1 Safety Information
1.1 MRI Safety Definition for MRI as Defined by International Standards ASTM
F2503-13
MR SAFE
An item that poses no known hazards resulting from exposure to any MR
environment MR SAFE items are composed of materials that are electrically
nonconductive, non-metallic, and nonmagnetic.
MR CONDITIONAL
An item with demonstrated safety in the MR environment within defined
conditions. At a minimum, address the conditions of the static magnetic
field, the switched gradient magnetic field and the radiofrequency fields.
Additional conditions, including specific conditions of the item, may be
required.
Supplementary marking –additional information that, in association with
marking as “MR CONDITIONAL” states via additional language the conditions
in which an item can be used safely within the MR environment.
MR UNSAFE
An item with poses unacceptable risks to the patient, medical staff or other
persons within the MR environment.
1.2 General Safety Information and Intended Use
The metal detector must only be operated by personnel properly trained in MRI safety and identifying
interference problems such as artifacts, streaks and distortions in image data. It is required that as personnel
handling the metal detector are familiar with the safety instructions given in the manual and other
documentation provided to ensure safe operation of the sound system and associated equipment.
1.3 Health Concerns
Warning!
If any of the components become damaged, stop using the headset immediately

1.5 Warnings for MRI
Caution!
Take care that metal detector should be kept at least three meters away from the
magnet since it is MRI unsafe
Caution!
In addition, no persons with ferromagnetic prosthetic devices, such as pacemakers
or joints replacement, should enter the MRI suite at any time. Extreme, high
magnetic fields inside the magnetic room have the potential to dislodge items at
high velocities and can result in serious injury, or death.
Caution!
For questions regarding technical support, call Troyka Med service team or contact
via email at [e-mail].
Caution!
Only system components explicitly designed for use inside the MRI suite should be
placed inside the magnet room. Components not designed for MRI use may present
a projectile hazard and can become airborne, causing serious injury, damage or
death.

3 System Overview and Installation Guide
3.1 System Overview
The MD-100 Hand Held MRI Metal Detector is designed to be used pre-MRI scans and is manufactured and
tested to the highest standards. The metal detector is designed to be used before all MRI scans.
The metal detector - with both audible and silent vibrating alarm options - offers outstanding performance
stability and extreme sensitivity in detecting the smallest objects when used properly. Its state of the art
digital circuitry allows instant operation with no operator adjustment required.

3.2 Components / Function
3-Way Power Switch
Has two On positions and a central Off position. When the Power Switch is pressed forward, the detector
will sound an audible alert upon detection of any metal and the red Light Alert will appear. When the switch
is pressed backward, the detector will vibrate upon detection of any metal and no sound will be heard even
though the red Light Alert will appear. Power is turned off when the switch is in the central position.
Light Alerts
The rear green light illuminates whenever the detector is operating. The red light, forward most of the three
lights, illuminates whenever metal is detected. The center amber light illuminates when battery power
becomes low and the battery should be recharged or replaced.
Audio Alert
The speaker provides a clearly audible sound whenever metal is detected. The Audio Alert sounds only when
the Power Switch is pressed forward.
Vibrating Alert
The vibration mode is activated when the Power Switch is pressed backward. The unit’s handle will vibrate
and the red light will alert the operator whenever metal is detected.
Interference Elimination Button
The detector is factory set for a high level of sensitivity to detect the smallest of items. This high level of
sensitivity may produce alarms when approaching a floor containing rebar. Press and hold this button to
decrease sensitivity to a level that does not respond to the rebar. Release button and detector returns to
normal sensitivity.
Safety Sling
Used to assist the operator in convenient handling of the Super Scanner.

3.4 Service Information
Battery Replacement
Slide back the battery cover (do not attempt to remove it), tilt the detector and battery will slip out. Replace
with fresh battery. Because the battery cover will not slide back if the battery is inserted improperly, never
force the cover. When the metal detector is to be stored more than 30 days, remove the battery.
Internal Sensitivity Adjustment
Some applications may require a sensitivity setting other than the nominal factory setting. This may be
achieved by choosing an appropriate test target and utilizing the Internal Sensitivity Adjustment as follows:
Turn on the metal detector. Roll back the grip cover just below the nameplate. Insert a small screwdriver
into the potentiometer located within the exposed hole. Rotate the potentiometer counterclockwise to
decrease sensitivity, or rotate the potentiometer clockwise to increase sensitivity, until the desired detection
of the test target is achieved. An excessive sensitivity setting may result in unstable operation (chatter) and
excessive detection of surrounding metal. Note: this sensitivity adjustment pot is set to the nominal center
(12:00 o'clock) position at the factory.
CAUTION:
Always verify that the metal detector is set to the desired sensitivity level by testing with appropriate targets
anytime the sensitivity adjustment is changed.
