ear Headphones. Volume level should not exceed 40%.
• Test the volume level prior to giving a patient the headphones. Prolonged exposure to loud noises can cause hearing
damage.
• The voltage within the device may have sufcient magnitude to cause electric shock. Therefore, it is dangerous to
make any kind of contact with any part inside the device.
• The foam ear-tips on the In-Ear Headphones must be fully inserted into the ear canal to achieve 29 dB of noise
attenuation, or NRR (Noise Reduction Rating).
• Do not remove the cover on any of the equipment as there are no user serviceable parts inside.

• Do not modify this equipment in any way.
• Never use the system in the presence of ammable or explosive gases.
It is critically important that only MR Safe and MR Conditional components be taken into and installed in the MRI suite.
When installed correctly, the MRIaudio Sound System is MRI-compatible and will produce high-quality audio for patients
undergoing MRI scans.
INDICATIONS FOR USE
The MRIaudio Sound System is intended to provide audio entertainment and facilitate patient communication in MRI
environments up to, and including, 3.0 Tesla. The product is not intended for medical diagnosis or treatment. Technologist
control units are intended to be used outside of the MRI scan room.
WARNING: Portable RF communications equipment including peripherals such as antenna cables and external antennas
should be used no closer than 12 inches (30 cm) to any part of the MRIaudio Sound System or cables. This could result in
a performance degradation of the system.
WARNING: Use of accessories, cables, and other equipment not specied or provided by MRIaudio could result in
increased electromagnetic emissions or decreased electromagnetic immunity of the equipment and result in improper
operation.
WARNING: Use of system equipment adjacent to or stacked with other equipment should be avoided. This could result
in improper operation. If this scenario is necessary, the equipment should be observed to verify the system is operating
normally.
NOTE: The emissions characteristics of this system equipment make it suitable for use in industrial areas and hospitals
(CISPR 11 class A). If used in a residential environment (for which CISPR 11 class B is normally required), this equipment
might not offer adequate protection to radio-frequency communication services. The technologist might need to relocate
or re-orient the equipment.
CLEANING
Device components can be cleaned with a dampened small cloth with rubbing alcohol or hand sanitizer. Do a quick wipe
over the surface of the devices as well as the wires. For the Over-Ear Headphones, clean the ear cups with a sanitizing
wipe. To avoid patient cross contamination, replace the headphone cloth covers after each scan session. For the In-Ear
Headphones, clean the entire plastic wishbone with a sanitizing wipe. Replace the foam ear tips after each scan session.
EMERGENCY PROCEDURE
In the unlikely event that either the MRIaudio Sound System or any component creates smoke, sparks, or if the patient
requires emergency assistance:
• Stop the scan immediately if one is in progress.
• Remove the headphones from the patient.
• Remove the patient from the scan room if medical treatment is needed.
REPORTING INCIDENTS
Contact MRIaudio immediately to report an incident and/or injury to a patient, operator or maintenance employee that
occurred while using the MRIaudio Sound System. Do not operate the equipment until an investigation is conducted.

MR CONDITIONAL
MR SAFE
MR UNSAFE
This device is classied as completely nonmagnetic, non-electrically conductive and non-radio frequency
reactive. This eliminates all primary and potential risks during MRI scanning.
These objects are classied as MRI unsafe. They are signicantly ferromagnetic and pose a clear and direct
threat to persons and equipment within the magnet room.
This system component may contain magnetic, electrically conductive or radio frequency-reactive parts.
These are safe for operation in proximity to the MRI, provided the conditions for safe operation are
dened and observed (both for the MRI scanner and the device itself).

The following steps will walk you through the process for running the 100’
cable from the Digital Amplier to the penetration panel in the computer room.
1.1 Using a mini screwdriver, loosen, then remove the 2-pin terminal clip
attached to the pigtail end of the 100’ cable (Fig. 1). Set the pin aside for now.
NOTE: The terminal pin may arrive already detached.
1.2 Locate the conduit pipe that begins in the control room and ends in the
computer room. Look for both sides of an existing cable as a guide.
In the control room, the conduit is usually located under the main technologist
desk. In the computer room, the conduit is usually located on the ceiling or
high up on the same wall as the penetration panel. In older facilities, it may be
located underneath the oor panels.
1.3 To run the cable through the conduit, there will be two scenarios:
A) If you already have an older audio system in place, there will be an
existing cable inside the conduit. You can utilize the old cable to pull the
new cable through.
B) For a new cable install, you will need to run a sh tape through the
conduit to pull the new cable through (Fig. 2). Starting in the control room,
feed the sh tape through the conduit until it emerges in the computer
room. This will require periodic checking of the conduit in the computer
room.
1.4 Using electrical tape, wrap the pigtail end of the new DB9 cable onto the
end of the sh tape (or the old existing cable). Make sure to wrap it tightly and
thoroughly in order to prevent detachment or snags when pulling the sh tape
back through.
1.5 Once the cable is securely afxed, return to the control room. Begin to pull
the sh tape/old cable through the conduit until the cable emerges in the
control room. Pull out about 5’ to 6’ of cable into the control room for slack.
On rare occasions, you may not be able to get the sh tape past an obstruction
in the conduit, no matter what you attempt. In this scenario, you will have to run
the cable above the ceiling tiles from the control room to the computer room.
This will require a large ladder, zip ties, and the sh tape to help get the cable
past the drywall. Every facility’s architecture is different and this process will
require a bit of trial and error.
