Introduction

SAFETY TIPS AND GUIDELINES

Before operating the Secure II Bed, it is important to read and understand all information in this manual. Care­fully read and strictly follow the safety guidelines listed on this page.

It is important that all users have been trained and educated on the inherent hazards associated with the
usage of electric beds.

WARNING

 The Secure II Bed is not intended for use with patients less than two years of age.
 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.

 Leave the siderails fully up and locked 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 the attending medical
personnel to determine the degree of restraint necessary to ensure a patient will remain safely in bed.

 Always apply the caster brakes when a patient is on the bed (except during transport). Serious injury

could result if the bed moves while a patient is getting in or out of bed. After the brake pedal is applied,
push on the bed to ensure the brakes are locked.

 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.

 Do not attempt to move the foot end of the bed laterally when the steer pedal is activated. When the steer

pedal is activated, the steer caster at the foot end of the bed cannot swivel. Attempting to move the bed
laterally when the steer pedal is activated may cause injury to the user.

 When attaching equipment to the frame, ensure it will not impede normal frame operation. For example:

hooks on hanging equipment must not actuate control buttons, equipment must not hide the nurse call
button, etc.

 The Chaperone 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 zeroing the weigh system may cause
a reduction in the sensitivity of the bed exit system.

 When large spills occur in the area of the circuit boards, 110 volt cables and motors, immediately unplug

the bed power cord from the wall socket. Remove the patient from the bed and clean up the fluid. Have
maintenance completely check the bed. Fluids can affect the operational capabilities of any electrical
product. DO NOT put the bed back into service until it is completely dry and has been thoroughly tested
for safe operation.

 Do not steam clean or hose off the bed. Do not immerse any part of the bed. The internal electric parts

may be damaged by exposure to water. Hand wash all surfaces of the bed with warm water and mild
detergent. Dry thoroughly. Quaternary Germicidal Disinfectants, used as directed, and/or Chlorine
Bleach products, typically 5.25% Sodium Hypochlorite in dilutions ranging between 1 part bleach to 100
parts water, and 2 parts bleach to 100 parts water are not considered mild detergents. THESE PROD-
UCTS ARE CORROSIVE IN NA TURE AND MAY CAUSE DAMAGE TO YOUR BED IF USED IMPROP­ERLY. If these types of products are used to clean Stryker patient care equipment, measures must be
taken to insure the beds are wiped with clean water and thoroughly dried following cleaning. Failure to
properly rinse and dry the beds 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.
Clean Velcro AFTER EACH USE. Saturate Velcro with disinfectant and allow disinfectant to evaporate.
(Appropriate disinfectant for nylon Velcro should be determined by the hospital.)

Introduction

SAFETY TIPS AND GUIDELINES (CONTINUED)

WARNING

 Preventative maintenance should be performed at a minimum of biannually to ensure all bed features

are functioning properly. Close attention should be given to safety features including, but not limited to:
safety side latching mechanisms, frayed electrical cords and components, all electrical controls return
to off or neutral position when released, caster braking systems, no controls or cabling entangled in bed
mechanisms, leakage current 100 microamps maximum, scale and bed exit systems calibrated properly .

 Always unplug the bed power cord from the wall socket and push the battery power on/off switch to the

“OFF” position before servicing or cleaning the bed. When working under the bed with the bed in the high
position, always place blocks under the litter frame and apply the brakes to prevent injury in case the Bed
Down switch is accidently pressed.

SAFETY TIPS AND GUIDELINES (ZOOM OPTION)

WARNING

 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 or bystanders or dam­age to the frame or surrounding equipment could occur if the unit collides with an obstacle.

 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.

 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.

 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 power save mode is activated after one hour on battery power with no motion release switch activa-

tion. 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.

 Always unplug the power cord and push the battery power on/off switch to the “OFF” position before ser-

vice or cleaning. When working under the frame, always place blocks under the litter frame to prevent
injury in case the Bed Down switch is accidently activated.

 The battery tray assembly weighs 50 pounds. T ake care when removing the two hex head screws secur-

ing it to the base frame or personal injury could result.

 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.

Set–Up Procedures

SET–UP PROCEDURES

It is important that the Secure II Bed is working properly before it is put into service. The following list will
help ensure that each part of the bed is tested.

