The batteries are partially charged by the manufacturer.
We recommend charging before rst use.
Connect the charging pad to charger using the provided
cable and place the battery pack on the charging pad. It
is possible to charge two battery packs simultaneously.
The charging indicator will be red when not charged and
turn green when the battery is fully charged.
Average charging time for an empty battery is 1.5 hours.
Battery packs may remain on the charging pad when not
in use. In this case, the charging pad must be connected
to the powered-on charger.
When your battery needs charging, the battery makes a
beep sound. Charge the unit at this point.
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. Your ExamVision dealer will be
able to advise you.
The working time of your battery varies with light
intensity. The lowest setting can give you up to 3.5 hours
continuous use, and the highest approximately 2 hours.
The lithium ion batteries for your Essential One are covered by
our warranty for one year from date of purchase.
