PREPARATION FOR USE
1.0 PREPARATION FOR USE
1.1 Introduction
This section contains information relative to the initial inspection and pre-
operational checkout of the MRidium 3850 Infusion Pump/Controller, the 3851
SideCar Secondary Pump and 3855 Remote Display/Charger. These procedures
include a mechanical inspection, electrical inspection, pre-operational battery
charge and a performance check to ensure that the instruments operate
properly and have not been damaged during shipment or storage. The MRidium
3850's operating features are identified in the MRidium 3850 Operation Manual
(IRadimed PN 1124).
1.2 Pre-Operational Mechanical Inspection
The MRidium 3850 and it’s accessories have undergone thorough production
control and quality assurance testing prior to shipment from Iradimed. The
shipping container has been designed to protect the instruments against damage
under normal shipping conditions; nevertheless, internal physical and/or
electronic component damage could have occurred without leaving a visible
signature. Therefore, it is recommended that the following inspection procedure
be performed upon receipt of the instruments at the user's facility.
1. Carefully remove the MRidium 3850, 3851 or 3855 from their shipping
containers. (It is recommended the shipping material be saved in the event
an instrument has been damaged and must be returned to the factory for
service or repair).
2. Inspect the exterior cases, front and rear, for holes, cracks, scratches,
broken or damaged controls, missing components and/or screws.
3. Inspect the display window covering and overlay for scratches or cracks
(3850 or 3855).
4. Ensure the pumping chamber access door fits flush with the case at the top,
bottom, and sides (3850 or 3851).
5. Check the door handle/cam lock for ease of operation and flush fit with
door when latched (3850 or 3851).
6. Inspect the pumping mechanism seal for damage and to ensure they are
properly attached to the front case (3850 or 3851).
7. Inspect the Bubble detector and Flo-Stop recess for damage or
obstructions (3850 or 3851).
8. Install an approved Iradimed administration set to ensure the Flo-Stop
assembly seats correctly and the door closes and latches properly (3850 or
3851).
9. Actuate each of the keypad controls on the front panel and ensure proper
operation (see Section 1 of 1124 Operation Manual for location of controls)
(3850 or 3855).
10. Exercise the pole clamp mechanism to ensure freedom of movement
(3850 only).
11. Inspect the power cord for damage, bent prongs or deformed connector
(3850 or 3855).

1-2
12. Inspect AC Power/Charger Module and Power/Charger cable for physical
damage and/or missing parts (3850 only).
1.3 Operational Performance Check
Prior to the first operational use and following any routine maintenance or
servicing of the MRidium 3850 and it’s accessories, it is strongly recommended
that an operational performance check be performed. The operational
performance check consists of two phases; a Pre-operational Electrical
Inspection to check the electrical integrity of the instrument for compliance
with regulatory agency requirements and an Operational Performance Test to
verify proper pump operation.
1.3.1 Pre-operational Check Battery Charge
Connect External DC Power/Charger (1120) power cord (1121) to AC
Outlet, connect DC Charger cable from External DC Power/Charger
(1120) to 3850 pump DC input insuring connectors at both ends are
screwed in tightly and allow the battery to charge for 6 hours.
1.3.2 Pre-operational Electrical Inspection
The pre-operational electrical inspection includes an electrical leakage
test and a ground continuity check.
1.3.2.1 Electrical Leakage Test
Connect power cord (1121) to safety analyzer. Connect
ground cable from safety analyzer to the front chassis door
latch clamp. Perform an electrical leakage current
measurement in compliance with Underwriters Laboratories
(UL) 2601 for Patient Care Equipment and / or IEC-60601-1.
Leakage currents are to be less than 300 microamperes.
1.3.2.2 Electrical Ground Test
Connect External DC Power/Charger (1120) power cord
(1121) to 25 Amp Ground tester, connect DC Charger cable
from External DC Power/Charger (1120) to 3850 pump DC
input insuring connectors at both ends are screwed in tightly.
Open pump door and connect alligator clip of chassis Ground
wire from Ground tester to front chassis door latch pin and
verify less than 0.1 ohms ground resistance and no fail test
status.
NOTE
In the event a MRidium 3850, 3851 or 3855 shows evidence of shipping damage,
notify the carrier's agent immediately. Do not return a damaged instrument to the
factory before the carrier’s agent has authorized repairs. Contact IRadimed for
authorization to return the instrument for repair regardless of liability for repair
costs.
CAUTION
Some of these tests are inherently hazardous. Safeguards for personnel and
property should be employed when conducting such tests. Tests should only be
performed by qualified personnel.

