clothing changes, etc.). Bed should be at lowest convenient height for entry or exit. Failure to do so
could result in injury.
Warning: Possible Injury Or Death. Floor and caster locks must be locked prior to any
patient transfer or patient use of the bed. Failure to do so could result in injury or death.
Warning: Possible Injury Or Death. Patients with reduced mental acuity should not be
allowed access to pendant for risk of cord entanglement. Unsupervised use of pendant could result
in injury or death.
Warning: Possible Injury Or Death. Bed safe working load is 600 pounds. The safe working
load includes weight counting patient, mattress, bedding and any other equipment. Do not exceed
600-pound safe working load. Exceeding the safe working load could result in property damage,
injury or death.
Warning: Possible Injury. Do not use the product outside the recommended patient height,
width, and weight ranges. The general physical description of an adult is a person who is greater or
equal to 40kg in weight, 146cm in height, and with BMI greater or equal to 17.
Warning: Possible Fire Hazard. Use nasal mask or ½ bed tent oxygen administering
equipment. Oxygen tent should not extend below mattress support platform. Pendant should not be
placed in an oxygen-enriched environment such as an oxygen tent. Use of electrical circuits in an
oxygen-enriched environment could result in a fire hazard.
Warning: Possible Shock Hazard. Always unplug power cords from wall outlet before

performing any maintenance, cleaning, or service to the bed. Failure to do so could result in injury
or death. Note: In case of unexpected movement, disconnect battery and unplug bed from any
outlet.
Warning: Possible Shock Hazard. Injury may result from improper routing of the power cord.
Always follow the proper factory-installed routing configuration. Failure to do so could result in
injury or death. Do not position the device where access to mains connection cannot be
disconnected.
Warning: Possible Injury Or Death. Use a mattress that is properly sized to fit mattress bed
deck, which will remain centered on mattress bed deck relative to State and Federal guidelines.
Length and width should match mattress bed deck. Use of an improperly fitted mattress could result
in injury or death.
Warning: Possible Injury Or Death. If a patient’s mental or physical condition could lead to
patient entrapment, the mattress bed deck should be left in the flat and lowest position when
unattended. Failure to do so could result in injury or death.
Warning: Possible Injury or Death. An optimal bed system assessment should be
conducted on each patient by a qualified clinician or medical provider to ensure maximum safety of
the patient. The assessment should be conducted within the context of, and in compliance with, the
state and federal guidelines related to the use of restraints and bed system entrapment guidance,
including the Clinical Guidance for the Assessment and Implementation of Side Rails published by
the Hospital Bed Safety Workgroup of the U.S. Food and Drug Administration. Further information
can be obtained at the following web address:
http://www.fda.gov/MedicalDevices/ProductsandMedicalProcedures/GeneralHospitalDevicesandS
upplies/HospitalBeds/default.htm.
Warning: Possible Injury Or Death. Use a properly sized mattress in order to minimize the
gap between the side of mattress and Side Rails/Assist Devices. This gap must be small enough to
prevent patient from getting his/her head or neck caught in this location. Make sure that raising or
lowering bed, or contouring the mattress support platform, does not create any hazardous gaps.
Excessive gaps may result in injury or death.
Warning: Possible Injury Or Death. Verify all Side Rails/Assist Devices are locked in place
before use. Failure to lock assist devices may result in injury or death.
Warning: Possible Injury Or Death. Do not use any replacement parts not manufactured,
marketed, or provided by Prius Healthcare USA. Use of unapproved replacement parts may result
in injury or death.
Warning: Possible Injury Or Death. If using accessories not manufactured, marketed, or provided

by Prius Healthcare USA, consult with the manufacturer for compatibility and limitations prior to use.
Failure to do so may result in injury or death.
Warning: Possible Shock Hazard. Bed power cord has a hospital-grade, 3-prong grounded
plug. Grounding reliability can only be achieved when equipment is connected to an equivalent
receptacle marked “hospital-grade”. If external grounding conductor is in doubt, operate bed from
backup battery. Failure to do so could result in injury.
Warning: Possible Equipment Damage Or Injury To Staff Members. Service and repair
must only be performed by qualified, authorized Prius Healthcare USA.

vapors. Failure to heed this warning could result in equipment damage, injury or death.
Caution: Stay clear of underneath the bed when adjusting or moving the bed.
Caution: Mattress bed deck is not grounded, nor does it have a potential equalization
connection point. To prevent injury to patient connected to intravascular or intercardial medical
equipment, alternate measure must be implemented to equalize the potential between mattress
support platform and medical equipment.
Warning: To reduce the risk of injury, ensure the mattress support platform is horizontal and
in the lowest position with the side rails fully raised and locked when moving the bed with a patient
in it. For best maneuverability, push the bed from the head end.
To avoid injury to the patient and/or user, do not attempt to move the bed laterally with the steer
engaged. The wheel cannot swivel.
Warning: The bed should not be used adjacent to, or stacked with, other equipment due to the
risk of electronic interference. If adjacent or stacked use is necessary, the bed should be observed
to verify normal operation in the configuration in which it will be used.
Warning: Using non-approved cables and accessories may negatively affect the EMC
performance.
Warning: Mobile RF communication equipment can affect Medical Electrical Equipment.
Warning: Medical electrical equipment needs special precautions regarding EMC and needs
to be installed and put into service according to the EMC information provided in this manual.
Warning: External equipment intended for connection to signal inputs, signal outputs or other

connectors shall comply with the relevant product standard. In addition, all such combinations –
Medical Electrical Systems – shall comply with the safety requirements stated in the general
standard IEC 60601-1. Any equipment not complying with the leakage current requirements in IEC
60601-1 shall be kept outside the patient environment i.e. at least 1.5 m from the patient support or
shall be supplied via a separation transformer to reduce the leakage currents.
Any person who connects external equipment to signal inputs, signal outputs or other connectors
has formed a Medical Electrical System and is therefore responsible for the system to comply with
the requirements. If in doubt, contact qualified medical technician or your local representative.
Caution: Particular precaution must be considered during exposure to strong emission source
such as High Frequency surgical equipment and similar devices. Do not route High Frequency

Bed System Entrapment Information
Although essential in the practice of long-term care, bedside assists, are subject of regulatory
review and evolution in design and use.
The U.S. Food and Drug Administration (FDA) has addressed the potential danger of entrapment
with new safety guidelines for medical beds. These guidelines recommend dimensional limits for
critical gaps and spaces between bed system components.
Entrapment zones involve the relationship of components often directly assembled by the
healthcare facility rather than the manufacturer. Therefore, compliance is the responsibility of the
facility.
