Summary of Safety Precautions

Safety Tips and Guidelines

Before operating the 2040 Patient Transport Frame, it is important to read and understand all information in this manual.
Carefully read and strictly follow the safety guidelines listed on this page. To ensure safe operation of the transport
frame, methods and procedures must be established for educating and training hospital staff on the intrinsic risks
associated with the usage of motorized electric units

WARNINGS

• The 2040 Patient Transport Frame is equipped with a hospital grade plug for protection against shock hazard. It
must be plugged directly into a properly grounded three-prong receptacle. Grounding reliability can be achieved
only when a hospital grade receptacle is used.

• Serious injury can result if caution is not used when operating the unit. Operate the unit only when all persons are
clear of the electrical and mechanical systems.

• To help reduce the number and severity of falls by patients, always leave the bed in the lowest position when the
patient is unattended.

• When raising the siderails, listen for the “click” that indicates the siderail has locked in the up position. Pull firmly
on the siderail to ensure it is locked into position. Siderails are not intended to be a patient restraint device. It is
the responsibility of attending medical personnel to determine the degree of restraint and the siderail positioning
necessary to ensure a patient will remain safely in bed.

• Always apply the caster brakes when a patient is getting on or off the bed. Always keep the caster brakes applied
when a patient is on the bed (except during transport). Injury could result if the bed moves while a patient is getting
in or out of bed.

• Ensure the brakes are completely released prior to attempting to move the unit. Attempting to move the unit with
the brakes actuated could result in injury to the user and/or patient.

• Put the drive wheel in the neutral position and release the brakes before pushing the unit manually. Do not attempt
to push the unit manually with the drive wheel engaged. The unit will be difficult to push and injury could result.

• The CPR emergency release requires assistance to lower the Back if the angle of the Back is above 80°. Attempting
to lower the Back in this position without assistance may result in injury to the operator.

• The power save mode is activated after one hour on battery power with no motion release switch activation.
Functions, including Bed Exit scale and motion, will cease to operate when the unit enters the power save mode.
Injury to the patient could occur if proper patient monitoring protocol is not observed.

• The Bed Exit System is intended only to aid in the detection of a patient exiting the unit. It is not intended to replace
patient monitoring protocol. The bed exit system signals when a patient is about to exit. Adding or subtracting
objects from the frame after arming the bed exit system may cause a reduction in the sensitivity of the bed exit
system.

• To avoid pinching your fingers, place the I.V. pole in the upright position before using the drive handle.

• Always unplug the power cord and push the battery power on/off switch to the “Off” position before service or
cleaning. When working under the frame, always place blocks under the litter frame to prevent injuries in case the
Bed Down switch is accidently activated.

• Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State
of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.

• The 2040 Patient Transport Frame is intended for use by trained hospital personnel only.

Service only by qualified personnel. Refer to maintenance manual.

• Do not modify the 2040 Patient Transport Frame. Modifying the unit can cause unpredictable operation resulting
in injury to the patient or operator. Modifying the unit will also void its warranty.

• When using any mattress and/or mattress overlay that increases the overall height greater than 6” extra caution
and/or operator supervision is required to help reduce the likelihood of a patient fall occurring.

Summary of Safety Precautions

Safety Tips and Guidelines (Continued)

To avoid possible injury and to assure proper operation when using a powered mattress replacement system such as
XPRT:

• Confirm proper scale system operation following mattress installation. For best results, secure the therapy mattress
power cord to prevent damage to the cord or interference with the bed frame and the scale system.

• Do not zero bed scales or weigh patient with Percussion, Vibration, Rotation or Turn-Assist active. Patient motion
and position resulting from the dynamic therapy mattress may adversely affect scale system performance.

• Do not initialize (“Arm”) bed exit with Percussion, Vibration, Rotation or Turn-Assist active. The patient motion and
position resulting from the dynamic therapy mattress may adversely affect bed exit system performance.

• When using an XPRT Therapy Mattress extra caution and/or operator supervision is required to help reduce the
likelihood of a patient fall occurring.

CAUTIONS

• Use caution while maneuvering the unit with the drive wheel activated. Always ensure there are no obstacles
near the unit while the drive wheel is activated. Injury to the patient, user, bystanders or damage to the frame or
surrounding equipment could occur if the unit collides with an obstacle.

• Use caution when transporting the unit down halls, through doors, in and out of elevators, etc. Damage to the
siderails or other parts of the unit could occur if the unit comes in contact with walls or door frames.

• If unanticipated motion occurs, unplug the power cord from the wall socket, push the battery power on/off switch
to the “Off” position (the LED will not be illuminated) and actuate the drive wheel pedal to the neutral position.

• The siderails are not intended to be used as a pushing device. Damage to the siderails could occur.