Note: In software version 582 or later, the COMM channel number can be
seen adjacent to the radio antenna icon on the display.
Troubleshooting aids for radio communication in very RF-tight MRI
Magnet Rooms:
1) Channel selection - each of the 6 channels actually modify several commu-
nications parameters which provide a very wide range of RF link diversity.
Please try different channels to find the best link.
2) Location - the 3855 Remote unit must be located close to the wall/window
into the MR scanner room. It is recommended to be less than 3 feet away
from the window. Do not allow people to get between the remote and pump,
humans absorb large amounts of the 2.4 GHz frequency power of the link.
3) Adjust Radio Transmission power - IN the Service Mode, the radio power
can be adjusted from medium power (+18 dBm is the standard factory set-
ting) to high power (+24 dBm).
4) External Antenna - You can add an external antenna with longer cable
which can be fixed directly on the viewing window. This can increase commu-
nication reliability in most all cases.
WARNING: Never Set two Pumps or Remotes on the same Comm Channel.
Always confirm the remote display is communicating with the selected before use.

SERVICE MODE DESCRIPTION
2.0 SERVICE MODE DESCRIPTION
The MRidium 3850 is configured with a Service Mode that allows technicians to
access the software diagnostic subsystem. Once the Service Mode is enabled,
the technician can use the diagnostic test sequences to verify operation of the
operator interface features, to operate the pumping mechanisms independent
of the alarm/malfunction interrupts, to check Analog to Digital voltages and to
access the history log. Additionally, the Service Mode is used to test the serial
port, configure the instrument's radio communication interface and select one
of the six available languages for the user interface presentations (when
available).
Put Pump into Service Mode by Press overlay KeyPad On (I) button and the
holding the overlay KeyPad Cancel key depressed until the Service Mode is
displayed. Once enabled, Maintenance Mode operation is strictly software
dependent.
The Channel B Start/Stop key changes the pump from SERVICE MODE A
(main 3850 pump) to SERVICE MODE B (3851 SideCar pump).
2.1 Service Mode Display
Figure 2-1.
The initial Service Mode A screen (see Figure 2-1) displays current time, P1
pressure sensor located directly above the pump mechanism for inlet
pressure/occlusion sensing for pump channel A, and P2 located below the
pump mechanism for patient side fluid pressure sensing of pump channel A, if

2-2
the side-car is installed P3 pressure sensor located directly above the pump
mechanism for inlet pressure/occlusion sensing for pump channel B, and P4
located below the pump mechanism for patient side fluid pressure sensing of
pump channel B; Sensor A to D count is displayed on the left with pressure in
psi displayed on the right of each location. These are non-selectable
information displays.
Selections from the Service Mode screen are Rate, Calibrate Pump, Manual
Pump Run, and Move to Index. The initial selection is Rate, from this selection
the Up and Down keys are used to change the Rate, Enter key is used to set
the selected Rate, and Start/Stop Channel A key. “Calibrate Pump” is used for
initial pump calibration and requires a Sartorius GD603 scale connected to the
pumps I/O port, and is used to find the pumps index offset point (typically for
factory use only). “Manual Pump Run” when selected and the enter key is
pressed commands the pump to run at a constant speed and is used for motor
tuning. “Move to index” when selected and the Enter key is pressed,
commands the pump to move to index (beginning of pump cycle).
The top row of numerics at the bottom of the screen are defined as follows.
the first position displays motor speed in RPMs, the second position is for
display of the scale weight value when connected to the Sartorius GD603
scale, and the third position is for display of the various completion and error
codes when using the Sartorius GD603 scale for calibration.
The fourth position shows the motor counter timer, which decrements from
1000 to 0 as the motor rotates. When the motor is stopped, the counter timer
is set to 240 (as shown). Whenever the motor is started, or the flow rate is
changed, the counter timer is rest to 1000.
The bottom row of alpha-numerics are defined as follows:
??? - On initial enter to the to the Service Mode screen this area will display
???, once the pump has been commanded to move it will display the current
position of the encoder wheel.
B- “B” equals bubble detected or air in line at bubble detector, “b” equals no
bubble detected.
P- “P” equals Line power is detected, “p” equals no line power detected.
7- This numeric is currently for factory use only.
1113 - This numeric is a display of the regulated 11V power supply, (1113 =
11.13V).

The Delay setting should be recorded for future reference should a repair action
cause loss of this Delay setting. This Delay setting is found during factory
calibration with the pump connected to a high accuracy calibrated scale (Sartorius
GD603) while the delivery profile at 1 ml/Hr is studied by internal calibration
software. Anytime the mechanical alignment of the encoder wheel relative to the
pumping finger position is changed or suspect ( pump block or motor replaced ),
this calibration process must be performed.
