Important safety notice
Photosensitive seizure warning
A very small percentage of people may experience a seizure when exposed to certain visual images, including
flashing lights or patterns that may appear in video games. Even people who have no history of seizures or
epilepsy may have an undiagnosed condition that can cause these “photosensitive epileptic seizures” while
watching video games. These seizures may have a variety of symptoms, including altered vision, eye or face
twitching, jerking or shaking of arms or legs, disorientation, confusion, or momentary loss of awareness.
Seizures may also cause loss of consciousness or convulsions that can lead to injury.
Immediately discontinue playing and consult a doctor if you experience any of these symptoms. Parents should
watch for or ask their children about the above symptoms.

Safety
K-FORCE products have been designed with the greatest concern for safety.
•Do not use the system or accessories near water
•Do not allow small particles or liquid particles or other small objects to get into the K-FORCE system or
any of its accessories
•Do not expose the system to dust, steam or smoke. Don't place or use the system in areas with
excessive smoke or dust.
•Don't expose any K-FORCE components to high temperatures, high humidity, or direct sunlight.
•Don't place any K-FORCE components on unstable surfaces, or surfaces subject to vibration.
•When carrying a K-FORCE component, be careful to have a good grip in order to avoid the fall of the
system which may cause damage or injury.
•Never disassemble or modify the system or accessories. Use the system according to the instructions
in this documentation or any other documentation provided by KINVENT. No authorization is provided
for any modification, analysis of circuit or mechanics configurations. An unauthorized modification will
void your warranty.

useful for obtaining practical metrics on your participants accompanied with an acoustic and visual feedback.
After having turned on the device, the pairing is automatically done.
While your device is connecting, don't load the device, don’t step on the device, don't move the device and
don't put force on the device.
Figure 4, Basic Grip Exercise Screen
Info on this screen:
The manometer shows the force applied on a K-FORCE device in real-time. On the right top
corner you can check the device connection state . Click on to see the
details of the exercise choosen.
You can follow-up the results of each repetition, such as Max Force, Average Force and Success Percentage
(amount of time when Force is above Target)
Control the exercise state through the Buttons "Reset" and "Go/Stop".
Check one limb at a time. It is very important to properly choose the correct limb side (right or left) as this will
affect the database results.
You can stop an exercise even before completing the total amount of repetitions asked in the first place. Just
click on "Stop". The work done will be saved in the database
Check your results in the database as shown previously.
