WARNING / CAUTION / NOTE DEFINITION
The words WARNING, CAUTION and NOTE carry special meanings and should be carefully reviewed.
WARNING
Alerts the reader about a situation, which if not avoided, could result in death or serious injury. It may also
describe potential serious adverse reactions and safety hazards.
CAUTION
Alerts the reader of a potentially hazardous situation, which if not avoided, may result in minor or moderate
injury to the user or patient or damage to the equipment or other property. This includes special care neces-
sary for the safe and effective use of the device and the care necessary to avoid damage to a device that
may occur as a result of use or misuse.
NOTE
This provides special information to make maintenance easier or important instructions clearer.
SAFETY TIPS AND GUIDELINES
Before operating the 2030, 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
SThe 2030 is not intended for use with patients less than two years of age.
SPowered bed mechanisms can cause serious injury. Operate bed only when all persons are clear of the
mechanisms.
STo help reduce the number and severity of falls by patients, always leave the bed in the lowest position
when the patient is unattended.
SWhen 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.
SAlways 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). 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. When moving the bed, toggle the steer pedal to put the bed in the steer mode. This
locks the swivel motion of the right foot end caster and makes the bed easier to move.
SThe Bed Exit System is intended only to aid in the detection of a patient exiting the bed. 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 bed after arming the bed exit system may cause a reduction in the sensitiv-
ity of the bed exit system.
SAlways unplug bed during service or cleaning. When working under the bed with the bed in the high posi-
tion, always place blocks under the litter frame and set the brakes to prevent injury in case the Bed Down
switch is accidently pressed.
SExplosion Hazard − do not use bed in the presence of flammable anesthetics.
SWhen using the Symmetric AireTM Mattress extra caution and/or operator supervision is required to help
reduce the likelihood of a patient fall occurring.

WARNING
To avoid possible injury and to assure proper operation when using a powered mattress replacement system
such as XPRT:
SConfirm proper scale system operation following mattress installation. For best results, secure the thera-
py mattress power cord to prevent damage to the cord or interference with the bed frame and the scale
system.
SDo not zero bed scales or weigh patient with Percussion, Vibration, Rotation or Turn−Assist active. Pa-
tient motion and position resulting from the dynamic therapy mattress may adversely affect scale system
performance.
SDo no 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.
SWhen using an XPRT Therapy Mattress extra caution and/or operator supervision is required to help re-
duce the likelihood of a patient fall occurring.
CAUTION
SThe 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 func-
tions should be locked and to use the buttons accordingly.
SBecause individual beds may have different options, foot boards should not be moved from one bed to
another. Mixing foot boards could result in unpredictable bed operation.
SWhen 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.
SPreventative maintenance should be performed at a minimum of annually 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 MA maximum, scale and bed exit systems calibrated properly.

SET−UP PROCEDURES
It is important that the 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 2030 is equipped with a hospital grade plug for protection against shock hazard. It must be plugged di-
rectly into a properly grounded three−prong receptacle. Grounding reliability can be achieved only when a
hospital grade receptacle is used.
Ensure the siderails raise, lower and store smoothly and lock in the up and intermediate positions.
Ensure that all four casters lock when the brake pedal is engaged
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.
Run through each function on both head end siderails to ensure that each is working properly.
If any problems are found during bed set−up, contact Stryker Customer Service at 800−327−0770.
