The battery is partially charged by the manufacturer.
We recommend charging before rst use.
Best practice is to keep your battery charged at more than
30%. Partial charges don’t harm your battery.
When your battery needs charging, the charge indicator
will start to blink. Charge the unit at this point.
To charge, attach the charger lead to the charger port.
The charge indicator (red light) will come on. When the
battery is fully charged, the charge indicator will light
green. We recommend disconnecting the unit at this point,
to maximize battery life.
When your battery is reaching the end of its natural life,
after about 500 charges, you will nd it will need to be
charged more frequently. When this starts to limit your
working time, it is time to have the battery replaced in the
control unit. Your ExamVision dealer will be able to arrange
this procedure.
The working time of your battery varies with light intensity.
The highest setting can give you more than 12 hours
continuous use.
