6 Care and maintenance
General maintenance procedures
The operator of the Virtual SVV™ system is responsible for maintaining the medical product in faultless
condition. The functionality and condition of all components should be checked regularly. The disposable
items (face cushions, head strap and safety loop) should be exchanged or discarded as described.
In each delivered system the three component devices – base station, handheld remote and virtual reality
goggle – are factory-matched and carry the same serial number. Exchanging any of these components
should be carried out by the manufacturer. Each Virtual SVV™ system is calibrated at the manufacturer’s
facility. Under normal usage conditions recalibration is not necessary.
Damage to devices
In the following situations the Virtual SVV™ system should not be used until a qualified inspection has
been performed:
1. One or more devices have been mechanically damaged (e.g. through impact).
2. A liquid has penetrated into one or more of the devices.
3. A cable or connector is defective.
In these or comparable situations, contact the distributor.
Exchanging the padded face cushion
The padded face cushions are intended as single-use, disposable items. They must be exchanged
before each new patient is tested.
Replacing face cushion pads for each use is necessary to avoid the possibility of cross-infection.
The face cushion is bonded to the virtual reality goggle by a number of small Velcro® hook points. The
face cushion can, therefore, be simply removed. Perform the procedure as described in chapter 3.
Exchanging the head strap
The head strap is subject to wear and tear after repeated use. It should be exchanged when this
becomes apparent. The instructions provided in chapter 3 for attaching the strap can be performed in
reverse to remove the used item.
Battery care
Follow the instructions for battery use and care to ensure long life.
•
The built-in NiMH batteries are rechargeable. Under no circumstances should alkaline (non-
rechargeable) batteries be used
•
Only charge the batteries within the specified temperature range
•
Use only the delivered power adaptor. Using other power sources could damage the batteries
•
Take into consideration that a new battery reaches its full capacity after several charging cycles
•
Never short-circuit the contacts on the handheld remote or in the cradle of the Base Station. This
would damage the device!