 Plug the bed into a properly grounded, hospital grade wall receptacle and ensure the ”Power” LED light

at the foot end of the bed comes on.

WARNING

The Secure II 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.

 Plug the optional interface cable into the 37 pin connector under the litter frame at the head end of the

bed, and into the ”Patient Station”, ”Head Wall”, ”Docker Station”, or equivalent (whichever applies). Test
the interface cable to verify it is functioning properly.

WARNING

Use only a Stryker supplied interface cable. Use of any other cable may cause the bed to function improperly
which may result in patient or user injury.

 Ensure the siderails raise, lower and store smoothly and lock in the up position and in the intermediate

position when lowered (page 18).

 Ensure that all four casters lock when the brake pedal is engaged (page 14).
 Raise the Back up to approximately 60. Squeeze the CPR release handle and ensure the Back and

Knee will drop with minimal effort.

NOTE

Ensure that the ”Brake Not Set” LEDs located on the outside of the head end siderails and on the foot board
control panel come on when the brakes are disengaged.

 Run through each function on the foot board control panel to ensure that each function is working properly

(page 21–26).

 Run through each function on both head end siderails to ensure that each is working properly (page

18–20).

 Activate the motion stop system to ensure it is functioning properly: press and hold down the BED DOWN

key. As the bed lowers, lift up on the motion interrupt pan (reference drawing on page 13) and ensure
the downward motion stops. Release the pan and allow the downward motion to continue.

NOTE

The bed’s upward motion or other functions are not disrupted by the motion stop system.

Set–Up Procedures

SET–UP PROCEDURES (ZOOMt OPTION)

If your bed is equipped with the Zoom drive wheel option, run through the set–up procedures on page 10
and continue with the procedures listed below.

 Plug the power cord into a properly grounded, hospital grade wall receptacle. The 12 volt batteries that

provide power to the drive wheel and back–up power to the unit functions will charge whenever the power
cord is plugged into the wall socket. The batteries require approximately 10 hours of charging time before
the bed is put into service.

 Unplug the power cord from the wall socket. Push the battery power switch located on the lower left cor-

ner of the head end to the “ON” position. Again, verify each function on the foot board and siderails is
operating properly.

 With the battery power switch in the “ON” position and the brakes engaged, ensure the “Release Brakes”

LED on the head end control panel is illuminated.

 With the battery power switch in the “ON” position and the drive wheel in the neutral position (not touching

the floor), ensure the “Engage Drive Wheel” LED on the head end control panel is illuminated.

 Run through the operation of the drive wheel (see page 30 & 31) to ensure it is operating properly.

If any problems are found during bed set–up, contact Stryker Customer Service at 800–327–0770.

Damaged Merchandise

ICC Regulations require that claims for damaged merchandise must be made with the carrier within fifteen
(15) days of receipt of merchandise. DO NOT ACCEPT DAMAGED SHIPMENTS UNLESS SUCH DAMAGE
IS NOTED ON THE DELIVERY RECEIPT AT THE TIME OF RECEIPT . Stryker Customer Service must be
notified immediately. Stryker will aid the customer in filing a freight claim with the appropriate carrier for dam­ages incurred. Claim will be limited in amount to the actual replacement cost. In the event that this information
is not received by Stryker within the fifteen (15) day period following the delivery of the merchandise, or the
damage was not noted on the delivery receipt at the time of receipt, the customer will be responsible for pay­ment of the original invoice in full.

Claims for any short shipment must be made within thirty (30) days of invoice.

Base Operation Guide

BRAKE PEDAL OPERATION

WARNING

Always apply the caster brakes when a patient is getting on or off the bed. Push on the bed to ensure the
brakes are securely locked. Always engage the brakes unless the bed is being moved. Injury could result
if the bed moves while a patient is getting on or off the bed.

To activate the brakes, push down once on one of the
pedals located at the midpoint of the bed on both sides
(identified by the label at right). The pedal will remain
in the lowered position, indicating the brakes are en­gaged. To disengage the brakes, push down once and
the pedal will return to the upper position.

NOTE

There are LED lights on the outside of the head end siderails and on the foot end control panel that will blink
when the brakes are not engaged only if the bed is plugged into a wall socket (see pages 20 & 22). The brakes
will still operate properly when the bed is not plugged in.

