3.4.3 Suit, shirt, short maintenance
To wash the suit, shirt, shorts remove all cables, BP and MT’s. Follow the instructions on the label
inside the suit:
 Machine wash at 30°C – 85 F
 Do not bleach
 Do not iron
 Do not dry clean
 Do not tumble dry
For the headband and gloves, remove the MTx and use only cold hand wash.
3.4.4 FabriFoam Velcro Straps
Do not place in washing machine or dryer as this may damage the material. Hand wash in warm water.
Use mild detergent if soiled. Rinse well. Gently squeeze out excess water. Air dry, foam side up, on rack
or towel or hang to dry. It is best to wash regularly to keep the material clean and free of body salts, oils,
etc. This will help to prolong material life.
3.4.5 Dynamic movements
The MVN Suit/Straps should provide enough fastening for most movements. However, depending on
the individual anatomy and fit with the Suit/Straps it might be necessary to take additional steps to
ensure that the motion tracker follow the movement of the underlying body segment as well as possible.
In particular, for users who will carry out extreme movements, martial art, professional athletes or
jumping from heights; it is worth considering applying the provided straps over the Lycra suit as
reinforcements to make sure the motion trackers follow the movement of the underlying segment. These
straps should be tightly bound tape (be careful to not block the blood circulation!) over the locations of
the MT on the body. Additionally, in contact sports or other situations where there is a chance of physical
impact it might be beneficial to apply some protective measures (e.g. padding) to protect the person
wearing the MVN system as well as the MVN system itself.
3.4.6 Finding a magnetic “sweet spot”
In MVN Studio the icon of a magnet can be enabled to give an indication of magnetic environment.
When this is enabled, glowing balls appear at the hands, feet and pelvis. Green indicates a safe
magnetic environment. Subjects are advised to remain only in areas where indicators are green. If the
room is mainly red, at least find an area of green for calibration. Sometimes this can mean to go outside;
although often this step is not needed. See Section 19.2 for more details.
3.4.7 Warming up the filters
MVN Studio is based on Kalman filter algorithms. It is best to warm up the system, before making
recordings. To warm up the system, stand still for 30 seconds after the initial calibration pose. See
Section 19.9 and in particular 19.9.2 for more details.
3.4.8 CH5000 Charger Safety
 Do not expose the charger or power supply to water or liquids.
 Do not open the charger or power supply case, no user serviceable parts are inside.
 Do not cover the fan exhaust or obstruct the airflow, this will cause overheating.
 Use only the manufacturer’s power supply and observe terminal polarity.
 Place the charger in a cool spot, away from external heat sources
 Caution - during recalibration the charger may become warm.
