03 | Warnings / Safety Precautions
Please read this instruction manual thoroughly before using.
•
Failure to comply with safety precautions can result in the
•
QUATTRO malfunctioning and risk of injury to the user.
Initial operation of the QUATTRO should take place in the
•
presence of a trained care professional.
Do not open or modify any component(s) and DO NOT make
•
repairs on the QUATTRO unless otherwise directed in this IFU.
If any issues or concerns with the QUATTRO arise, contact
•
your Prosthetist for assistance.
Improper and unsafe use of QUATTRO may result in injury.
•
Do not use the QUATTRO while the battery is charging via the
•
wall charger. Be sure to disconnect from the charger prior to
putting on the prosthesis.
- Do not submerge Quattro while charging using the
Quattro Booster Battery Pack.
If unusual movement or wear is detected in a structural part
•
of the prosthesis at any time, immediately discontinue use
of the device and consult your Prosthetist.
The QUATTRO contains a Lithium-ion battery that is not field
•
replaceable and requires factory service for repair. Lithium-ion
batteries contain hazardous metals and should never be
disposed of in residential or commercial garbage. They
should never be incinerated because they may explode.
Reference local regulations for proper disposal of product.
If power is lost from the QUATTRO knee, it will default to
•
the Power-Off Flexion resistance setting.
When the battery is depleted, use extreme caution when
•
descending ramps and stairs.
The QUATTRO contains small parts and cords that can be
•
potential choking hazards.
If the QUATTRO has been stored outside its Operating
•
Temperature Range, allow the knee to acclimate to the
operating environment for a minimum of 30 minutes
before use.
Avoid running or other intense physical exercise above the
•
specified operating temperature limit (45 °C [113 °F]). This
can damage your QUATTRO.
The proximal connection to the patient is the Applied Part of
•
the device. All other external surfaces of the device, including
the power supply and cord, are the Accessible Parts.
Failure to comply with the instruction for use will void the
•
warranty.