STEER PEDAL OPERATION (BEDS WITHOUT THE ZOOMt DRIVE WHEEL OPTION)

When the bed is moved, the steer caster helps guide the bed along a straight line and helps the bed pivot
around corners.

To activate the steer caster, move the pedal located
at the head end of the bed to your left as shown on
the label.

NOTE

For proper ”tracking” of the steer caster, push the bed approximately 10 feet to allow the wheels to face the
direction of travel before engaging the steer pedal. If this is not done, proper ”tracking” will not occur and the
bed will be difficult to steer.

WARNING

Do not attempt to move the foot end of the bed laterally when the steer pedal is activated. When the steer
pedal is activated, the steer caster at the foot end of the bed cannot swivel. Attempting to move the bed later­ally when the steer pedal is activated may cause injury to the user.

Litter Operation Guide

CPR EMERGENCY RELEASE

When quick access to the patient is needed, and the Fowler is raised, squeeze one of the two red release
handles (see illustration, page 13) and the Fowler can be quickly guided down to a flat position.

NOTE

The handle can be released at any time to stop the Fowler from lowering.

A

FOOT PROP USAGE

To prop the foot end of the Knee Gatch up, grasp
the handle (A) at the end of the Knee Gatch and
lift upward, allowing the foot prop (B) to engage at
the desired height. To release the prop, lift up on
the handle (A), swing the prop (B) toward the head
end of the bed to disengage the hinge and lower
the foot end.

WARNING

To avoid injury while cleaning or servicing under
the foot section, secure the foot section with string
or bungee cords or hold it up out of the way.

B

FOOT END

FRACTURE FRAME USAGE

A standard fracture frame can be mounted on the bed using the I.V. sockets located on all four corners of
the bed. I.V . poles can be used in conjunction with a fracture frame if I.V. pole adaptor sockets are purchased.

WARNING

Use only retractable traction or fracture frames. Failure to use a retractable frame may result in injury to the
patient and/or damage to the equipment.

FOLEY BAG HOOKS USAGE

The standard Foley bag hooks are found at two locations on both sides of the frame: under the frame below
the seat section and at the extreme foot end of the frame. The optional isolated Foley bag hooks are located
at the foot end of the bed on top of the lift header. The patient weight reading on the scale system will not
be affected when the optional isolated Foley bag hooks are used.

PATIENT RESTRAINT STRAP LOCATIONS

The bed has 12 locations for installing patient restraint straps on the litter top, 6 on each side of the bed.

WARNING

Improperly adjusted restraint straps can cause serious injury to a patient. The clinician must use her/his
judgement to determine proper use of restraint straps and restraint strap locations.

Clean Velcro AFTER EACH USE. Saturate Velcro with disinfectant and allow disinfectant to evaporate. (Ap­propriate disinfectant for nylon Velcro should be determined by the hospital.)

15

Litter Operation Guide

NIGHT LIGHT USAGE

The bed is equipped with two night lights to illuminate the
floor area around the bed.
There is a switch under the litter thigh section on the pa­tient’s left side that turns both lights on and off.

NOTE

The night lights have sensors so the lights will turn off, even
when the switch is on, if the light in the room is bright
enough so a night light is not necessary.

NURSE CALL BACK–UP BATTERY (Optional Equipment)

To prevent a low battery condition when the bed is not plugged in, position the cord out switch at the head
end of the bed to the off position. The switch is identified by the label shown below. If the switch is not posi­tioned as shown below and the bed power cord and pendant cord are unplugged, the life of the back–up bat­tery will be significantly reduced.
If the power light (located on the foot board) is flashing, the Nurse Call battery needs to be replaced. The
battery is located on the patient’s left side at the head end of the bed. No tools are required to replace the
battery. Unplug the bed power cord from the wall socket and replace the battery.

CPR BOARD USAGE (Optional Equipment)

If the bed is equipped with the optional CPR board, it is stored on the bed’s head board. To remove it,
pull it away from the head board and lift it out of storage position. If the CPR board option was not pur­chased, the head board can also be removed and used as an emergency CPR board.

Siderail Operation Guide

POSITIONING SIDERAILS

NOTE

The siderails can be locked at two heights (intermediate & full up).
The siderails can be tucked away under the bed when not in use. T o remove the rail from the tucked position,

grasp the top of the rail and pull outward.
To engage the head end siderail, grasp the rail and swing it upward to full height. When the siderail is being

raised, it does not lock in the intermediate position. To lower the siderail, push in the blue release handle (A)
and rotate the siderail until it locks in the intermediate position. To lower the siderail fully, push in the blue
release handle (A) again and rotate the siderail until it is completely lowered.

