Virtual SVV™ Instructions for Use – US
•
Avoid interrupting the charging cycle before the yellow LED extinguishes
•
The integrated inactivity-timer in the handheld remote powers the system down after prolonged
inactivity in order to save battery capacity. The standard period of inactivity is set to 10 minutes.
This period can be increased (up to 30 minutes) if needed.
•
Avoid discharging the batteries so completely that the system closes down. This can shorten
battery life. Charge the batteries regularly when the charge indicator on the Operator GUI
changes to yellow or red.
•
Charge the batteries regularly, even during periods when seldom used
•
Do not expose the device to direct sunlight or high temperatures. This would, under certain
circumstances, affect the temperature-dependent charge control and the batteries would not be
charged completely.
•
The batteries should be exchanged if the capacity is so low such that SVV testing is unable to be
performed correctly. Follow the instructions in below on exchanging batteries.
Exchanging the built-In batteries
The batteries should be exchanged when its operative life becomes so short that examinations cannot be
performed in full. Proceed as follows:
Step 1
Switch off the handheld remote by pressing both right and left buttons for at least 5 seconds. The device is
powered down when the ON-LED extinguishes. Disconnect the cable to the virtual reality goggle.
Step 2
Using a small Philips screwdriver carefully remove the black securing screw on the battery compartment
cover on the rear side of the handheld remote. Be careful not to damage the screw thread.
Step 3
Slide the securing clip on the battery compartment cover downwards in order to open the cover.