• The use of a mattress overlay may reduce the effectiveness of the siderail.

• When attaching equipment to the frame, ensure it will not impede normal operation. I.E.: Hooks on hanging
equipment must not actuate control buttons, equipment must not hide the nurse call button, etc.

• Use caution when lowering the bed with items attached to the optional accessory rail. If caution is not used, items
may contact the floor resulting in damage to the items and/or injury to the patient or user.

• The lockout buttons on the foot board lock the Fowler, Gatch and Bed Up/Down functions and prevent motion of
the bed. It is the responsibility of attending medical personnel to determine whether these functions should be
locked and to use the buttons accordingly.

• Scale function may be affected by siderail/caster interference. With the litter fully lowered or lowered in Reverse
Trendelenburg, the siderails tucked under the litter in the storage position and the casters turned, there is the
potential for interference between the siderail and the caster. Raise the siderails when lowering the litter to the full
down position to prevent the interference from causing the bed’s scale system to weigh inaccurately.

• If large fluid spills occur in the area of the circuit boards or motors, immediately unplug the power cord from the
wall socket and push the battery power on/off switch to the “Off” position. Remove the patient from the unit and
clean up the fluid. Have maintenance completely check the unit. Fluids can short out controls and may cause
the unit to operate erratically or make some functions completely inoperable. Component failure caused by fluids
could even cause the unit to operate unpredictably and could cause injury to the patient. Do not put the unit back
into service until it is completely dry and has been thoroughly tested for safe operation.

• Preventative maintenance should be performed at a minimum of annually to ensure all features are functioning as
designed. Close attention should be given to safety features including, but not limited to:

• Safety side latching mechanisms,

• Caster braking systems,

• Leakage current 300 microamps max.

• No controls or cabling entangLED in frame mechanisms.

• Frayed electrical cords and components.

• All controls return to off or neutral position when released

• The battery tray assembly weighs 50 pounds. Take care when removing the two hexagonal head screws securing
it to the base frame or personal injury could result.

• The 2040 Patient Transport Frame is not intended for pediatric use or for patients under 50 pounds.

Summary of Safety Precautions

Safety Tips and Guidelines (Continued)

• Because individual beds may have different options, foot boards should not be moved from one bed to another.
Interchanging foot boards between beds could result in unpredictable bed operation.

• The weight of the I.V. bags should not exceed 40 pounds.

• Do not add or remove weight when the bed exit system is armed.

• The cleanliness and integrity of both ground chains must be maintained to minimize static build up and
discharge.

• I.V. Poles should not be used as a bed push/pull device.

The following Caution statements apply to the optional 110V outlet:

• Maximum total load 5A receptacle rating: 125 VAC, 5A, 60 Hz.

• The total system chassis risk current should not exceed 300 uA.

• Grounding continuity should be checked periodically.

• Do not use for life-sustaining equipment.

• Use only hospital-grade equipment with electrical outlet.

• Unplug free-standing equipment before transporting the bed.

Cleaning

Hand wash all surfaces of the bed with warm water and mild detergent. Dry thoroughly. Do not steam clean or hose off
the bed. Using these methods of cleaning is not recommended and may void this product’s warranty. Do not immerse
any part of the bed. Some of the internal parts of the bed are electric and may be damaged by exposure to water.

Suggested cleaners for bed surfaces:

• Quaternary Cleaners (active ingredient - ammonium chloride).

• Phenolic Cleaners (active ingredient - o-phenylphenol).

• Chlorinated Bleach Solution (5.25% - less than 1 part bleach to 100 parts water).

Avoid oversaturation and ensure the product does not stay wet longer than the chemical manufacturer’s guidelines for
proper disinfecting.

CAUTION

SOME CLEANING PRODUCTS ARE CORROSIVE IN NATURE AND MAY CAUSE DAMAGE TO THE PRODUCT IF
USED IMPROPERLY. If the products suggested above are used to clean Stryker patient care equipment, measures

must be taken to insure the bed is wiped with a damp cloth soaked in clean water and thoroughly dried following
cleaning. Failure to properly rinse and dry the bed will leave a corrosive residue on the surface of the bed, possibly
causing premature corrosion of critical components. Failure to follow the above directions when using these types of
cleaners may void this product’s warranty.

For mattress cleaning instructions, please see the tag on the mattress, or contact the mattress manufacturer.

Clean Velcro® after each use. Saturate Velcro® with disinfectant and allow disinfectant to evaporate. (Appropriate

iBED Awareness System Error Codes

Error Handling

• The error handling system provides a mechanism for capturing errors known to the product and providing feedback
to the operator through logged errors or message errors.