To engage the foot end siderail, the same procedure is required as for the head end siderail, however, the
siderail swings toward the foot end of the bed.

WARNING

Be sure the siderail is locked se­curely into position. Siderails are
not intended to keep patients
from exiting the bed. They are
designed to keep a patient
from inadvertently rolling off
the bed. Proper restraint
methods should be utilized to
ensure the patient remains in bed.
The siderails are not intended to be
used as a push device.

A

To disengage the rail, push in the blue release handle (A) and swing the rail down to the desired height. Store
the siderails by tucking the rails under the bed. Rails must be in the full down position before they can be
tucked.

SIDERAIL CONTROL PANEL LIGHTS

The bed is equipped with lights to illuminate the head end siderail control panel and the red nurse call
switches. Both can be activated at the foot board control panel. Three settings are available for the control
panel lights: low, medium and high intensity. When all lights are off, push the siderail control light button at

Preventative Maintenance

CLEANING

Hand wash all surfaces of the bed with warm water and mild detergent. Dry thoroughly. Do not steam clean
or hose off the Secure II Bed. 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.

CAUTION

Quaternary Germicidal Disinfectants, used as directed, and/or Chlorine Bleach products, typically 5.25% So ­dium Hypochlorite in dilutions ranging between 1 part bleach to 100 parts water, and 2 parts bleach to 100
parts water are not considered mild detergents. THESE PRODUCTS ARE CORROSIVE IN NATURE AND
MAY CAUSE DAMAGE TO YOUR BED IF USED IMPROPERLY. If these types of products are used to clean
Stryker patient care equipment, measures must be taken to insure the beds are wiped with clean water and
thoroughly dried following cleaning. Failure to properly rinse and dry the beds 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.

Clean Velcro AFTER EACH USE. Saturate Velcro with disinfectant and allow disinfectant to evaporate. (Ap­propriate disinfectant for nylon Velcro should be determined by the hospital.)

In general, when used in those concentrations recommended by the manufacturer, either phenolic type or
quaternary type disinfectants can be used with Staph–Chek fabrics. Iodophor type disinfectants are not rec­ommended for use on Staph–Chek fabrics because staining may result. The following products have been

SCALE SYSTEM DIAGNOSTICS

Diagnostic Mode Functions:

1. Calibrate Scale: This may be required in the field if the scale CPU is replaced.

2. Display Corner: This function displays the individual corner weights for each load cell assembly and can

be used to isolate a defective load cell.

3. Init. to Defaults: This may be required in the field when replacing the scale CPU board.

4. Display Factors: This is factory preset.

5. Exit Diagnostics: Changes made in the diagnostic mode (with the exception of Calibrate Scale) must be

saved in permanent memory using this function. Switching off power without saving will reset all variables
to their previous values.

Diagnostic Mode:

NOTE

It requires two people to enable the diagnostic mode for the scale system.

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

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

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

4. After two seconds, release the LBS/KGS key. The scale monitor should read CALIBRATE SCALE. The

diagnostic mode is now active.

Displaying Individual Load Cell Outputs:

A defective load cell can be detected by entering diagnostics and displaying individual load cell outputs.

1. Enter the diagnostic mode. The scale monitor will display CALIBRATE when the diagnostic mode is active.

2. Repeatedly press and release LBS/KGS until the scale monitor displays DISPLAY CORNER.

3. Press and release SCALE ON. The scale monitor should display PICK CORNER NOW.

The four keys listed in the group below function as POSITION keys corresponding with the four corners
of the bed’s litter. Whenever the scale monitor displays PICK CORNER NOW, press one of these keys
to select the load cell assembly at the desired corner.

A. ZERO = head end, patient’s right side
B. DELTA = head end, patient’s left side
C. PLUS = foot end, patient’s right side
D. MINUS = foot end, patient’s left side

4. Press and release the position key that corresponds with the load cell to be checked. The scale monitor

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.

6. When all the load cell outputs have been checked, repeatedly press and release SCALE ON until scale

monitor displays EXIT DIAGNOSTICS. Press SCALE ON to exit diagnostics.