• All Logged errors generate a generic blinking error message which will be displayed on the status screen in the
lower area: “Error XXX Call Service”, where XXX is the error code.

• Errors will only be logged if the error log does not already contain the error.

• In the event multiple errors are displayed on the status screen, the error code is used to identify the priority. The
lowest code has the highest priority.

• All logged errors and message errors are persistent until the power is cycled, or the condition is fixed.

• The details for each logged error and error message are detailed in the table below.

Electrical System Information

Inverter Protection Features

The inverter has several features to prevent internal damage:

1. Low Battery Voltage - If the battery voltage at the inverter drops below the low voltage cut-off, the inverter will

shut off.

2. Over-Temperature - If the inverter gets too hot, it will shut off. The over heating may be caused by high ambient

temperature, blocked air flow or an overload condition. When the inverter reaches an acceptable temperature, it

will restart.

3. Over-Power - The inverter will source up to its maximum power rating. If the load requires more, the output voltage

will shut down. Turning the power switch off and on will reset the inverter. Plugging the bed power cord into the

wall socket to charge the battery will reset the inverter.

WARNING

The inverter generates 115 VAC, the same as a wall receptacle. To prevent injury, do not put anything into the electrical
outlets other than an appliance power cord. Keep the outlets covered when not in use. Do not submerge the unit or
subject into moisture.

Static Discharge Precautions

The electronic circuits in the 2040 are completely protected from static electricity damage only while the bed is

assembled. It is extremely important that all service personnel always use adequate static protection when servicing

the electronic systems of the Secure II. Whenever you are touching wires, you should be using static protection.

Static Protection Equipment

The necessary equipment for proper static protection is:

• 1 static wrist strap; 3M part number 2214 or equivalent,

• 1 grounding plug; 3M part number 61038 or equivalent,

• 1 test lead with a banana plug on one end and an alligator clip on the other; Smith part number N132B699 or

equivalent

CAUTION

All electronic service parts will be shipped in static shielding bags. Do not open the bags until you have completed
steps 2 and 3 of the following procedure. Do not place unprotected circuit boards on the floor. All circuit boards to be
returned to Stryker Medical should be shipped in the static shielding bags the new boards were shipped in.

Static Protection Procedure

1. Unplug the power cord from the wall receptacle.

2. Insert the grounding plug into a properly grounded hospital grade wall receptacle. Plug the banana plug of the
test lead into the receptacle on the grounding plug. Connect the alligator clip on the other end of the test lead to
a ground point on the bed.

3. Place the static control wrist strap on your wrist. Connect the alligator clip at the other end of the wrist strap cord
to a ground point on the bed.

Scale System Diagnostics and Calibration (Continued)

Displaying Individual Load Cell Outputs (Continued):

4. Press and release the position button that corresponds with the load cell to be checked. The LCD should display
“X/X=NNN.N”. “X/X” represents the initials of the selected corner, i.e.: H/R will be displayed for the patient’s head
end, right side. “NNN.N” represents the resistance of the load cell.

5. Repeat step four for each corner. Head end weight readings will normally be lower than foot end weights. Weight
readings should be constant. A drifting 000.0 or 999.9 weight, or a reading that does not change when weight is
applied to that corner of the bed indicates a problem with the selected load cell assembly or load cell cable.

Verifying Scale Accuracy:

1. Zero the empty bed. Place a known weight on the center of the bed; the heavier the better and no less than
100 pounds. The displayed weight should be within ±1% of the actual weight.

2. If the displayed weight is not accurate, remove the weight from the bed and proceed to the Scale Calibration section.

Scale Calibration:

Note

It requires two people to enable the calibration mode for the scale system. Raise the siderails when calibrating the scale
to avoid getting inaccurate scale readings due to possible interference between the siderails and the casters.

Calibrate the scale system with a known 50 pounds weight. If exactly 50 pounds is not available, the factory default for
calibration will have to be changed as described in step 6.

1. To enter the calibration mode, unplug the bed’s power cord from the wall socket.

2. Press and hold down the LBS/KGS button.

3. While still holding the LBS/KGS button, plug the bed’s power cord into the wall socket.

now active.

5. Press and hold the Enter button (LBS/KGS). Zero the bed, following the displayed instructions. When the bed is
zeroed, the LCD should display “REF X 100 =<0> 5000”. This is the factory default for 50 pounds. If 50 pounds will
be used to calibrate the scale, proceed to step 7.

6. If exactly 50 pounds is not available, change the display to match the weight you are using. Pressing the Change
Equip. button will move the cursor position to the right. Pressing the up arrow (Zero) button will increase the
numbers. Pressing the down arrow (Scale On/Off) button will decrease the numbers. Scroll through the numbers
until they match the weight you will use for calibration.
